Abstract:
In a multi-protocol label switching (MPLS) network based on optical code division multiplexing (OCDM), each core switching node is assign with one code sequence with N chips for each specific input/output pair. With optical code division multiplexing, it creates a new way to utilize optical codes as optical labels. In this method, logic operations corresponded a look-up table is avoided, which is the toughest challenge for optical processing. Instead, it only needs to check the label in the core node with the function of optical correlation. As the users and Internet traffic continue to grow rapidly, it is expected that optical networks will support a larger number of users in the future. However, there is a scalability problem that the more the number of core nodes exists, the more code sequences are needed. To solve this critical problem, we consider a situation that can reuse label in order to save the number of utilized labels. Under this structure, there is a significant increase in the number of users that can be supported compared to the original ones. In this thesis, we compare the relationship of the number of utilized labels and supported LSPs (label switching paths) in both situations with and without reusing labels. We also discuss the issue of cost efficiency and bandwidth efficiency. Further, the discussion of BER performance is also included.
