Quality of Service (QoS) routing aims to find path between source and destination, satisfying the QoS requirements; to efficiently use the network resources and underlying routing algorithm; and to find low-cost paths that satisfy given QoS constraints. One of the key issues in providing end-to-end QoS guarantees in packet networks is determining feasible path that satisfies a number of QoS constraints. The authors present an Optimized Multi-Constrained Routing (OMCR) algorithm for the computation of constrained paths for QoS routing in computer networks. OMCR applies distance vector to construct a shortest path for each destination with reference to a given optimization metric, from which a set of feasible paths are derived at each node.
