A Multi-path Routing Protocol For Unidirectional Networks
نویسندگان
چکیده
Most of routing protocols designed for the Internet today are for networks with bidirectional links. These protocols cannot be easily extended to networks with unidirectional links without increasing cost. In [1], Chen et al. presented a distance-vector-based routing protocol for unidirectional networks where a routing table is derived for each node in the network. In this paper, we extend the protocol in [1] by keeping one path for each outgoing link of a node to maintain multiple paths in the corresponding routing table. The path for a specific outgoing link is the shortest path from the node to the destination through that outgoing link. Thus, the protocol provides alternative paths that are vital in the dynamic network environment.

متن کاملLink-state routing in networks with unidirectional links
It is shown that a unidirectional link of a network can be used for routing only if it has an inclusive cycle, which is a path that can carry routing updates from the downstream node to the upstream node joined by the unidirectional link. A new routing algorithm for networks with unidirectional links is then presented, which incrementally disseminates linkstate information and selectively utili...
