Three Trends in Networking 1. TDM is past its prime § § Built primarily Three Trends in Networking 1. TDM is past its prime § § Built primarily for voice, and adapted reasonably successfully for leased lines, fine-grained TDM (PDH/SDH) is increasingly irrelevant for Next Generation Networks TDM is also very expensive on a cost/Gbps basis 2. Packet transport is on the rise § § There is recognition that transport must focus on packets, not bits There are multiple approaches, and a lot of confusion out there 3. Interest in the Packets+Photons Phenomenon is growing § § There is also recognition that the worlds of packets and of optical transport must come together Again, there are several approaches, and no clear way forward What Should Be Done?
