Intra‐domain traffic engineering with shortest path routing protocols

Throughout the last decade, extensive deployment of popular intra‐domain routing protocols such as open shortest path first (OSPF) and intermediate system–intermediate system (IS‐IS), has drawn an ever increasing attention to internet traffic engineering. This paper reviews optimization techniques that have been deployed for managing intra‐domain routing in networks operated with shortest path routing protocols, and the state‐of‐the‐art research that has been carried out in this direction.
