Does anyone know what queuing method (and buffer size) Procera (or Sandvine or Saisei, etc.) use?
I remember asking Procera at a show 1-2 years ago if they had programmable queue depth and the answer seemed to be no. I was thinking they could implement traffic shaping rather than policing, but it didn’t sound like it. I ask for 2 reasons. The downstream network wouldn’t need to handle the bursts, since they would be smoothed out. And I suspect some of these misbehaving CDN servers are ignoring packet drops as a congestion indication unless accompanied by increased round trip latency indicating buffer fill. The rate limiting methods we use currently on our routers don’t introduce much delay, and some of the CDNs don’t seem to implement congestion avoidance until the packet drop rate hits about 45%.

Even some towers where we have shelter space, I can’t guarantee the temperature specs they want.

My box which can do a gig of traffic cost $18,000 with the first year of signature updates and it is like $2500 annually after that.

If you want to do some shaping on an application like only streaming or Windows Updates and stuff like that then that's where things start to get expensive. I am using the Procera myself for that and although I havn't tried any of the other brands you mention I am very happy with the Procera.

I have a list of vendors/products a have assembled over time that I was going to look into: Saisei NetEqualizer Packeteer (Bluecoat) NetEnforcer (Allot) Network Composer (Cymphonix) Exinda Anyone care to share experiences on this subject?
