Traffic Engineering System Based on Adaptive Multipath Routing

Traffic engineering is a method of optimizing the performance of a telecommunication network by dynamically analysing, predicting and regulating the link utilization over the network. It handles the unexpected traffic dynamics for achieving better quality of service and overall network performance in wireless sensor networks. One of the existing AMPLE (Adaptive Multi-topology traffic Engineering) is an efficient traffic engineering and management system that performs effective routing by using multiple virtualized routing topologies using the components: offline link weight optimization that takes the physical network topology as an input and tries to produce maximum routing path diversity across multiple virtual routing topologies for long term operation through the optimized setting of link weights. Based on these diverse paths, adaptive traffic control performs intelligent traffic splitting across individual routing topologies in reaction to the monitored network dynamics at real time. The proposed multipath routing system offers a promising solution for traffic dynamics in today’s networks in an efficient manner by considering the effective link utilization factors in addition to this and concentrated in providing proper analysis in case of node failure in the networks.
