Abstract

The deployment of PCE (Path Computation Element) architecture in high-speed MPLS/GMPLS networks is widely accepted and facilitates path setup operations for applications with explicitly defined objective functions. In this paper, we propose a new link-abstraction mechanism, which improves the method of establishing domain topology of parent PCE, and further aggregates the abstract topology in the hierarchical PCE method, thus simplifying the topology aggregation of the multi-domain. Meanwhile, considering the constraints of multiple factors which affect cross-domain path calculations, we provide a relatively simple way to select, which solves the key problem of determining the “domain sequence” in the process of cross-domain path calculation. Simulation results show that the proposed method has better performance in terms of blocking probability, end-to-end delay and resource utilization rate.
