Networking for e-Science
Most e-Science work so far assumes
that the network resources and
functions (high capacity, QoS,
monitoring, control, accounting,
security, etc.) are - or will be available to the applications as and
when requested.

A summary of areas of interest
l
l
l
l
l
High Capacity
Predictability / Timely delivery
Security
Reliability
Users - the usual suspects:
l
l
HEP, astro-physics, bio-informatics, medical
informatics, materials science, etc.
others (non e-Science) may also have demanding
needs

Future research areas
l
Security:
l
l
l
Monitoring and measurement:
Access to network information and services
l
l
l
e.g. QoS + ECN + QoS control + IPv6
Inter-domain issues:
l
l
APIs, middleware, underware
Unified mechanisms across network:
l
l
especially DDoS + intrusion detection
connectivity policy, routing/path control
Optical (and hybrid optical) routing
Accounting (and charging?)
17
Future standards/collaboration
l
Growing Grid and e-Science interest:
l
l
l
l
research, development, deployment, testing,
evolution
Growing engagement with industry
Continued participation in GGF + IETF/IRTF
Continued collaboration at National,
European and International level:
l
e.g. GLIF (Global Lambda Infrastructure Forum)
