Computing the multi-constrained quality of service (QoS) routing according to multi-dimensions vector will cause that actual transmission route is inconsistent with optimal theoretical route and that QoS cannot meet requirements. To solve this, a novel multi-constrained QoS routing algorithm based on vector converting is proposed. The multi-dimensions(More)
A layered algorithm of bidirectional search is proposed for the problem of the route with multiple restrictions. The first step is to calculate the reachability set of path to each intermediate nodes using starting from the source nodes and the target nodes separately; and the second is to filtrate the path in the set. The reachability of paths can be(More)
To indicate exactly the reliability of large-scale high-speed broadband communication network with domain partition and interconnection, a novel reliability index weighed by normalized capacity is defined, which organically combines connection performance with capacity. The correctness and rationality of the index are demonstrated on the aspects of(More)
