| The need to establish network connections in a service profile-aware fashion is becoming increasingly important due to the variety of candidate wired and wireless client networks with Quality of Service (QoS) networking infrastructures for some of emerging services like VoIP/Multimedia for wireless networks and Ethernet for wired networks. The control plane optimization of network connections will have to take into account a number of service profile parameters and network constraints to efficiently utilize network resources. In a networking scenario where a multi-service operation in common network infrastructure is assumed, efficient algorithms and protocols for service profile-differentiation and dynamic allocation of network resources will play a key role. To fulfill this need, a new Service Profile-Aware (SPA) control plane model is required to play a vital role in future converged wired and wireless networks in integrating service profile layer, control plane layer, and switching infrastructure layer.; Up until now, the criteria for network infrastructure operation via the existing Internet Engineering Task Force (IETF) and International Telecommunications Union (ITU) control plane models do not consider the service profile layer when establishing network connections. This work proposes the novel concept of a SPA control plane model that demonstrates its superiority over existing control plane models in multiple aspects including full realization of the multi-granularity network resources, and its complete consideration for 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 schemes, 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. Multiple service models were analyzed based on their service profile parameters from both an architectural and mathematical perspective. Detailed mathematical analysis of the three control plane models was performed based on a multi-instance Fixed Point Approximation (FPA) within a multi-granularity Virtual Private Network (VPN) loss networks. The performance analysis of the SPA new traffic management schemes found a significant increase in service allowed load while maintaining lower service blocking probability and network utilization over IETF and ITU control plane models. |
