you're going to see more of it, at a minimum cpe are going to have to be able to drain a gig-e into a port that may be only 100Mb/s. The QOS options available in a ~$100 cpe router are adequate for the basic purpose. d-link dir-825 or 665 are examples of such devices > Personally I have MQC configured on my interface which has assured bw > for small packets and ssh packets, and I also run fair-queue to make tcp > sessions get a fair share.
