Hospital Network Infrastructure

Hello,
I need to gather some general information about network infrastructure in hospital. Things like which network devices we need and generally how much load each department creates in our network (e.g. the operation room, the reception, etc.) and how much bandwidth we should allocate to that special room. It would be alo very nice if you tell me how I can calculate the load for each machine (i.e. computer connected to the network). Or any good reference books or websites.
Thank you very much,
Pat

how much bandwidth we should allocate to that special room
I'm no expert with hospital environment but we've started rolling out Gig ports switches with PoE+ support and 10Gb uplinks to the hospitals here. Some of the reasons are the uptake of video streaming and high definition media files that are coming online. Gone were the days when you have to physically look at x-ray templates on in front of a lighted cubicle. Nowadays the films and negatives (ranging from x-ray, ultra-sound, MRI, etc.) are stored in a bank of servers and streamed up to desktop.
Due to the proliferation of wireless we now have to consider putting wireless access points and associated support equipments (WLC/WiSM, WCS, MSE, Wireless VoIP phones and RFID tags).
Due to the nature of hospitals, our switches comprise of 3750E and 3750X with 6500 and Sup720.

New Network Infrastructure Design and Architecture Community

All,
I'm pleased to announce our new Network Infrastructure Design and Architecture Community. In this community we encourage everyone to share their knowledge and start conversations on design and overall network topology. All topics are welcome, including requirements and constraints of the network, tools and techniques, issues of hierarchy, leading practices, services, build strategies, architectures and solutions to solve business problems.
Who will be the first to make it on that leaderboard?
Cheers,
Dan

Mike,
Thanks for the kind words about the community. It's always nice to hear the things we do make a difference.
Launching a scripting community has come up a few times in the past and I'm open to it. Anyone else have thoughts on this?
On a separate note, you'll be thrilled to hear what one of our CSC booth give-aways will be at Cisco Live San Diego next week. Your best friend the cross-over-cable    For those of you out there attending the event be sure and stop by the CSC booth.

I am trying to set up my apple tv using the hospital network. I am able to detect the network and chose it. But the way the system works is that you have to agree to the terms and conditions of using their network before access the internet. How do I accomplish this with apple? Please help.

There are some other options to you, if you're not at home and nobody is using your router you could set it up at the hospital, if this isn't an option you could get a second router and use it. Many ethernet routers are available on the cheap, and ethernet cables are cheap too.
Also, a macbook can share it's internet via the built in wifi it has. See this go to settings-sharing-internet sharing and configure as desired. This may require an internet connection via ethernet. But you should be able to create a wifi network for using something like airplay/home sharing.

Howto test new or modified network infrastructures with standardized testing methods?

Hi,
I'm sure many of you regularly do tests of new or modified network infrastructures before going live. And you developed detailed plans and schedules how to test, how I did too.
Does anybody know if there exist standardized testing methods for this cases?
Like recommendations how to check features, performance, hardware failures, convergence times, software updates, network management etc.?
Does Cisco offer information concerning that?
Especially for software testing there exist many methods to check if it's working properly, but for technical it infrastructures I did not find any informations.
Best Regards
Thorsten

I guess you are looking for something like this -
http://www.ciscopress.com/store/enterprise-network-testing-testing-throughout-the-network-9781587141270
should say I don't own the book or have ever read it.
I have never come across a set of standardised testing methods in the same way software has but that's is not particularly surprising when you consider networking as an industry is a long way behind other parts of IT in that respect.
We are all still using CLI for most of our jobs :-)
I suspect with SDN that there will be a far more extensive range of testing tools available in the long run but we aren't there yet.
Personally I do pretty much what you already have. When I was involved in design we had proof of concept labs where we could test it would actually work and which often fed back into the design.
Then we had to test it with the existing production environment to see how it impacted on what we already had.
If all that went well we then pretty much knew what tests we needed to run when we implemented it into production.

What will be tomorrows network infrastructure?

Due to historical reasons, many different network infrastructures co-exist in today's networks, such as Ethernet, SONET, ATM, etc. However, if we are building a complete new infrastructure for a metro or large campus network, which technology would be the most appropriate? What is Cisco Experts opinion?

I would answer this question differently if I were considering the use of the network to be a service providers network or an enterprise network in that I could achieve a different cost model based on single versus multiple customers on the same networks. Also, the end needs of each customer are different, and if they were completely defined could lead to a different cost model for the services rendered.
Generally, a service providers network requires support for TDM and data protocols, requires stringent Service Level Agreements, and generally either owns their own or has a lower cost per mile for fiber than an enterprise. For this reason, a SONET/SDH based network with data capabilities provides the most cost effective way to transport the variety of circuits and streams from the end users location to the point-of-presence (POP) and a WDM system based network is used for the long haul and inter-POP traffic is used. Data can be Ethernet over SONET/SDH or WDM, or it can be done with RPR (802.17).
The enterprise is usually seen as more fiber constrained, and therefore uses a metro WDM (Coarse or Dense) to transport SAN and Ethernet connections between buildings. The ability for the enterprise to convert most legacy traffic into Ethernet, and the ability to combine Ethernet ports into ever-larger trunk speeds, can also lead to very cost effective Ethernet over dark fiber networks up to the new 10 Gigabit per second standard. RPR systems can also be used to extend SONET/SDH recovery mechanisms to Layer 2 and 3 networks.
With voice and video moving to native IP, and the ability to tunnel most other legacy traffic over IP, Metro Ethernet systems over dark fiber, or extended over WDM or SONET/SDH systems are beginning to be the most cost effective way for businesses to connect within the campus or metro today.
The question we have to ask whenever we build a network is what will the next 10 years bring us. My vision is one of lots of devices with wireless mobility, the mixing of SIP and HTTP services to the mobile devices, and lots of high speed Global Area Networking overhead to figure out who and where you are. What is your vision of the traffic and protocols you will be required to support in ten years?

Network infrastructure

HI, I am a person that response to build a network infrastructure in a company. I want to design a good network with high security.
I have a host server (Dell power edge RAM 16)
I want to ADDS, File Server, and Antivirus Server.
How can I user this server in effectively?
Can I user Hyper-V or put the three server together?

Hi,
Microsoft does not recommend installing roles - Hyper-V, File server, AD, DNS roles in a physical server.
Instead you can install only the Hyper-V role on the host and virtualize all of the other roles (DC, DNS, File, etc.).

Airtunes on hospital network

Have been trying to do this: Can get on the internet with a wireless hospital network using my Powerbook G4. I would like to stream music from my Powerbook G4 to an Airport Express hooked up to an Operating Room Stereo. Have tried all types of set-ups but it doesn't work. Any ideas? Can I be on two networks at the same time?

Ben,
Yes and No.
No, I don't think you can be on two wireless networks at once.
But Yes, an idea, you should be able to make the AE a wireless client, connected to the hospital wireless network. Then you stream music from the PBG4 to the hospital wireless network and it transmits it on to the AE.
The option to make the AE a wireless client is an option in the Airport Admin Utility. Remember to turn on Airtunes at the same time.

OCS hardware/Network Infrastructure Requirements

Hi,
I was wondering whether anyone was willing to share their current network infrastructure for their OCS deployments.
In terms of type and specs of network cards used by the OCS servers that host the applications?
In addition to this I was wondering whether anyone has used the same windows server to host the web conferencing and voice/fax options or perhaps if this is possible.

E1000 device name in Network Infrastructure

Hi all,
I installed the E1000 router that AT&T provides with U-verse DSL. All works fine except that the device name that appears under "Network Infrastructure" in Windows 7 shows the original default name that Cisco assigned instead of the name I chose. It does not affect operation or performance but looks oddball. I don't see how it can be changed. Does anyone know?
Thanks,

For the E4200, on the Basic Setup page, there's an entry called "Device Name" that I changed from Cisco07933 to E4200. So that's what I see when I look at "Network" on my Windows 7 system. You might have the same or similar setting for your E1000.

Designing Network Infrastructure

Hi,
I am working on a project to design and implement new data center infrastructure Also migrate users from the old network . The current setup is that network has several vlans and each switch is connected to the main switch via fibre. The new network infrastructure will have two core switches 6509, several 4500 series switches for wiring closet and 3750 switches where the devices will be connected. 4500 switch will be connected to both core switches 6509 via fibre. In this situation, what will be the proper network design? Will appreciate any thoughts.
Thanks

through ur discription i havnt heard from u any thing about the ditribution layer!!
u need the distribution layer befor the core layer
in other words
it should be like
access switches-- distribution --core
basicaly
on the access layer creat all the required vlans but keep them on lyer two
dont make and vlan interface
on the distribution layer
creat the same vlans here layer two
and then creat a vlan interface SVI fopr each vlan
and this vlan interface will be the default gateway for the access switches in the corsponding vlan
next if u want or and u see it required make a core layer
while i think u dont need it
in ur case the distibution layer will be called
distribution/core layer
the link between the access switches and the dist. switches must be trunk
if u want redundancy and high availabilty
u need two dist switches with identical config to some extend
i mean the ip addresing not meant to be the same but in the same ranges with regard to each vlan
and configure hsrp on the dist switches
in the case the default gateway for each vlan access layer user will be the vertiual interface of that vlan hsrp group
also u have to make the active switch in the hsrp group the root switch in the spanning tree config
for dhcp make the ip helper address on each SVI on the dist. switching pointing to a dhcp server and useing the proper VIP for that vlan group as the default gateway
and add the
spanning-tree portfast on each access port that will be a dhcp client
good luck

Help : Network Infrastructure in a Retail organization (Set-up)

Dear All,
Ok . So this is more of a broad question - but please I need possible idea on how to solve my problem. I haven’t done this before so its more of a high level.
The SITUATION
Ok so theres one established site Company A., (a retail company) in New York, they have all the AD, Exchange ,VPN and all set up. Now they have planned to set up another company B in Texas. This new site would have its own domain
name but they want it to share resources with company A. Ok so these are two different locations.
The QUESTION
Now my question is , in terms of Networking – how would I be able to link these two sites together since they are in different locations(of course I can’t run a fiber OP cable from New york to Texas)
Secondly what would the relationship in terms of domain link? Would it be just trust?
Many thanks all im open to any hint please.
Regards, MassonTech

Hi,
Question 1：how would I be able to link these two sites together since they are in different locations.
I suggest you to use site-to-site VPN connections, such as dial-up line uses short-distance WAN links to your local Internet service provider (ISP) instead of expensive long-distance WAN links. You may reference the link below for detailed information about:
Implementing a Site-to-Site Connection Design:

Branch Office over the Internet：
http://technet.microsoft.com/en-us/library/cc736396(v=ws.10).aspx
question 2: what would the relationship in terms of domain link? Would it be just trust?
If these 2 sites are belongs to different domains, there is a need to create trusts between 2 domains to share resources.

Eve Wang

Network infrastructure review - how to differentiate between network consultants?

Not sure this is the most appropriate forum to discuss as its not a Cisco product technical question per se but thought i'd give it a go anyway in case others have been through similar and can give some input.
Following recent mergers, acquisitions etc my company would like carry out a network review to find a recommended overall architecture/strategy moving forward. We have engaged with a number of different consultancies keen to assist us with this.
The problem is - what should we be asking/checking to help differentiate between these consultancies and select the best one for the job? They all "talk a good game" and can boast of CCIE accreditations in their teams etc - so what should we be doing to make sure we select the right people? (Cheapest does not always mean best!)
One thing we are keen on is that we only want them to carry out a review and give us recommendations - its not a mandate for them to actually sell us specific products and services following the review.
Any thoughts on this from forum members?

Thanks for the response.
It’s not so much finding a Cisco partner that’s the problem, it’s differentiating between them. If we talk to two different Cisco partners, then each can boast of CCIE engineers and give references from satisfied customers etc. Each will also have different timescales and pricing associated with them – is there any way we can differentiate between them to ascertain which one would be best for the job at hand or – if they have the same level of accreditation etc – should we simply go with the cheapest/quickest?

Network Infrastructure ISP questions

Question, trying to understand. Scenario. Have one isp with 72.54.180.162/30 network isp router to our main site router. Need another block of public addresses from ISP to assign to tenants on different floors, let’s say that block is 63.250.250.32/27. The tenants NEED static addresses. This is hypothetical situation I am trying to understand. See attachment for network map.
So, two questions here:
How does the isp get you that second block of addresses? Do they just create a sub interface on their router for additional block? I mean I know you can create sub networks on the interfaces but that would not allow you to subnet out the second ip block to be used for the tenants, correct? I know you could add a layer 2 device between isp and main site router and directly plug in tenants there, but let’s assume there isn’t a layer 2 device. I just want to know what the configs would need to be on the main site router and the isp router to allow that second network to be used for the tenants.
If subnetting the 63.250.250.32/27 to /29 I created 4 subnets, where they can be used for the four tenants listed below. I would assume that I need VLANS in order to prevent one tenant from assigning an ip from another tenants subnet?

Hi bboklewski,
See my responses below:
1. I'm an ISP, I have single connection with customer. Customer needs more IP addresses. I just create a static: "ip route 63.250.250.32 255.255.255.224 <you side of p2p>" I probably already have a redistribution policy for statics, I just add that into my prefix list and its goes up. You your main site router, you just need to add routing toward your tenant's next hops. Otherwise, if you use BGP, then you announce this new prefix like any other prefix...and insure you have routing toward your tenant's devices.
2. Yes. You need 4 VLANs if you need segmentation between tenants. What happens when your tenants need more IP addresses? If your ISP gives you IP space, then they do the static routing as outlined in 1. You then add a secondary IP address on your main site router's interface facing the tenants--the tenants deal with further routing. If you get your own IP space, then same thing applies, except with a BGP configuration as outlined in 1.

Network infrastructure projects.

I don't know whether it is appropriate to post in this forum
Neither i'm a computer nor telecommunication network savy.. before consulting different company marketing executive, i would like to have a glimpse of required latest technology and infrastuctrure in connectivity..
Here is my point.. A few hundred miles from my province there is international underwater cable landing station.. there is to a proposed project to connect this landing station with ofc and create regional NOC which will be able to upgrade into future internet exchange and IIG.
With cisco system what will be the most appropriate require machines and equipments (Router, Switch, firewall etc..) to establish regional core network infrastucture under 1gbps connectivity... i'll be very glad if i could get comment with picuture diagram... thanks..

Pls contact the respective Cisco AM or your Cisco PAM . They will be more than glad to assist you .
Thanks.

Network infrastructure planning advice

I need to set up a new network: "Network A". It needs to have a t1 to "Network B", a backup t1 to "Network B", and a t1 to "Network C". In the near term future there will be a T1 to "Network C" and a T1 to "Network D".
What is a good router configuration for "Network A"? How many routers? What models? What T1s to what routers?
thanks

In addition to ur stated requirements, I would also wish to know what type of connections(Long time, short time) and what is going to be the distance b/w ur Network A and other networks?
Here r the two main WAN connection :
1.For short Distances and long connection times - Leased line is far better.
2.If u want to use shared bandwidth and more efficient packet switching and for Long distances(Long connection times) - frame-relay is good.
Both these technologies provide more than T1 (1.544 mbps) speed connectivity.
Since, u need a T1 backup, ISDN PRI provides this T1 speed connectivity and so u can use it as backup line.It is a circuit switched n/w.
