The problem of computing weights on the links and routing data in shortest paths known as OSPF weights setting problem (OSPFWSP) is NP complete. OSPFWSP is defined as given a set of traffic demands between origin-destination pairs, the OSPF weight setting problem consists in determining weights to be assigned to the links so as to make efficient use of network resources. In this book, a problem of OSPF traffic routing in hybrid network is stated. Three different methods are proposed for solution and implemented in real environment. Also three proposed algorithms are introduced for solving...
