Emerging Trends in Packet Optical Convergence
Abstract
Packet-optical transport has been a major trend in optical networking over the past 18 months. New products have emerged that combine WDM transport, ROADMs, Sonet/SDH ADMs, and centralized carrier Ethernet switching in a single converged device. These products are known packet-optical transport systems (P-OTS).
To date, the P-OTS evolution has been all about the metro, but we're now seeing P-OTS move into the core of the network. Part of the reason core P-OTS is emerging now is that the core transport network has largely been ignored for a couple of years while the industry has focused on rebuilding access, metro, and aggregation networks for packets and IP. In reality, growth in Ethernet ...
