PlanetLab is a global overlay network for developing and accessing broad-coverage network services. Our goal is to grow to 1000 geographically distributed nodes, connected by a diverse collection of links. PlanetLab allows multiple services to run concurrently and continuously, each in its own

Thousands of licenses were offered, varying in both geographic coverage and the amount of spectrum covered. The bidders were the local, long

We advocate a stronger effort by developing Asian countries to prioritize services negotiations in their regional arrangements, and to expand coverage of services in those pacts to a broad range of infrastructure

OSTI, the source selected for our proof-of-concept prototype, is a major government energy database offering broad coverage of alternative energy resource information including solar, wind, hydroelectric and geothermal topics, among others.

Key Infrastructure that provides for authentication, non-repudiation, anti-playback, and access control. This framework supports a broad spectrum of approaches, ranging from hierarchical to peer-to-peer. The system topology and rules governing access to intrusion detection services is based solely

broad-coverage precision grammars. The Grammar Matrix customization system is a web-based service which elicits typological descriptions of languages and outputs customized grammar fragments suitable for sustained development into broad-coverage grammars. The created grammars use the formalism of Head

We also review a range of services provided by noncarrier organizations specialising in maritime data. Reviewed services from non-carrier organizations are considered as belonging to either one of two broad
