Study of IP Network interior gateway routing for optimization

This paper reviews recent work on routing optimization for interior gateway protocols, and identifies important areas where further research is needed. Recently, a new approach to the routing optimization has been identified, which has proven to be of significant relevance to companies that have adopted it. This approach is based on the optimization of link weights with different function that may affect shortest path selection, traffic distribution and finally network routing cost into a single optimization model. The problem of simultaneously considering the characteristics and requirements of different functions to perform an overall optimization has attracted the attention of researchers in recent years and some models have been proposed in this direction.
