"I can do the traffic prioritization on my routers (3com) but it's a bit of a pain and frankly if I could do it more easily on an appliance then I would." OK, that answers the question I have not asked yet ... QOS in addition to handshake latency reduction should get you *most* of the way there ... but if HTTPS is hogging your bandwidth, can you identify what is occuring within ? Is it SSL to web pages, or SSL based VPN. And 15 years ago I was in on some training for a new version of IP that has compression ( among other features ) built-in ... so what happened to IPv6 ??? <g>

For data, RDP to our terminal servers first here at, http traffic last. Statistics show that during the day https traffic hogs the pipe and users complain of slow downs with our other systems. 2. compression of traffic. I know the appliances can only compress "known" traffic such as smtp, http, etc. So I'd need to know from the vendors what sort of traffic is recognized and what sort of traffic can be compressed/optimized. I can do the traffic prioritization on my routers (3com) but it's a bit of a pain and frankly if I could do it more easily on an appliance then I would. I'd rather go with a management device than bump up my point to point, which would cost more in the long run.

Most WAN Optimizers cache the data stream and remove most of the windowing/handshaking to reduce the latency ... so your data streams to the destination without two way delays of 'got that segment, what's the next segment , got that next segment, what's next now' type of protocols Erik Goldoff IT Consultant Systems, Networks, & Security _____ From: Tom Miller [mailto:[email protected]] Sent: Tuesday, May 26, 2009 12:49 PM To: NT System Admin Issues Subject: Wan optimizer I've seen occasional talk about bandwidth management/compression. I'm looking for an appliance that can do this between my HQ site and second largest site. Anyone have any experience/recommendations. The two I am familiar with are Citrix's WANOptimizer and Packeteer (now Blue Coat).
