Transcript Hardware Requirements and Diagrams

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.

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
