Objectives of the TERENA Technical Programme

• to co-ordinate network development activities on behalf of the TERENA members;

• to pilot new networking services on behalf of the TERENA members;

• to assist the transfer of technology between TERENA members;

• to participate in global network development activities, whilst avoiding unnecessary duplication of effort with other organisations.

Caching and network storage

• TF-CACHE

– Project “FTP Mirror Tracker”

– Project “Extended Cache Statistics”

Project “FTP Mirror Tracker”

• Alexei Novikov ITEP Russia & Martin Hamilton, University of Loughborough, UK

• The “FTP Mirror Tracker” enables transparent, user-controlled redirection to the nearest FTP mirror sites that are exact replicas of the original source

• Software available from the project Web site

• TERENA Project Report published in April 2000 and distributed at TNC2000 and WCW5

http://squid.itep.ru

Project “Extended Cache Statistics”

• Jens Voeckler, University of Hannover, Germany

• “Seafood” is software suite for analysis of data extracted from Web cache log files. A Web-based interface is used to access typical selections as part of Seafood. Long-term and easy-to-access storage allows for trend analysis, correlations etc.

• TERENA Project Report published in April 2000 and distributed at TNC2000 and WCW5

TF-CACHE

• TF-CACHE was established in 1996

• TERENA has excellent reputation and track record because of its caching activities

• Web caching well-developed and increasingly commercial activity

• Now need to redefine to scope of the work under TF-CACHE

• TF-CACHE Open Meeting & BoF, Lisbon 21 May 2000

The TERENA Portal Concept

• Idea launched October 1999

• Combines expertise of TERENA’s community in indexing/searching, caching/storage, streaming

• Project plan February 2000

• Currently being discussed with potential partners

Security and directories: Middleware

• TF-CSIRT

– Project “Directory Replication Co-ordination” (DIRECT)

– LDAP BoF

– Middleware Workshop

DIRECT project

• Minor TERENA project conceived in collaboration with DANTE

• To help migration to LDAP

• Carried out by SURFnet staff, DANTE staff, TERENA staff

• December 1999 - June 2000

www.terena.nl/projects/direct

and storage of certificate entries– Global Directory Index System:

• Three presentations• Agreed that pilot system using the DESIRE distributed indexing system and the GIDS server

of Catalogix should be set up. DANTE will provide storage facility for the index objects for the purpose of the pilot

LDAP BoF (cont.)

• Discussion in LDAP BoF (cont.):– Meeting felt that a TERENA activity in the form of a TERENA Task
