Choosing a Traffic Prioritization Method
After separating interactive and batch traffic into individual streams, a prioritization method needs to be chosen. Cisco IOS software has a large and growing list of prioritization options, including priority queuing (PQ), custom queuing (CQ), weighted fair queuing (WFQ), and weighted random early detection (WRED). Prioritization methods collectively can be called queuing methods, output queuing, or fancy queuing. One important factor that is often overlooked is that there must be congestion...
Opening Multiple DLSw Ports
The first step in separating traffic on different flows is to create the flows on which to put the traffic. This is done by adding the priority keyword on the dlsw remote-peer command as follows dlsw remote-peer 0 tcp 1.1.1.1 priority The priority keyword instructs DLSw+ to open four sessions to the remote peers on ports 2065, 1983, 1982, and 1981. By convention alone, these ports are given names high, normal, medium, and low. This convention is not widely known, but it is critical to...
