MB-NG (Managed Bandwidth Next
Generation)
† Objectives:
„ To demonstrate managed bandwidth and QoS
services in a Grid environment (over MPLS);
„ To demonstrate sustained gigabit/s scale data
transport across the wide area network (over
MPLS);
„ To engage in tests with collaborative partners in
the EU and USA.
† Partners: UCL, Man, CLRC, UKERNA, Cisco

Objectives:

†
Development of an open and extensible architecture for
network monitoring based on modularity. Performance
requirements are for monitoring 10 Gbps links.
Development of novel high-performance measurement tools.
Which will allow any desired analysis to be performed upon the
results
Extrapolation and analysis of architectural requirements,
constraints, and trade-offs which will be necessary to monitor
networks of 40 Gbps and beyond, and develop a strategy to
achieve this goal.

GridMcast
† Objectives:
„ Investigation of the implementation issues of
multicast transfers within the Grid framework.
„ Provide a far superior method of software
distribution, data replication and mirroring, and
access to shared data for visualisation and analysis.
„ All of these tasks are key to the success of PPARC's
major Grid- based projects, GridPP and Astrogrid,
which foresee Grids of international scale, with
thousands of nodes.
† Partners:
„ Cambridge e-Science Centre, GridPP(EU), ATLAS
(CERN)
FutureGRID
† Objectives:
„ Deploy Xenoservers Active nodes at Access Grid sites
(all e-Science Centres)
„ Port the Pastry message routing and the Scribe event
notification frameworks to Xenoserver with
accounting and resource management of network
usage (multicast congestion control)
„ Design suitable API based on GRID GGF models
WSDL/OGSA
„ Refinement and implementation of application set
(vic, rat, fcast, powerpoint) to new infrastructure,
including gateways to legacy “native” multicast
versions.
† Partners:
„
Cambridge (CLab, Microsoft Research).
GRID Resource Scheduling (GRS)
† Objectives
„ QoS and network features integration in the
GRID resource model.
„ Dynamic Requests of Bandwidth for capacity
from end-users.
„ Micro-management of QoS at edge sites.
„ Highly decentralised, multi-domain QoS
management under local administrative controls
