WAN Optimization techniques
Posted on 2010-08-15
Our network consists of a 300Mbps Fiber Uplink connected to a Cisco Catalyst 4560 (Our Gateway to the provider) and about 150 servers on the network.
Our network utilization usually sits around 150Mbps to 220Mbps (Peak hours)
The issue we are experiencing is extremely poor file download speeds (Download Link or FTP)
At most these days what I'm able to get in 1 file download is about 600KBps (I'm testing with a 25Mbps connection I have at home and a few 100Mbps connections we have in branch offices. At most we'll get is about 1MBps.
I spoke with the ISP about this and we did an Iperf test and by spawning several connection we are able to aggregate 60+ Mbps but what I'm looking for is better performance for that 1 file download (HTTP) and so forth.
I'm just wondering if there is anything I can do with my cisco catalyst to improve performance (QOS) and any other options I may have.
Any help would be greatly appreciated (Please be as specific as possible) I'm a little lost right now.
I looked over WAN optimization appliances but it seems these need to be setup on 2 end-points over a wan in order to work (not going to work for us).
Hope you can help,
