The network of the future will be based on an integration of optical networking and IP-centric technologies. How this will come to pass, however, will not be as simple or obvious as it might sound. Currently, IP-centric and optical networking technologies do not dovetail. This largely reflects the dissimilar paths over which these two network types have been evolving. IP-centric technologies have been primarily focused on data but are evolving to handle voice, while optical networking has been evolving from the largely voice-centric technologies of Sonet and Dwdm to accommodate data communications requirements.

Additionally, there are a number of different technical and philosophical approaches to achieving the optimal infrastructure to accommodate the characteristics of the IP and optical worlds. For example, the choice of centralized vs. distributed architectures, multi-layer networks vs. pure IP-over-optical, optimal use of routing and switching technology, ATM vs. Mpls in the core, and many others. All promise to expand the ability of the infrastructure to accommodate higher and more granular capacity requirements, operate cost-efficiently, and provide the basis for value-added READ MORE >
