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.

validate a set of service definition and traffic engineering tools
to obtain quantitative end-to-end QoS guarantees through
careful planning, dimensioning and dynamic control of
scalable and simple qualitative traffic management techniques
within the Internet (i.e. diffserv)”
• TERENA minor role: Web site, workshops in 2001
and 2002

–
–
–

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, usercontrolled 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

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
LDAP BoF
• LDAP BoF in Amsterdam on 12 May 2000 discussed:
– Progress of DIRECT project
– Integration of X.509 PKIs and LDAP:
• Presentation by DFN’s directory centre
• Different NRENs have different strategies for supplying their
customers with PKI solutions.
• Next meeting may look into specific proposals for CA policies
across NRENs and for naming 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
Force on LDAP Deployment was appropriate. Draft Terms of
Reference will be drawn up. Meetings to be adjacent to NameFlow
meetings. Next meeting towards the end of September 2000
