Performance analysis in adaptive traffic engineering of multiprotocol label switching networks

Multiprotocol Label Switching is an emerging technology, which plays a key role in Internet Protocol networks by providing Adaptive Traffic Engineering features. Multiprotocol Label Switching Adaptive Traffic Engineering avoids network congestion by balancing the loads among the Label Switching Paths and ensures that intermediate routers are not required to perform Traffic Engineering activities besides forwarding packets. The current Internet infrastructure lacks key characteristics in terms of delay, jitter, and loss, which are required for multimedia applications. Implementing the Multiprotocol Label Switching Adaptive Traffic Engineering can fulfill these requirements.; It is envisioned that Traffic Engineering is performed only for the traffic that does not require resource reservation, but may need provisioning on an aggregated basis. We propose that Multiprotocol Label Switching Adaptive Traffic Engineering can be done by establishing multiple Label Switching Paths, comparing the Offered and Required Load, creating new and releasing the old Label Switching Paths between the given Ingress and Egress Switch Routers in the Multiprotocol Label Switching domain Moreover, we do not impose any particular scheduling, buffer management, architecture, and traffic characterization, on the Label Switching Routers.; In this dissertation, we propose an algorithm for the Multiprotocol Label Switching Adaptive Traffic Engineering development We also, propose three different Multiprotocol Label Switching Adaptive Traffic Engineering system models. These models explain how Multiprotocol Label Switching Adaptive Traffic Engineering dramatically improves the performance of service providers and carrier backbone networks. These models calculate the performance measures for the multiple Label Switching Paths between Ingress and Egress Switching Routers. To ensure the optimum provisioning of traffic in the network, the router, which distributes the packets among the existing Label Switching Path, allowing for maximum utilization of the required number of these paths is associated with performance metrics. Load balancing can be performed among these paths by creating and releasing them and thereby adjusting the Offered and Required Load. The performance metrics of the network are thoroughly studied, formulated and calculated. The performance metric consists of the values of Probability of no Packet in the queue, Blocking Probability, Congestion Measure Factor, Delay Variance, Mean Packet Delay, and the Efficiency of the Network.
