Project Summary
The Managed Bandwidth - Next Generation (MB-NG) will create a
pan-UK Networking and Grid testbed that will focus upon advanced
networking issues and interoperability of administrative domains.
The project will address the issues which arise in the sector
of high performance inter-Grid networking, including sustained
and reliable high performance data replication and end-to-end
advanced network services. The project will also directly address
the issues which arise in the sector of interoperability between
the Adminstrative Domains with regards to Quality of Service and
High Throughput.
We are collaborating with:
Objectives
The primary objective of MB-NG is :
| |
To demonstrate e2e managed bandwidth services
in a multi-domain environment, in the context of Grid project
requirements. Also implicitly to determine how well QoS
works and to develop suitable policies and potentially separate
service level specifications for specific applications
&
To investigate and develop high performance data transport
mechanisms for Grid data transfer across heterogeneous networks. |
Both the e2e and multi-domain are crucial – whatever managed
bandwidth model is used, it has to be shown to work between components
of Grid application software, and address the issues which would
arise if different administrative domains would attempt to configure
inter-domain services according to SLSs. Managed bandwidth in
this context is the provision of protected bandwidth channels
between defined endpoints.
In more detail the principal objectives are:
| • |
to demonstrate configuration of managed
bandwidth (MB) services separately within each of several
independent domains |
| • |
to demonstrate interoperation of MB between
multiple administrative domains simulating a Core network
and local site networks, addressing SLA/SLS and policy issues; |
| • |
to consider the policy issues associated with
the provision of MB and in particular define a Service Level
Specification for MB within each domain and a end to end SLA
within the JANET context. It is envisaged that SLS’s
and an SLA will be defined at the start of the experimentation
and will be revised as appropriate following practical experience. |
| • |
to demonstrate use of Managed Bandwidth
services by Grid applications, i.e. using real Grid high
and low priority traffic classes |
| • |
to interface MB services to Grid middleware
APIs in some way to be specified (i.e. some notification
from API to at least ingress). |
| • |
to provide a vehicle for UKERNA to gain experience
of the use of MPLS for traffic engineering in the Core |
| • |
to allow UKERNA to implement a mechanism to
effectively replace the previous ATM managed bandwidth service |
| • |
where possible to demonstrate end-to-end
network services to CERN as part of our EU-DataGrid commitments |
| • |
where possible to demonstrate end-to-end
network services to the USA in collaboration with US Grid
groups |
