MB - NG Some Edge (Bbone) Router requirements Connect to the test systems in the IP domain. Accept marked packets and be able to re-mark them Mark the packets on input according to at least: Source – dest IP address IP port Layer3 and Layer4 headers TCP/UDP Support Diffserve code points Perform policing and admission control Provide a range of Queue type options – Several queues with different priorities Real-time queue Provide flexible Queue Scheduling Weighted round robin Weighted fair queuing Provide Congestion control such as RED ECN Be able to assign MPLS labels to the packets in a flexible manner.
