MB - NG MB-NG Jan 2002 R. Hughes-Jones Manchester 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.

MB - NG MB-NG Jan 2002 R. Hughes-Jones Manchester 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
