  1. 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.

  4. Some Notes • RAL/UKERNA provide access to real Grid data e.g. BaBar HEP data • Advantages of the Proposed configuration • Three MPLS Administrative domains available for tests • Uniformity of blades, interfaces and software • PXF on the blades provides for more options & future developments • MPLS based MANs would use these blades • Provision for foreseen upgrade of the OSM blades should be included • Background traffic (non-MPLS) can be injected via: • 2 Gigabit Ethernet interfaces on the Supervisor card • 4 Gigabit Ethernet interfaces on the OSM POS cards • ECN not yet available on any blades – could be experimental later • Traffic on the OSM WAN ports cannot be monitored (span) in the router • Use of external CISCO 3508s • Traffic on Supervisor ports may be monitored • Use of header monitor on backplane MB-NG Jan 2002 R.
