A Novel Signaling Method to Decrease the Connection Setup Time in Optical Grid Networks

摘要

Geographically-distributed computing application for science and enterprise are emerging services for providers, and the optical network is expected to be involved in such the grid computing application by using GMPLS protocols for its high performance. In the optical grid network, network delay and fault recovery time are very important for some special distributed application. However, bandwidth guarantee and dynamic bandwidth provisioning are achieved by the cost of LSP setup delay, In this paper, a parallel GMPLS-based signaling method is proposed to decrease the connection setup time effectively so as to provide fast dynamic bandwidth for grid applications. We implement this novel method on our optical grid network test-bed (GOGrid) and draw the conclusions.
