A Service Profile-Aware Control Plane with a Comparison to IETF ITU Approaches

摘要

Existing Internet Engineering Task Force (IETF) and International Telecommunications Union (ITU) optical control plane models do not consider the service profile layer when establishing network connections, this work proposes the novel concept of a Service Profile-Aware (SPA) control plane model that is superior to existing models. SPA includes a full realization of the multi-granularity network resources, and considers services' architectures and their associated service profile feature set. Detailed comparison between the three control plane models were considered from multiple dimensions including traffic management scheme, components level interaction between (service profile, control plane, network infrastructure) layers, and network infrastructure realization from both horizontal "network domains" and vertical "resource granularity and network partitions" perspective. The service models were analyzed based on their service profile parameters from both an architectural and performance perspective. Mathematical analysis of the three control plane models was performed using multi-instance Fixed Point Approximation (FPA). The performance analysis of the new SPA traffic management schemes found a significant increase in service allowed load while maintaining lower service blocking probability and network utilization as compared to the IETF and ITU control plane models.
