The Optical Burst Switching (OBS) paradigm is regaining greater attention by the professionals and researchers of the optical networking field, as it offers a number of advantages when compared with other optical switching paradigms. This type of technology was developed with the objective to carry information all-optically without using any kind of buffering device. However, due to its one-way signaling process, the presence of a control plane is extremely useful to manage complementary signaling and routing features, providing flexibility, reliability and taking more benefits of the OBS networks. The goal of this project is to extend Generalized Multiprotocol Label Switching (GMPLS) control plane architecture to properly handle OBS networks. In spite of GMPLS is not prepared to lead with these type of networks, this flexible architecture has been seen as a potential candidate to be used as the control plane of other kinds of optical networks (e.g., IP, Ethernet, Optical Circuit networks) and therefore to manage control OBS networks. In this project, the existent event-driven JAVA simulator for OBS networks – JAVOBS – is extended to simulate a possible interoperability model between GMPLS and OBS technologies. The first objective is to implement a new control layer (GMPLS) separated from the data layer of the OBS network. The second and main objective fits on the basic signaling procedures implementation of the GMPLS Reservation Protocol-Traffic Engineering (RSVP-TE) protocol, in order to analyze the performance of the OBS network’s behavior when it is controlled by such interoperable control plane (GMPLS/OBS).
