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

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.

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

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 12 months
 ULCC-UCL – UCL fibre – expect after Easter
 RAL – dark fibre – will be lit when required
