  1. MB-NG Managed Bandwidth Project On the SuperJANET4 Development Network Richard Hughes-Jones The University of Manchester Particle Physics Network Coordination Group SEQUIN Workshop Amsterdam 1 Feb 2002

  2. UK E-science core project • Project to investigate and pilot: • end-to-end traffic engineering and management over multiple administrative domains – MPLS in core diffserv at the edges. • Managed bandwidth and Quality-of-Service provision. (Robin Tasker) • High performance high bandwidth data transfers. (Richard HJ) • Partners:CISCO, CLRC, Manchester, UCL, UKERNA plus Lancaster and Southampton (IPv6) • Would like to use real Grid traffic – as demonstrator: • CDF UCL-RAL • BaBar Man-RAL • Demonstrate end-to-end Network Services • To CERN using Dante • To the US – DataTAG • Monitoring – DataGrid e2e latency /rtt / UDP and TCP BW SEQUIN Workshop Amsterdam 1 Feb 2002 R.

  4. QoS Investigations • Implementing MPLS/QoS at a domain Boundary • Define traffic classes and policies for the domains • Classify packets on input – Diffserve: Source – dest IP address IP port • Perform policing and admission control • Provide 3 Queue types: • IP Premium - EF (Real-time queue eg Strict Priority) • Best efforts - BE • Less than best efforts –LBE (Scavenger QBSS) • Provide flexible Queue Scheduling – WRR • Provide Congestion control RED WRED – ECN • Implementing MPLS/QoS within a domain • Switching / routing on the basis of MPLS labels • Perform policing and admission control • Provide Queuing and Scheduling based on MPLS label • Be able to re-label the MPLS packets in a flexible manner. SEQUIN Workshop Amsterdam 1 Feb 2002 R. Hughes-Jones Manchester

  5. High Performance High Throughput • Bringing Gigabit throughput to the Grid applications • Show and tell demos • TCP streams operating at Gigabit rates • GridFTP operation • 100 Mbit, 500Mbit, 1 Gbit long transfers • Investigate • Understanding the operation of the end system HW • PCI Bus load CPU and OS • How to monitor protocols at Gigabit rates • Test and background traffic patterns • Measure • Latency • UDP and TCP Throughput – Different TCP algorithms • Packet loss • Packet jitter – IPDV • Non TCP transports SEQUIN Workshop Amsterdam 1 Feb 2002 R. Hughes-Jones Manchester

  6. Project Status • Funding • Approved: Equipment, 3 posts: ULCC UCL Manc. + Support for RAL staff • Will Start on 1st Appointment • Core Network • 2.5Gbit Fibres ready • GSRs + Gig Ethernet Delivered, POS blades to be ordered • Expect to connect 2.5Gbit POS fibres to routers by end of June. • Access Links • CPoP – Manc upgrade to10Gbit circuits – expect Jun 02 • Lon CPoP – ULCC link being used for US access - will be free in 1-2 months • ULCC-UCL – UCL fibre – expect after Easter • RAL – dark fibre – will be lit when required SEQUIN Workshop Amsterdam 1 Feb 2002 R.
