WAN Help

By jparedes1999 ·
We have implemented a WAN Solution for our 2 offices using Cisco Routers & US Sprint Frame dedicated lines. Problem is users are getting bogged down trying to access server files across the frame cloud. Is increase bandwith a good solution ?

thanks

Some things to look at

by radiic In reply to WAN Help

1st. Check your contract with sprint and find out what your CIR is. Committed Information Rate. Usually they only commit to about half of the bandwidth you purchased. This can mean Alot. Ihave a 128k frame with them but they only guarentee that Iwill have above a 64k transmission rate. They are right my throughput has ranged from low 70k's to high 90k's. I use NetIQ check http://www.qcheck.net Increasing your B/W will help but the cost is up to you.

2nd Are you using hubs or switches on each side. You will see some performance value there by using switches (L2)

3rd. Make sure your routers are setup properly. A weird setting like MTU=600 instead of MTU=1500 can kill you.

Other than that, Your stuck with your current performance. Maybe its time to look into having workgroup servers. (One on each side of the wan) That way there not accessing files accross the link.

Good Luck

Terminal Server is an option

by gcwoods In reply to WAN Help

Have you thought of using Terminal server across the WAN, it has low bandwidth usage, but you'll need WIN 2 K or NT Terminal Server to do this.

WAN Woes

by jgraham In reply to WAN Help

1. First are you using seperate Sub-Nets on either end?
Try using something like 172.16.8.1 subnet 255.255.252.2 on one end and 172.16.12.2 255.255.252.0 on the other.
This will help 2 fold:
A. No hunting for DHCP Server and renew traffic B. No Broadcast traffic over that slow WAN Link

2. Make sure you have a BDC at the other end

3. Use WINS for name resolution and setup replication

4. Make sure you infastructure is setup properly.
A. Where is you default Gateway? B. If you have an Internet route and it is the Default .. Plug the FRAME link into that router. This will help packets NOT to travel your Network Backbone twice.
