Abstract
In this paper, a novel distributed dynamic NWLS traffic engineering (dynamic TE) mechanism is proposed and its performance under failure scenarios and increased traffic load is analyzed when compared to other traditional approaches (static IP and TE). The new mechanism periodically updates bandwidth reservation and selects path (resizing and rerouting) for each TE LSP according to its computed traffic load, which leads to path reoptimization and better network utilization. Dynamic TEs performance is analyzed via simulation using real network and traffic scenarios in a newly created simulator, which was carefully developed to reproduce as accurately as possible the behavior of such networks. The simulation results show the significant performance improvement of dynamic TE for several metrics of interest and give insight into other scenarios that could benefit from its deployment.
