8 February 2005 Prospects and challenges of photonic IP networks
Author Affiliations +
In designing future networks and systems, we must consider the current paradigm changes; IP convergence and the divergence of architectures and technologies. To start with, I will discuss broadband access technologies being deployed in different countries. Harnessing the full power of light will spur the creation of new broadband and ubiquitous services networks. The key requirements of enhancing the performance and reducing the cost of future IP-based multimedia communication networks can be effectively achieved by exploiting wavelength routing. This requires, however, not only the optimization of photonic technologies but also coordination with complementary electrical technologies. MPLS will play the key role, and its status and the present perception of its inefficiency are discussed. The evolution of GMPLS and the way to be taken for further development are depicted. Finally, I discuss some of the cutting-edge photonic transport technologies that will enable us to achieve another advance in network performance in the future.
