Paper Abstract

The major goal of TE (traffic engineering) is to facilitate efficient and reliable network operations while simultaneously optimizing network utilization and traffic performance. Therefore it is necessary to introduce TE mechanism to ISPs’ (Internet Service Providers’) networks with the purpose of improving network performance and reducing costs. In this paper, a novel TE mechanism based on GMPLS (Generalized Multi-Protocol Label Switching) is proposed and analyzed in detail, and is demonstrated on a network with IP over ASON (automatically switched optical network) architecture. The ASON layer acts as the server of IP layer which uses traditional IP protocols, and realizes TE mechanism through the method of dynamically changing bandwidth seen by IP layer through UNI (User-Network Interface). Simulation results have shown that the model has a superior operational agility to the conventional method and lower congestion probability in certain conditions.
