Our company is starting centralize applications in a data-center in Chicago, IL. One of them includes an application that utilizes Citrix as well as Windows file copying.
The branch sites rely this data-center for applications and file services.
One of the branch sites is located in LA, California. Our company uses MPLS as WAN connectivity. The Chicago site has a 45mbps DS3 into the MPLS WAN and LA has a 9mb into it. The round-trip latency is about 68 ms. Average bandwidth utilization is about 15% for each site.
We've begun user testing in LA and noticed some unsatifactory Citrix login times and Windows file copies from the servers in the midwest. It looks as if the WAN bandwidth isn't getting completely utilized during the tcp connections for these activities.
The server group is looking at optimizing TCP on the systems. The network engineer (me) is validating WAN circuits and bandwidth allocation.
Is WAAS something to consider in this scenario?
I've read Citrix/Cisco white-papers . It seems to match our scenario. We are a finanical company.
Thanks for your help
