چکیده:

Traffic engineering is a mechanism to use network resources more efficiently. Network operators use TE to obtain different objectives such as load balancing, congestion avoidance and average delay reduction. Plane IP routing protocols such as OSPF, a popular intradomain routing protocol, are believed to be insufficient for TE. OSPF is based on the shortest path algorithm in which link weights are set using the inverse proportional bandwidth capacity. Optimization theory helps network researchers to analyze the network behavior more precisely. But this approach lacks feasibility facts. we define a new optimization problem This paper proposes that to address the feasibility requirements a weight set can be calculated in order to be used as a link metric in OSPF
