High Level Network Design

Hi Guys
I am posting this because I am starting my career into network design and want some help in it. I am at present in need of a high level design overview as I need to prepare some high level network design documents. Can anyone shower some thoughts in it as how about doing this and if any there is a template for HDD so that it maybe useful.
Also I believe in keeping information as transparent as possible to the readers of the document and need someone to explain in very simple terms if at all it is possible.
Thanks a lot
Vin

Hi Vin,
I would check the Cisco SBA and Validated Design Zone as a first pass.
Lots of great design documents there.
As for how I would create a high level design - keep it simple. You just want an overview of the connectivity - e.g. for a dual-site head office with 100+ branch wan, I would only show a single branch site as a template.
Every network is different, but the more documentation you write and read the more you will define your own style.
Apologies I can't give you any of my customer's documentation - NDA's and everything!
Regards, Ash,

High-level design for business process scenario

Hi all, I have a business process scenario for which CRM and ECC has to be used. The scenario is like this:
There are 2 subsidiaries of a company - A and B, which are into trading of materials.
Between A and customer there is sales agreement. Between B and vendor there is purchase agreement.
Whenever customer requires materials, it will send request to A. So, A creates a sales order. B in turn sends a request to vendor for which a purchase order is created. The vendor ships the goods directly to customer. The vendor bills B for the purchase order. B adds some margin and then it goes for inter-company settlement with A. A bills the customer for the materials. In this entire process, both A and B earns profit through margins.
It has to be noted that CRM has to be used as contact point with customer.
Now I have the following questions:
1. How would the high-level business design be like?
2. How would be the document flow?
3. How can inter-company settlement and billing be done?
All constructive comments and feedback will be rewarded.

Hi Animesh,
The thumb rule to CRM process designing is stick to customer process...
Thus u jst hav to stick to process design of company A and its interaction with Customer.
We are not concerned with how the material will be purchansed,but we are concerned with how we will be delivering it to end customer.
Thus, once customer place an order to company A, our process would suggest a sales order for the customer with one of the partner function "Vendor" as B with the required material. Now later process in R/3 would convert this sales order with customer as soldtoparty to purchase order with vendor as B and one of the secondary partner soldto party as our original customer.
And billing would happen the way it is... ie. based on sales order.. thus u will have some inflow.. again u will be raising a purchase requisition to company B thus that would be your outflow..
That was a really good scenario to think about.

Pratik Patel

Higher-level billing element for the selling company code in your network

Hi ,
I am getting the error " No wbs element found while substituting wbs element 00074419.at the time of creation of invoice from OBD
I ahve refered note 672929 , solution is "Define a higher-level billing element for the selling company code in your network" but then I odnt ahev anything defined in the network.
Pls guide me how to go about it
Regards
Suvin.Sugathen

HI,
- Any of the WBSE which are hierarchically superior to your WBSE "74419" should have the relevant company code.
Check for any such superior WBSE in your structure & assign the company code, in question, to it. It should be a billing element also.
this is because, while billing system checks for the proper revenue receiver cost object in the particular company code.

Design considerations for wrapping higher level process

So Ive used workflow now on a few projects and have become comfortable building/coding with it. Recently a discussion was started to design a new process to automate a part of the business Im in and there are several different departments, each with
their own different functions and processes that they perform. During this discussion, the thought came to me - why stop with just the "small" picture where I was using WF to contain and execute business rules, but also wrap the higher level
abstractions also.
For example, a department performs steps A, B and C. Each step might have some branching in it (if/then etc). Its only the "steps Im using workflow currently.
Above the department, there is another layer, lets call it "group". There would be several different groups, each with its own departments, some with the same name as other groups, but the internal structure might be different for a given
department between groups. So this means that if I modeled a department in one group, I cant assume I can reuse that department in another groups workflow.
My main unknown however, is how would a user interact with a workflow that was this high level. Abstracting higher levels, means users dont need to interact with or execute the whole workflow each time, only a part of it. So am I looking at pausing/resuming
the bigger workflow? How can I "skip" to a certain stage or area of a workflow, bypassing the stuff that has already been done?
Correct me if Im wrong, but this seems to be where I need to look at bookmarks?
In my case, something similar to an order in a shopping cart is what would be the input type for the bigger workflow. There are several different groups of users that have to set or add properties to associated objects (sql tables) related to the order
before it can be marked "complete".
How would you tie together a "wizard" type concept with workflow? This seems to be the type of model we are considering. A user takes an order a few steps, then another user from a different group/department adds some attributes and
the workflow/wizard continues a few more levels down. Finally, after all the rules have been matched and required data provided, the workflow can "finish".
Hope my description seems clear.

If you want to skip to certain state or bypass what stuff that has been done, you need give logic judgment first. Bookmarks are the mechanism that enables an activity to passively wait for input without holding onto a workflow thread. When an activity signals
that it is waiting for stimulus, it can create a bookmark. So bookmark is available for you during create this application.
Here are some workflow applications, see:

High-Level JTS/TopLink design question

I've gone through the "using JTS with TopLink" docs, and it mostly makes sense. However, I still don't understand how TopLink "knows" when I call acquireUnitOfWork() whether or not I'm participating in a distributed 2PC transaction.
Said another way:
Let's say I've got an application based on TopLink (registering appropriate JTS stuff) that exposes an API that can be accessed remotely (RMI, SOAP, whatever).
And, I've got another, separate application using a different persistence-layer technology (also supporting JTS) that also has an API.
Now, I create a business method that uses the APIs from both of these applications, and I want them to participate in a single, distributed transaction.
At a high level (source code is unnecessary), how does that work?
Would the API need to support an ability to specifiy a TransactionContext or is this all handled behind the scenes by the 2 systems registering with the Transaction Service?
If this is all handled through registration, how do these 2 systems know that these specific calls are all part of the same XA transaction?

Nate,
TopLink particiaptes in JTA/JTS transactions but dows not control them. When you configure TopLink to use the JTA/JTS services of the host application server you are deferring TX control to the J2EE container. TopLink will in this case register each acquired UnitOfWork in the current active TX from the container. The container will also ensure that the JDBC connection provided to TopLink is also bound by the active TX.
In order to get 2PC you must register multiple resources into the same JTA TX. The TX processing during commit will then make the appropriate call backs to the underlying data source as well as the necessary call backs to listeners suchs as TopLink to have its SQL issued against the database.
In short: The J2EE container manages the 2PC TX and TopLink is just a participant.

Ask the Expert: Hierarchical Network Design, Includes Core, Distribution, and Access

Welcome to the Cisco® Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about hierarchical network design.
Recommending a network topology is required for meeting a customer's corporate network design needs in their business and technical goals and often consists of many interrelated components. The hierarchical design made this easier like "divide and conquer" the job and develop the design in layers.
Network design experts have developed the hierarchical network design model to help to develop a topology in discrete layers. Each layer can be focused on specific functions, to select the right systems and features for the layer.
A typical hierarchical topology is
A core layer of high-end routers and switches that are optimized for availability and performance.
A distribution layer of routers and switches that implement policies.
An access layer that connects users via lower-end switches and wireless access points.

Dear Leo,
We are discussing the following without any product line, discussing the concept of hierarchical design, which will help you to take decision which model is better for you Two Layer or Three Layer hierarchical model.
Two-Layer Hierarchy
In many networks, you need only two layers to fulfill all of the layer functions—core and aggregation
Only one zone exists within the core, and many zones are in the aggregation layer. Examine each of the layer functions to see where it occurs in a two-layer design:
Traffic forwarding—Ideally, all interzone traffic forwarding occurs in the core. Traffic flows from each zone within the aggregation layer up the hierarchy into the network core and then back down the hierarchy into other aggregation zones.
Aggregation—Aggregation occurs along the core/aggregation layer border, allowing only interzone traffic to pass between the aggregation and core layers. This also provides an edge for traffic engineering services to be deployed along.
Routing policy—Routing policy is deployed along the edge of the core and the aggregation layers, generally as routes are advertised from the aggregation layer into the core.
User attachment—User devices and servers are attached to zones within the aggregation layer. This separation of end devices into the aggregation permits the separation of traffic between traffic through a link and traffic to a link, or device. Typically, it is best not to mix transit and destination traffic in the same area of the network.
Controlling traffic admittance—Traffic admittance control always occurs where user and server devices are attached to the network, which is in the aggregation layer. You can also place traffic admittance controls at the aggregation points exiting from the aggregation layer into the core of the network, but this is not common.
You can see, then, how dividing the network into layers enables you to make each layer specialized and to hide information between the layers. For instance, the traffic admittance policy implemented along the edge of the aggregation layer is entirely hidden from the network core.
You also use the core/aggregation layer edge to hide information about the topology of routing zones from each other, through summarization. Each zone within the aggregation layer should have minimal routing information, possibly just how to make it to the network core through a default route, and no information about the topology of the network core. At the same time, the zones within the aggregation layer should summarize their reachability information into as few routing advertisements as possible at their edge with the core and hide their topology information from the network core.
Three-Layer Hierarchy
A three-layer hierarchy divides these same responsibilities through zones in three vertical network layers,
Traffic Forwarding—As with a two-layer hierarchy, all interzone traffic within a three- layer hierarchy should flow up the hierarchy, through the layers, and back down the hierarchy.
Aggregation—A three-layer hierarchy has two aggregation points:
At the edge of the access layer going into the distribution layer
At the edge of the distribution layer going into the core
At the edge of the access layer, you aggregate traffic in two places: within each access zone and flowing into the distribution layer. In the same way, you aggregate interzone traffic at the distribution layer and traffic leaving the distribution layer toward the network core. The distribution layer and core are ideal places to deploy traffic engineering within a network.
Routing policy—The routing policy is deployed within the distribution layer in a three- layer design and along the distribution/core edge. You can also deploy routing policies along the access/distribution edge, particularly route and topology summarization, to hide information from other zones that are attached to the same distribution layer zone.
User attachment—User devices and servers are attached to zones within the access layer. This separation of end devices into the access layer permits the separation of traffic between traffic through a link and traffic to a link, or device. Typically, you do not want to mix transit and destination traffic in the same area of the network.
Controlling traffic admittance—Traffic admittance control always occurs where user and server devices are attached to the network, which is in the access layer. You can also place traffic admittance controls at the aggregation points along the aggregation/core edge.
As you can see, the concepts that are applied to two- and three-layer designs are similar, but you have more application points in a three-layer design.
Now the confusion takes place in our minds where do we use Two Layer and where the Three layer hierarchical model.
Now we are discussing that How Many Layers to Use in Network Design?
Which network design is better: two layers or three layers? As with almost all things in network design, it all depends. Examine some of the following factors involved in deciding whether to build a two- or three-layer network:
Network geography—Networks that cover a smaller geographic space, such as a single campus or a small number of interconnected campuses, tend to work well as two-layer designs. Networks spanning large geographic areas, such as a country, continent, or even the entire globe, often work better as three layer designs.
Network topology depth—Networks with a compressed, or flattened, topology tend to work better as two-layer hierarchies. For instance, service provider networks cover large geographic areas, but reducing number of hops through the network is critical in providing the services they sell; therefore, they are often built on a two-layer design. Networks with substantial depth in their topologies, however, tend to work better as three-layer designs.
Network topology design—Highly meshed networks, with many requirements for interzone traffic flows, tend to work better as two-layer designs. Simplifying the hierarchy to two levels tends to focus the design elements into meshier zones. Networks that focus traffic flows on well-placed distributed resources, or centralized resources, such as a network with a large number of remote sites connecting to a number of centralized Data Centers, tend to work better as three-layer designs.
Policy implementation—If policies of a network tend to focus on traffic engineering, two-layer designs tend to work better. Networks that attempt to limit access to resources attached to the network and other types of policies tend to work better as three-layer designs.
Again, however, these are simple rules of thumb. No definitive way exists to decide whether a network should have two or three layers. Likewise, you cannot point to a single factor and say, “Because of this, the network we are working on should have three layers instead of two.”
I hope that this helps you to understand the purposes of Two Layer & Three layer Hierarchical Model.

Running a Sub-VI and monitoring data that is generated on a higher level VI

Hi All,
This question must been there before, but I cannot find a suitable answer here on the forums....
I have a 'top-level' VI that does a lot of things. I also have a sub VI that runs a frequency sweep on a piece of equipment. This is done with a for loop.
Problem:
I want to monitor/access the data that is generated in the for loop (See attached, the 3 wires within the green circle I want to monitor).
2 Questions:
How can I access the data on the wires (within the loop) from a higher level VI?
How can I then run this VI in a higher level VI while the higher level VI is continuing and not waiting for the sub-VI to complete?
I tried using a Que but I cannot seem to get that working.
Any suggestions?
Regards,

The queue is a good way to move data from a running subVI to another VI. Your problem is that if the subVI is inside a loop in the main VI, that loop in the main VI cannot iterate until the subVI completes. The solution: have the sub VI running in parallel - not inside - the loop.
Look at the Producer/Consumer Design Patterns (at File >> New... >> VI >> From Template >> Frameworks >> Design Patterns >> Producer/Consumer. This may be more than you need at the moment but will show how the parallel code process works.

Why does OWB 9.2 generate UK's on higher levels of a dimension?

When you specify levels in a dimension, OWB 9.2 generates unique key constraints in the table properties for every level, but only the UK on the lowest level is visible in the configuration properties. Why then are these higher level UK's generated? Is this a half baked attempt to implement the possiblility to generate a snow flake model in OWB?
Jaap.

Piotr, Roald and others,
This is indeed a topic we spend a lot of our time on these past months. We are addressing this as (in my old days I had the same problem as a consultant) we know that this is a common problem.
So the solution is one that goes in 2 directions:
- Snowflake support
- Advanced dimension data loading
Snowflake is obvious, may not be desired for various reasons but we will start supporting this and loading data for it in mapping.
If you want a star table, you will know that a completely flattened table with day at the lowest level will not be able to get you a unique entry for month. So what people tend to do is one of the following:
- Proclaim the first of the month the Month entry point (this stays closest to the star table and simply relies on semantics on both ETL and query side).
- Create extra day level entries which simbolize the month, so you have a day level with extra entries
- Create views, extra tables etc to cover the extra data
- Create a data set within the tables that solves the key problem
We have opted for the last one. What you need to do for this is a set of records that uniquely identify any record in any level. Then you add a key which links to the dimension at the same point (a dimension key), so all facts always use this surrogate key to link (makes life in query tools easier).
For a time dimension you will have a set of day records with their months etc in them (the regular star). Then you add a set of records with NULL in the day having months and up. And you go up the hierarchy. For this we will have the ETL logic (in other words you as a designer do not worry about this!). On the query tool you must be a little cautious on counts but this is doable and minor.
As you can see none of the solutions are completely transparent, but we believe this is one that solves a lot of problems and gives you the best of all worlds. We will also support the same data structure in the OLAP dimensions for the database as well in the relational dimension. NOTE that there are some disclaimers with this as we are doing software here...
In principal however we will solve your problem.
Hope this explains some of our plans in this area.

High Level Thread Implementation Questions

Hi,
Before I take the plunge and program my software using threads, I have a few high-level questions.
I plan on having a simulation class that intantiates software agents, each with different parameters. There is an agent class, with constructor, methods etc. Each agent has a sequence to go through. Once completed, the iteration number is increased and the sequence is repeated. That's simple enough to do.
The question is, is it worth executing each agent on a different thread?
If there is around 500 - 1000 lines of code (crude measurement, I know) how many can I expect to thread efficiently?
One parameter allows an agent to execute n cycles for each global iteration. (i.e. in one iteration, agent A runs once, agent B runs 5 times). Could this be a problem? Should this be controlled outside the agent, or inside it?
Can I write the code without having to worry about threading, or do I have to design the agent code with threading in mind?
Will they really run in parallel? It is important that there is no bias to the execution order. I can solve this messily without using threads by randomising the execution order - but that is a messy work around - and why I'm looking at threads.
Can threaded objects interact easily with non threaded one when execution order is important?
Are there any other points that I should consider?
Thanks in advance - any information before I enter this unchartered territory will be truly appreciated!!

I think you are better off running this all in a single thread.
Threads make no guarantee as to scheduling. Threads do not increase efficiency (unless your agents block on i/o, or sleep). Threads come with an overhead cost.
Threads don't guarantee no bias to execution order.
Threads require synchronization to ensure safe interaction between each other. This is a bit of extra work, and can be a bitch if you're not familiar with it.
Yes, threads run in parallel. If you have multiple processors then they can truly run in parallel, otherwise they run in time slices.

Not sure exactly what you mean by errors. If they show up in your Scan Log, then they almost always involved files that you don't have read access to.
If they were errors during Definitions Update there will be more in your Update Log and are usually network related.
If they were infections then I would need to know the infection name and exact location of the file in order to be able to advise you on those.
To get detailed infomation on what ClamXav has found, after completing the scan, click in the top pane of the ClamXav window where it shows the Infection / File Name / Status to make sure it's in front and type the key combinations <command>-A, <command>-C (or choose "Select-All", "Copy" from the "Edit" menu) to copy the information to your clipboard, then come back here and type <command>-V or choose "Paste" to show us what was found where.

Q on High level interrupt??

we're porting our driver for our PCI board from NT to Solaris. When I load my driver, it shows it was assigned a hi_level interrupt in the attach() routine. If I try to get block cookie or register the ISR for this "hi_level" interrupt, the OS complains my device at IPL 12 conflicts with other device at IRQ 5 IPL 1..
so I have to add
interrupt-priorities=9;
in my driver.conf file to force it to use low level IPL.
I don't think there's hardware problem on our board since they're working fine under NT. My questions are
1. Why OS assign me a high level interrupt by default?
2. Am I allowed to use the hi level interrupt?
3. how to register a hi level interrupt?
Thanks alot.

routine to assign IPLs to pci devices:
int pci_devclass_to_ipl(int pci_devclass)
switch ((pci_devclass & 0xff0000) >> 16) {
default:
case PCI_CLASS_NONE: /* class code for pre-2.0 devices */
return 1;
case PCI_CLASS_MASS: /* Mass storage Controller class */
return 5;
case PCI_CLASS_NET: /* Network Controller class */
return 6;
case PCI_CLASS_DISPLAY: /* Display Controller class */
return 9;
case PCI_CLASS_MM: /* Multimedia Controller class */
case PCI_CLASS_MEM: /* Memory Controller class */
case PCI_CLASS_BRIDGE: /* Bridge Controller class */
return 12;
Don't know why sun has deciced that multimedia, memory
and bridge pci controllers must have an IPL 12 (= hi level
interrupt). The solution is indeed to add an
"interrupt-priorities=9;" line to your driver's .conf file to work
around this problem and get rid of the hilevel interrrupt.
My audio driver's (->multimedia) attach routine verifies that
the interrupt-priorities line is in use by making sure the
device is not registered for a hilevel interrupt, like this:
xxx_attach(...)
* Make sure we're not using a high level interrupt handler.
if (ddi_intr_hilevel(dip, 0)) {
cmn_err(CE_NOTE, "Driver does not support high level interrupt.");
cmn_err(CE_NOTE, "You should probably add 'interrupt-priorities=9;' to xxx.conf");
return DDI_FAILURE;

High level process model for a Pulp & Paper Industry

Hi:
Someone can help me?, i'm looking for a organizational reference model for a pulp & paper company, under the alignment for best practices in to SAP R/3
I need know what is the best model for this kind company (chain value, macro process, business process, sub process...)
Thanks in advance

hi,
thanks for yor points.
at that time it was opened.for me also it was warning the same, any way iam providing some more info on it. pls have a look on it.
Pulp and paper industry facing IT modernisation needs
Today most pulp and paper industry companies face serious financial challenges to increase return on investment and improve capital utilisation.
Companies are working to improve the efficiency of their supply chains and thereby reduce working capital, increase transaction velocity and improve inventory turnover. Mergers, acquisitions and alliances are reshaping the pulp and paper industry. Although the pulp and paper industry has invested heavily in IT systems, a large variety of old systems is often complex, inflexible in regard to integration and difficult to operate. As they reflect past organisations and business models, the streamlining of business processes is difficult.
Mega trends in the pulp and paper industry IT.
The pulp and paper industry is stepping into a new phase of business evolution driven by consolidation of industry, globalisation and ever-increasing competition. These market drivers are forcing the pulp and paper industry to put a greater focus on cost efficiency. These focuses are creating totally new challenges for the organisation, specifically in the IT area.
IT is increasingly becoming a commodity. This is a result of product standardisation and the popularity of off-the-shelf-products that facilitate the economies of scale. This phenomenon is also supported by increasing utilisation of competence resources in low-cost countries.
Managing change becomes more and more difficult. Very often companies face the need for new changes before they have seen the benefits of the previous ones. The cycle of change is short and the transformation environment becomes very complicated. On the other hand, IT becomes the tool in forcing business changes to happen. Often the only practical way to roll out new processes and practices is through the modernisation of information systems.
Like many other industries, the pulp and paper industry is concentrating on providing digitalised self-services as part of their business development.
Industry background
Since the consolidation and globalisation of the pulp and paper industry, there has been increasing pressure to continuously improve both its internal and external efficiency. In the large pulp and paper mills, production management systems typically consist of several different systems, which might also be from different suppliers. Systems are often isolated islands, which are successful in managing information of their own area but they lack the comprehensive information exploiting and sharing. This has resulted in a complex and inflexible architecture of legacy systems. These legacy systems are expensive to manage and difficult to develop to meet business requirements.
This pressure has led to massive IT investments and a continuous rebuild of the IT environments in order to meet efficiency challenges. Although many pulp and paper mills have invested a lot in building up their business supporting IT, especially Enterprise Resource Planning (ERP) systems, the return on investment is often difficult to measure. There is a lot of potential to improve usability of systems by harmonising business processes and integrating the systems more efficiently in order to better support actual business needs.
Most pulp and paper industry companies have thus come to a point where a more radical rebuild and renewal of the entire IT and network environment is required. Fortunately, the conditions for this have improved over the last few years, due largely to an increasing range of commercially available application platforms adopted for the pulp and paper industry, the acceptance of common industry standards, and the evolution of refined integration and migration methods.
Renewing and harmonising the companys operations and IT systems is still, however, a demanding undertaking. Securing continuous operations, while at the same time replacing the core systems and processes, requires a high level of expertise in pulp and paper industry processes and information technology. To complement the in-house competence, the pulp and paper industry will need to establish partnerships with outside solution providers and system integrators. To minimise risks and keep control of business-critical technology, new delivery models will be a necessity.
