PCE-Based Distributed Reservation in Multi-domain Optical Network

摘要：

In this paper, we propose and describe a new distributed reservation protocol for establishing lightpaths in multi-domain optical networks. Distributed reservation scheme is a promising solution for resource reservation and path computation element (PCE) 1, proposed by IETF and considered as a promising scheme to deal with the issue of path computation in support of multi-domain networks, establishes architecture to solve the reservation problem in multi-domain network. Thus, we propose a novel distributed reservation mechanism (PBDR) for PCE-based multi-domain optical network to ease the inefficiency of the step by step reservation process (Source Initiated Reservation and Destination Initiated Reservation). Also, we evaluate the performance of the proposed PBDR through simulation and the result shows the efficiency and availability of the distributed reservation scheme proposed in multi-domain optical network.
