Abstract :
The next-generation optical network is a service oriented network, which could be delivered by utilizing the generalized multi-protocol label switching (GMPLS) based control plane to realize lots of intelligent features such as rapid provisioning, automated protection and restoration (P&R), efficient resource allocation, and support for different quality of service (QoS) requirements. In this paper, we propose a novel stateful PCE-cloud (SPC) based architecture of GMPLS optical networks for cloud services. The cloud computing technologies (e.g. virtualization and parallel computing) are applied to the construction of SPC for improving the reliability and maximizing resource utilization. The functions of SPC and GMPLS based control plane are expanded according to the features of cloud services for different QoS requirements. The architecture and detailed description of the components of SPC are provided. Different potential cooperation relationships between public stateful PCE cloud (PSPC) and region stateful PCE cloud (RSPC) are investigated. Moreover, we present the policy-enabled and constraint-based routing scheme base on the cooperation of PSPC and RSPC. Simulation results for verifying the performance of routing and control plane reliability are analyzed.
