The Perspective of Multipath Routing
Multipath routing refers to the use of multiple paths rather than a single path to forward traffic through the network from source node to destination node. Multipath routing improves overall network performance by making the best use of available network resources. If multiple paths are used for traffic transmission, traffic will be redirected to the backup path if the active path fails or there is congestion. Furthermore, by distributing traffic, multiple paths can be used concurrently. Consequently, Multipath routing can be more efficient than single path routing in terms of network utilization and load balancing. It can significantly reduce congestion and increase network throughput, thereby increasing network reliability. The calculation of multiple paths and traffic distribution among multiple paths are the two main concerns when implementing a multipath routing scheme. Various algorithms for effectively calculating the multiple paths are presented in the literature. In this chapter, we discussed some multipath routing approaches that take path construction and path selection into account when distributing the flow.
