Framework for Proposed TE and QoS Tests - Project Deliverables - * To demonstrate end-to-end traffic management across multiple domains using live Grid traffic (TM2) To demonstrate end-to-end QoS and traffic management between the UK and USA (TM3) To demonstrate end-to-end QoS and traffic management to CERN (TM4) - e-2-e services - separate administrative domains - diffserv, “other” packet marking, TE etc * To understand the use of MPLS as a traffic engineering tool within the CORE SJDN (TM1) - understanding of MPLS - as a basis to configure traffic management for “guaranteed” bandwidth and QoS

Framework for Proposed TE and QoS Tests (1) - Broad Work Areas - Using the defined test traffic The proposed framework falls into two broad areas, 1. Policy-based tests, 1. With and without MPLS using Basic packet marking techniques, i.e. using diffserv and QBSS across the extended SJ4/MG-NG test network; 2. Bandwidth broker developments using Expect scripts to make real-time adjustments to router configurations, i.e. policy mapped to scripts leads to router/network reconfig’s. (see work done an U Michigan in this area) 2. Cisco guaranteed b/w developments using MPLS/diffserv/rsvp to model the VPN

Basic Packet Marking Tests - Configuration -

Basic Packet Marking Tests - Test Proposals (1) - For testing between, for example, Manchester and UCL and for each specified Policy - P(C), P(M1), P(M2), P(M3), without MPLS enabled in AD(C), and with MPLS enabled in AD(C) the following configurations are required for, 1. diffserv tests 1. diffserv operation in AD(C) only, and 2. diffserv operation in AD(C) plus AD(M1) and AD(M3) 2. QBSS tests 1. QBSS operation in AD(C) only, and 2. QBSS operation in AD(C) plus AD(M1) and AD(M3)

Basic Packet Marking Tests - Test Proposals (2) - For the test data flows where, for example, Manchester to UCL is being tested, Man -> UCL; Man -> UCL; RAL -> UCL; Man -> UCL; RAL -> Man; Man -> UCL; RAL -> UCL; RAL -> Man; Man->UCL; UCL -> Man; Man->UCL; UCL -> Man; RAL -> UCL; Man->UCL; UCL -> Man; RAL -> Man; Man->UCL; UCL -> Man; RAL -> UCL; RAL -> Man;
