Research on Networks Report on session on Grids & access Klaas Wierenga SURFnet Middleware Services Utrecht, 29 April 2004

Structure of the session General intro SURFnet, UvA, TI, Nortel Zooming in on the research topics Discussion & identifying topics of common interest –Short term: this year –Rest of project –Demonstrators Allocation of responsibilities

The vision A backbone is nice, but the users and resources are at the edge E2e characteristics are essential Identity networking is key, supported by AAA, trust infra (federations) and provisioning & management tools Target community: both grids users, campus users, and roaming users – anywhere, anytime, any device

4 research topics in GigaPort-NG Roaming and personalized service provisioning –provisioning, universal SSO, AAA, federations AAA for grids in multiple administrative domains –Architectures, AAA models, brokerage, … Grid security –Data integrity, authenticity, confidentiality Service Management Frameworks –How can SMFs support the above

Identified research topics Reference architecture for network and application provisioning (based upon RFC2903/2904) Mapping of EduRoam, A-Select, UvA AAA and CO2 on this architecture AAA for network access AAA for network provisioning (across multiple domains) Application driven network characteristics

Short term objectives Define reference architecture Mapping currently available modules onto this architecture Integration of A-Select with UvA AAA and CO2 Identifying relevant external liaisons (e.g. GGF, IRTF/IETF, OASIS,…) Identify candidates for vertical demonstrators (e.g. healthcare, media/entertainment)

What we are going to do

Short term demonstrator (2004) User (via A- Select) Source Destination Bandwidth Start-time Stop-time

Mid term goals Application driven authorization Role-based authorization Web-services interface between AAA and A- Select AAA federation Role-based routing (aka Dijkstra-NG)

Role-based routing
