Next generation Synchronous Optical Networking equipment is paired with data centric interfaces and packet switching engines to provide reliable Metropolitan networking for Headend interconnects. This integration has lead to new developments in multiplexing structures and bandwidth allocations. By creating more granular packet containers, and dynamic allocation, services are more efficiently packaged onto the transport network. Implementing priority based queuing allows for services to be expedited onto the network. Services bound by Quality of Service constraints in delay and delay variance can be individually managed across the transport network. Differentiated Services, Open Access and Carrier Class transmission will merge into one consolidated backbone serving entire metropolitan regions.
