The future trend is to integrate a constantly increasing number of services in the GMPLS/ASON networks.
Some services have very high resilience requirements, while other services have lower ones. This scenario
calls for frameworks capable of provisioning for multiple services in a cost efficient manner. This article
proposes a differentiated-resilience provisioning scheme applied to the GMPLS/ASON networks, 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. Finally, a critical evaluation of the state-of-the-art and future
challenges facing operators and designers is given. Our numerical results show that the differentiated
resilience scenario has better performance than that of dedicated and shared protection and received
connections in the differentiated-resilience are 31% higher than that of shared protection and are 60% higher
than that of dedicated protection.
Network service support to ensure quality 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: Application 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/ASON 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.
