Flow-Aware Multi-Topology Adaptive Routing

摘要

Internet routing processes currently rely on protocols that were developed more than ten years ago. Today, we have far more computational power and memory at our disposal, and it is possible to take advantage of these resources in order to greatly increase the efficiency of routing protocols. Therefore, we propose a new approach to routing packets in IP-based networks: Flow-Aware Multi-Topology Adaptive Routing, or FAMTAR. FAMTAR combines flow-aware traffic management and an adaptive routing mechanism. A standard routing protocol is used to find the optimal path between two nodes in a network. FAMTAR makes it possible to automatically create additional paths when such demand occurs. Between two endpoints, the transmission may follow $n$ different paths, where $n$ is limited only by the topology of the network. In this letter, we compare FAMTAR to a classic routing protocol and demonstrate FAMTAR's superiority.
