A Novel Differentiated-resilience Provisioning Scheme of ServiceLevel Agreements for the GMPLS/ASON Networks

摘要

Network service support to ensure quality of service (QoS) is a key requirement for many applications, wepresent a novel management plane oriented service architecture which provides network resource schedulingservice 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 andpolicy translation structure with excellent expansibility and efficiency in the running process. The architecturecontains four components: Application Monitor Service, SLA Management, Policy management and Servicemanagement. In addition, vertical service mapping and differentiated-resilience provisioning schemes ofservice level agreement(SLA) applied to the GMPLS/ASON networks are discussed, which is expected to bethe near- and long-term network technology thanks, among other things, to the great bandwidth capacityoffered by optical devices.
