Point-to-point Vs 1-to-n scenario using XI- Architecture qtn

Hi All,
If we want to avoid p-p interfaces using XI, do we keep secnario like
If we have e sources, reciving similar info, but with different cannonical, and going to target(SAP) as one IDOC.
Receiver determination ?
1. S1-XI(XI As bsuiness system), S2- XI(XI As bsuiness system), S3-XI(XI As bsuiness system) and then XI-SAP(IDOC) ?
or
2. S1-SAP, S2-SAP, S3-SAP ? if this is the case, how do u justify it is not point-point
3. S1-BPM,S2-BPM, s3-BPM, and thenBPM-SAP is possible, but want to avoid BPM ?
Thanks

Hi,
I understand xi reduces TCO, but technically if u look at if u have want to reduce no of sources to go thru xi to finally one interface to SAP
S1-XI, S2-XI, s3-XI ( these three similar cannonical with slight change)
XI-SAP ( above 3 fit into one type of idoc interface)
to avoid p-p, which one correct way of doing and is good fit ?
1. S1-XI(business service XI)
S2-XI(business service XI)
S3-XI(business service XI)
and then one interface XI-SAP
OR
2. S1-SAP (via XI, here receiver determination is taking sender source S1 to SAP )
S2-SAP (via XI, here receiver determination is taking sender source S2 to SAP )
S3-SAP (via XI, here receiver determination is taking sender source S3 to SAP )
2nd scenarion, it is still kind of Point-point ?
OR
3. S1-BPM
S2-BPM
S3-BPM
and then one interface BPM-SAP
which one is correct way of doing and why?

Point to point IP telephony help neede

hi all,
im new to VOIP,i have 2 offices 10 km diff, i would like to implement ip telephones for communication between these 2 offices.my equipments are 2801 routers 2 no's and WIC-1T 2 no's point to point 128kbps leased line.maximum 10 users will use ip phone's in this scenario. what all things are required extra other than IP phones.
how can i configure these 2 routers for this scenario.whats the encapsulation for this configuration.pls give me the sample configuration also.
any post will be appreciated with proper rating.

128kbps leased line is not a lot of bandwidth if you do a lot of intersite calling. You can use g729 as the codec, which will give you upto 24kbps * 5 (5 calls).
Are you running Callmanager or Callmanager express ? Cheapest solution would be to run two independent callmanager express systems on each router. If running CME, you will need,
a. CME feature license (preferably get the 2800 CME bundle which comes with DSPs and feature licenses)
b. IP Phone licenses for CCME
c. A inline powered switch or power bricks, power injector or power patch panel
d. You will need to setup some form of CAC (preferably a gatekeeper) to ensure that your calls between offices doesnt go beyond 3 or 4.
e. If you do a lot of interoffice calling, you should resort to routing calls via PSTN, if you dont have the budget to increase the bandwidth between the two sites.
IF using Callmanager, you can put the server in one site and the other site may run SRST or CME. IN this case you will need,
a. Callmanager server and software
b. Phones licenses for Callmanager
c. SRST bundle (2800) for remote site
d. Voice gateway bundle (2800) for main site
e. inline powered switch.
For voicemail I think the best solution in this case will be to use CUE.

You will need a switch at each location for the IP phones to connect to the network. Preferably, you would have a switch capable of delivering power to the phones, such as the Catalyst 3560-24PS. You will need either Callmanager or Callmanager Express for call processing. Callmanager Express can run on your 2801 and will support up to 240 phones. Callmanager is a much more scalable product and runs on separate server hardware. Depending on the number of lines at each location you will need a VWIC card in each router to support local dial tone. Examples are the VWIC-1MFT-T1 for PRI and the VIC2-2FXO or VIC2-4FXO for analog lines. You will also need to take bandwidth into consideration. G.711 calls take approximately 80k and G.729 calls take approximately 24k. 2 G.711 calls would take up the entire circuit. If you're going to be running several calls across this link as well as data, you will need to consider increasing the link speed. Also, Callmanager Express has no provision for Call Admission Control. CAC is the ability to limit the number of calls across a given link in order to avoid quality degradation. You will want to employ QoS mechanisms so that voice traffic gets preferential treatment no matter how much bandwidth you have. Take a look at the Qos link below for an overview. The configuration required would get quite lengthy for this post, but the admin guide below will give you a good place to start.

Point to Point webservice communication

Hi Experts,
Could you please tell me, how to do point to point webservice communcation using Enterprise Portal?
Regards

How to make a Line Chart curved instead of straight from point-to-point?

I have a Line Chart that is is very jagged and plots directly from point to point, like this:

L2 Failover Plan for Point to Point

We have 2 point to point links from 2 different ISP's for the purpose of connecting to our data center from our office. We would like to configure a failover scenario using these two P2P links.
I have been trying with the sTP method but for some reason we could not succeed in this, could be because of the distance.
Please help me to implement a failover P2P conectivity usign this two links.

Hello,
Is there a specific reason you are using Layer 2 between sites? If the links are the same bandwidth you could create a port-channel - where both physical links become one logical link, this is ideal because the fail-over is seamless without losing any connectivity and is far superior to spanning-tree.
To configure this:
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet1/0/1
description Link to ISP1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 1 mode active
interface GigabitEthernet1/0/2
description Link to ISP2
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 1 mode active
This could also be accomplished with IP routing. you can can configure the interfaces as layer 3 ports and setup a routing protocol between sites - Like EIGRP. EIGRP can do equal and unequal cost load balancing or simply route all traffic via one link and automatically route via the other if the primary went down.
If you provide more data I could offer more assitance with design and configuration.

VLAN info across a Point-to-Point WAN circuit

What is the best way to temporarily pass VALN info across a Point-to-Point T1 WAN circuit. Here is a simple layout:
I have a 355012G at the Corporate Core with several VLANs for domain login, IP phones, file servers, printers, etc. I have a remote location that is currently getting the VLAN info across a wireless bridge (2 1300s and a 3500XL switch at the remote warehouse. The customer wants to connect the remote site with a Point-to-Point T1 and a new 35660 switch as follows:
MAIN-------------------------------------------REMOTE
355012G---e---3560R--------P-to-P------2610R--e--3560
What would be the best design / config scenario for passing the CORE VLAN info across the WAN P-to-P?
I was thinking bridging?
Any thoughts?

I have been thinking about this for a while and I can't find a way to do it. I know you can do embedded trunks but that is not what you are asking to do. The only alternative you have is to bridge the traffic.
Sorry can't be more helpful than that but since no one else has responded I figured I would giev my 2 cents for what it might be worth.

I am extremely upset. I purchased my iPad in SA and I am traveling in Greece. When I want to make use of the free apps, I get a message that the app is not available in the SA store. What is the point of having an iPad if you cannot use it worldwide?

I am extremely upset. I purchased my iPad in SA and now I am in Greece. I cannot download free apps as I get a message that the apps are not available in the SA store and only in US stores. When I change to the US store the same thing happens. What is the point of having an iPad if I cannot use it worldwide??? I feel that I wasted my money purchasing it as I specifically purchased it to use when I travel. How can I get access to all the available apps and why are they restricted.

You can use your iPad worldwide. However, each AppleID is tied to
a specific country's store. To use the AppStore in any country, you
must be in that country and have a credit/debit card issued by a financial
institution in that country with a verified billing address in that country.
It is the developer's choice which AppStores he makes his app available
from, and some countries prohibit certain apps.
To make a purchase from the US store (including downloading a free app
available in the US store), you must be in the US and have card issued
in the US with verified billing address in the US.
You can use your purchases from the SA store worldwide, but you
cannot make purchases in other than the SA store unless you meet
the aforesaid conditions.

Can I use my Time Capsule with a point to point antenna?

We have a building about 400 feet away that I would like to install wireless cameras. Can I use a point to point antenna with our time capsule or is there a better option?

The Time Capsule is too hard to get into. You can do this but the end result will be rather messy and for an expensive unit like the TC that is a waste.
Get a unit made for this job.. you only need a WAP..

IPv6 Addressing Point to Point Links in the enterprise

For an enterprise, it doesn't seem to make sense to use Global addressing for point to point, transit-only links and loopbacks.
Link-local only addressing breaks debugging tools like traceroute, DNS, etc.
Is Unique Local the correct choice for this?
I've searched quite a bit and I've not found a lot of discussion about scope selection for point to point links. Some RFCs such as 6164 imply Global scope vs Unique Local scope usage is a preference. Most discussions of point to point addressing focus on bit length. I'm assuming this means design concerns are agnostic toward scope selection.
Is anyone aware of documentation I've missed or have any recommendations in this area?
If ULA was the correct choice, address hierarchy might look like this:
DataNetwork1 -- Router1 -- ULA.1.1 -- Link -- ULA1.2 -- Agg Router -- Core
DataNetwork2 -- Router2 -- ULA.2.1 -- Link -- ULA2.2 -- Agg Router /
DataNetwork3 -- Router3 -- ULA.3.1 -- Link -- ULA3.2 -- Agg Router /
The network core would have summarized entries for DataNetwork[1|2|3] and ULA[1|2|3]. IE, there would be a Global hierarchy and a ULA hierarchy.

Scott,
Let me break this down into some categories for you.
Address selection:
I believe that best practice is to use Global Unicast Addressing everywhere (coupled with a proper security policy at your edge). ULA was a compromise for Site Local never being properly defined and whilst it can be used in the same way as GUA I don't believe it is worth it. Irrespective of what you use (GUA or ULA), subject to your security and routing policy traceroute will work from both ends (e.g. you tracing out, someone tracing in)
Address masking:
The general rule of thumb is that you allocate /64s to eveything and then mask down to the appropriate mask for the function you are expecting (P.S. Forget everything you learnt about IPv4 address conservation). If you are using /127 masks then in theory every p2p link in your network is either a 0 (::) or a 1 (::1)
e.g.
traceroute HostB:
1     2001:1234:abcd:1::1
2     2001:1234:abcd:2::1
3     2001:1234:abcd:3::1
4     2001::4:10
The only exception to this is loopbacks, you can sequentially allocate /128s from the same /64 block
NOTE: /127 support is recent and may not be supported by some vendors, in this case use /126 masking (same as you would use /30s in IPv4)
If you have a /48 ( a normal enterise allocation) or larger then this should not be an issue ( you have access to 65536 x /64s) the only reason you would consider ULA for infrastructure numbering is because you have a small IPv6 pool. I would still argue you should get more IPv6 addresses than use ULA.
I hope this helps
Cheers

Turns out the mistake was not adding a mask to the subnet. Ex:
Router_2(config_router)# network 192.168.0.0 0.0.255.255
Router_2(config_router)# network 172.27.0.0 0.0.255.255
Doing that on both routers made the hosts capable of pinging each other.
Thanks for the tips everyone

How do I get routing data from the Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application.

I have a tableView displaying a list of contacts from a Cloud Database. After selecting a contact, I push to a programmatically created MKMapView. Then I display the initial region (the view) that includes the users current location (starting point) and their selected destination (end point).
Now I want to display annotations (as described in the Location Awareness Programming Guide) that displays polylines which will represent the turn-by-turn navigation IN MY OWN APPLICATION, and not in the Map App currently used in IOS6.
Due to licensing and its becoming depricated in IOS 6, I do not want to get routing data from the Google Maps API. How do I get routing data from the IOS 6 Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application?
I checked out Stack Overflow and other forums which basically left me with the impression that this is not possible. I also checked out the TomTom iPhone Mobile SDK User Guide from the TomTom Developer Portal and am still confused. It must be possible to retrieve routes, since the Map App can display turn-by-turn directions. How can I retrieve turn-by-turn data that I may display as a route within my own application?

Thanks Michael. Apologies for the slow reply I was away for a bit (holiday blitz at work and visiting family madness etc.etc.) back now, I set both options you requested to "never " and retried the CMS software with no change.
I do have progress of a sort though, as a test I took a separate test PC and put a clean install of Win7 on and loaded up the CMS software (it worked perfectly) and then took the version of ole32.dll off that machine and put it onto the computer I had built
for her (using Linux) and...
got a new error code. Darn I was so sure I had found a clever solution this time lol.
Anyway now when the CMS fails it gives me a similar error but the offending module is "ntdll.dll" sooo... I tried taking the "working" version of ntdll.dll from the test box and moving it over (making sure to back up the existing ones
first so I could put them back if needed) to her new PC and the PC would not boot.
It seems to want the original versions of a few Dynamic Link Libraries and if I could somehow give it those while not breaking Win7 it should theoretically work seeing as it no longer errors with ole32.dll.
ntdll.dll however seems necessary for Win7 to boot.
So what I am wondering now is:
Is there some way to have both versions of the DLL file in the system32 folder (bypassing the "cannot have two files with the exact same name in the same folder" thing) or rename the original DLL's something else and somehow make the CMS look for
the new named versions so the system has the updated DLL's it needs to boot/run and the CMS has the old ones it wants to run or is there someway to have a self contained install of the CMS, say on a USB flash drive and give it it's own E:/windows/system32/needed
dll's path to the files it needs?
Willing to try any other options or settings you may have come up with as well.
Thanks again for your reply and my apologies for not answering sooner.

Broadcast and point to point server in the same port

I'm trying to set up a system where I can send point to point messages via sockets to certain ips, send broadcast messages to every pc in the network, and also be able to listen for point to point messages and broadcast messages, all in the same port. I've been able to establish a point to point connection using the Socket class to send the message, and using the ServerSocket class to listen for messages, but I can't seem to get broadcasting to work.
I read somewhere that for broadcasting one should use the DatagramSocket class. The problem is i'm not sure which ip i'm supposed to specify when I send the message. Also, do I need a special listener to listen for broadcast messages, or will the ServerSocket listener work for that?
This is what I have for the broadcasting part:
String msg = myId;
DatagramSocket sendSocket;
sendSocket = new DatagramSocket(Constants.COM_PORT); // 4567
InetAddress group = InetAddress.getByName(Constants.BROADCAST_ADDR); // "192.168.1.1"
DatagramPacket dp = new DatagramPacket(msg.getBytes(), msg.getBytes().length, group, Constants.COM_PORT);
sendSocket.send(dp);
sendSocket.close();
Thanks in advance
Diego

It worth mentioning that UDP/broadcast and robust do go together easily.
- UDP does not guarantee delivery. i.e. messages can be dropped and you won't be told. Lost packets are not retransmitted either.
- UDP can fragment packets if larger than 532 bytes long.
- UDP packets can arrive out of order (though I have never seen this myself)
If your receiver is under load/busy it can miss many packets if its buffers overflow.

Calculating BPM using either Peak Detection point by point or FFT

Hi Guys
Im new to Labview and have absolutely no idea on programming and stuff. Im doing a project on Heart Rate monitor.
I'm using labview to read the analog input to an Arduino Mini. In my attached VI im using Peak Detection Point by point to calculate the BPM but it doesnt seem to work. I took references from several VIs to arrive at my VI.
My instructor told me I could try using FFT to calculate the BPM as well but Im not sure how to carry it out in Labview.
Hope you guys can help me with this.
Thanks alot!

Ok, we have some problems here.
1. The Data Bits property is the number bits for a single character that is being transmitted. You should not use that. Since you are using an Arduino, it should be sending the termination character. So just tell the VISA Read to read maximum number of bytes you expect from a single message or just some large number (like 25). The VISA Read will stop reading the port when it encounters the termination character.
2. The String Subset is not doing anything. Just remove it.
3. You should move your Wait to be outside of the case structure. As is currently written, if you are not taking readings you will use up all of your CPU.
4. You should have labels for all of your controls and indicators.
5. Your time calculation is completely wrong. You want to subtract the time of the previous peak from the current peak. I recommend you use a Feedback Node to do this.
Here's a slightly cleaned up version of your code.

XY graph : Plot point by point

hi my intention is to plot in a XY graph point by point. Meaning for eg: I want to plot a scatter plot.
First I check if the array element satisfies a certain condition (let's say if it lies between 1 to 5) if So I want to plot in red color, else I want to check another condition (let's say lies between 5 to 10) and then plot in blue color and so on.
First I check for the condition and link it to a case structure such that each case structure will contain the corresponding plot color but it doesnt seem to be working.
Kindly guide me with this.
thanks!!
Solved!

Hi Chathuri,
If you want to plot a scatter plot, you can do this by editing the properties of the XY graph. Righ-click on the X-Y Graph object and click on Properties.This will bring up the property viewer. If you then go to the Plots tab, you should see a screen similar to the one shown as an attachement. The fourth column from the left sets the display type and if you click the top diagram, you will display individual data points. I have circled this in the attached diagram. You will also need to set the tick markers to display. You can do this if you set the third column from the left.
Hope this helps,
