Norway

UNINETT

Existing mesh in UNINETT has approximately 20 servers using www-cache.uninett.no as parent. The main caching proxy servers (top 15 in traffic volume) are marked with red squares on the map of UNINETT network.

Provide cache service to institutions and users in UNINETT.

Europe

DESIRE

Development project.

Objectives

• Survey of Caching Requirements and Alternatives
• Demonstrator for Caching Schemes
• Validation of Caching Schemes
• Cost/Benefit Analysis Report
• Validation of Caching Schemes (extended mesh)

Web proxy caching requirements and recommandations

Survey of caching requirements and specifications for prototype including a survey of the functionality and effectiveness of current caching systems.

Web caching architecture

Design of a Web caching system

Cost/Benefit Analysis

Report on cost/benefit for SURFnet and UNINETT mesh

• European mesh, workshops and documentation
• Deployment in networks
• Mesh autoconfiguration
• Intercache communicaton
• Access reporting and control

TF-CACHE

The objectives of TF-CACHE are to:

1. promote and coordinate the deployment of caching hierarchies in Europe
2. link these with initiatives in the US (NLANR) and coordinate with other work on caching in Europe (DESIRE, INSIGHT, etc.)
3. provide documentation, information and assistance for those wishing to start a caching service

TERENA

• Survey, fall 1996
• COM-MESH
• Cache Registration Service

COM-MESH

COM-MESH has made a mesh of European ISPs, sharing objects from the .com webspace.

The result has been

• reduced latency
• some reduction in trans-Atlantic traffic
• a better understanding of ICP and its limitations

Projects

• Network Monitoring for Cache Servers
• Cache Server "Appliance" Project
• Investigation Into Cache Routing
• Cache local re-director for well-known resources

World

Some interesting projects

• USA
• Australia, New Zealand
• Singapore

NLANR, USA

Squid is software based on Harvest, developped at NLANR.

• Squid
• Exchange Point Service, autoconfiguration and routing issues
• Server management

Australia, New Zealand

Have high costs for access abroad, charging money per byte. The cost model gives a high incentive to reduce traffic, as end users see cost reductions.

Singapore

Access control in proxy is politically important (legislation).
