IPv6 and the Grid
IPv6 testbed exists in UK (6Net)
connects: Southampton – UCL - Lancaster
SuperJANET-4 is being IPv6 enabled
The GGF has an IPv6 working Group :
UCL is involved in this (one Chair)
Southampton &UCL porting Globus-3 to IPv6

Summary
Activities in the UK are ensuring that the network is ready to serve the
Grid at all levels
Infrastructure
Current 10 Gbit/s network - Future “multi layer” hybrid network
UKLIGHT optical networking node
Protocols
IPv6 community and network infrastructure
Advanced TCP and non-TCP transport protocol work
QoS
Services & Middleware
Performance measurement and publication to Grid Information services
Diagnostics for Grid operations
Resource allocation and reservation Middleware
EGEE Responsibility
Many opportunities for UK –Japan Joint Network Activities using
research network infrastructure

GridPP Testbed
All HEP experiment
sites are part of
Gavin’s “green dot”
map.
At least a Globus
gatekeeper was
running at some point.
In almost all cases
this is actually an EDG
gatekeeper - ie with
extra functionality.
