Abstract

With the advent of new services based on IP, the need for bandwidth grows rapidly at the Internet backbones. The need of carry even more traffic and keep costs as lower as possible, points to new solutions with requirements of escalability, flexibility, low cost and easy of operation. Today, to carry this traffic in an efficient way and with low cost has been a great challenge, specially with the current infrastructure based in four layers. Some proposals have appeared to address these issues. Among them the GMPLS is distinguished. The GMPLS and its extensions to the routing and signaling comes to setting itself as an excellent solution to address the current problems found in the management and provisioning of the great ISPs.
