Extended Application Of SIP In Optical Grid

Optical Grid will be an attractive proposition, as the bandwidth of electrical network becomes the bottleneck of grid application. To support Grid application much better, there are two main common challenges to typical optical network, one is bandwidth provisioned and scheduled on-demand, the other is user or application management and control of the network resources. Under this background, investigations of architectures, protocols and algorithms of optical networks for grid applications are attracting attentions all over the world.As a well known session control protocol, Session Initiation Protocol (SIP) could provide all the messages that are necessary to control a long lasting communication session, and it supports any "user defined" functionalities, which has wide application in many fields and important research value. This paper will focus on investigation of SIP-based service plane provisioning and implementation in OBS network.In this paper, key issues of application of SIP in optical Grid are studied first, including several typical kinds of architecture for optical grid and problems, investigation of application model, principle and implementation of typical P2P-SIP network, and P2P-SIP based Grid Resource management mechanism. Then, a novel architecture of optical grid is proposed, by introducing a SIP-based service plane to OBS control plane, which is responsible for supply session-control service for Grid users, and resources management for Grid applications. At last, an experiment has been implemented on an exiting LOBS test-bed, and the result proves the feasibility and effectiveness of the new architecture with P2P SIP-based service plane.
