A novel differentiated-resilience provisioning scheme of service level agreements for the GMPLS/ASON network

Network service support to ensure qua lity of service (QoS) is a key requirement for many applications, we present a novel management plane oriented service architecture which provides network resource scheduling service in large-scale GMPLS/ASON network environment based on the service level agreement(SLA) conducted between service customers and service providers. It applies the updated service-oriented and policy translation structure with excellent expansibility and efficiency in the running process. The architecture contains four components: App lication Monitor Service, SLA Management, Policy management and Service management. In addition, vertical service mapping and differentiated-resilience provisioning schemes of service level agreement(SLA) applied to the GMPLS/ASO N networks are discussed, which is expected to be the near- and long-term network technology thanks, among other things, to the great bandwidth capacity offered by optical devices.
