Grid proxy architecture for network resources

摘要

A Grid Proxy Architecture for Network Resources (GPAN) is proposed to allow Grid applications to access resources shared in communication network domains. GPAN bridges Grid services serving user applications and network services controlling network devices through its proxy functions such as resource data and management proxies. Working with Grid resource index and broker services, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources such as bandwidth for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources. Resource-based XML messaging is employed for the GPAN proxy communication.

主权项

1. A method of supporting operation of a plurality of distributed computing resources interconnected by a communication network, the method comprising:
receiving information indicative of availability of at least some resources of the communication network, the information being in a supply format; translating at least some of the received information from the supply format to a target format usable by at least one of the distributed computing resources; and providing at least some of the translated information in the target format to the at least one of the distributed computing resources to enable analysis of availability of at least some resources of the communication network by the at least one of the distributed communications resources, wherein the supply format is a communications network format not directly readable by the at least one of the distributed computing resources; and the information indicative of availability of at least some resources comprises information indicative of available bandwidth between particular nodes of the communication network.
