Overview of University of Amsterdam

progress•University of Amsterdam and SARA created joint research lab (Amsterdam Lighthouse)

•Demonstrated AAA software in combination with Nortel control plane at SC2004

•Making it easier for others to obtain AAA software, by creating demo ASM, writing documentation

AAA software• JCA is not used for communications anymore, only plain

webservices. This makes it simpler, and thus more stable (there were some bugs in our JCA code, requiring period restarts)

• Plain XML-RPC is used for webservices, no special flavour like WSRF.

• Create a demonstration (magic eight-ball), and created an ASM to connect to RADIUS.

• Currently we are rewriting documentation the above (demo + how to install + how to write ASM - This will be published online, hopefully with a week or two (begin of february). Currently, only software and out-of-date docs were available by email. Contacts: Fred Wan, Bas van Oudenaarde, http://www.science.uva.nl/research/air/projects/aaa/

Future Plans• Virtualizing our resources with webservices,

allowing a user to set up and tear down a path within our domain. contact: Paola Grosso

• Integrate AAA with UCLP. contact: Bas van Oudenaarde

• Interdomain Path Discovery algorithms. contact: Freek Dijkstra

• Use the Grid as a network testing tool (within GigaPort NG project). contact: Paola Grosso

• Experiment with token-based networking, using Intel processor. contact: Leon Gommans

• Create firewall research group in GGF. contact: Leon Gommans

Questions•What type of networks do we require?

Host to host or LAN to LAN?

•How to cope with faults in the network setup? What if the network is automatically set up, but ‘does not work’ end-to-end?

•How to combine different type resources, if the resources do use non-synchronized schedulers?
