Original Abstract

This paper discusses internetworking and how routes are discovered and used with one of the most commonly used routing protocol Open Shortest Path First (OSPF). The limitation of this protocol is that the algorithm does not take actual link load into consideration. OSPF is not traffic aware. This paper suggests using an alternate costing strategy to avoid this problem. The alternate strategy considers link load as an additional parameter for a final metric calculation. An integer value is assigned for the load of a link as the additive component of metric. Metric significantly affects the selection of links in the shortest path first. Since the link load is a dynamic variable, Exponential Weighted Moving Average is used for the proposed method of metric additive calculation.
