摘要： The present invention provides an Optical Transport Network (OTN) hierarchy that supports full transparency for both Ethernet and Telecom signals. The present invention defines new rates and mapping/multiplexing methods to adapt transparent 10 Gigabit Ethernet (10 GBE) (255/238 and 255/237) and 10 Gigabit Fibre Chanel (10 GFC) (255/237) to Optical Channel Transport Unit-3 (OTU3) at a higher rate. Additionally, the present invention defines new rates and mapping/multiplexing methods to adapt future transparent 100 GBE into an Optical Channel Transport Unit-4-extended (OTU4e) which is an OTU4 at a higher rate to support full transparency.

摘要： The present invention provides systems and methods for supporting native TDM and native Packet switching simultaneously in a meshed switching architecture. Specifically with the present invention, the meshed links are common to both TDM and packet traffic, and both types terminate to a common system interface without the need to separate physical resources and infrastructure; the common termination function has access to both the TDM (Time Slot Interchange (TSI)) switching and packet switching elements. Native TDM switching and packet switching operate in concurrently in the mesh over common links, with the personality of the links derived by the card type (attached to the mesh). In this, a given card or slot in a system can communicate in the native format to both packet based cards (slots) or TDM based cards (slots) simultaneously with no preconceived restrictions or limitations on slot or link definition.

The method includes: mapping packet service data or constant bit rate data to a Super Optical Channel Data Unit (ODUS) and mapping the ODUS to a Super Optical Channel Transport Unit (OTUS); distributing the OTUS to a plurality of electrical lane signals, dividing the plurality of electrical lane signals into one or more groups and mapping the one or more groups of electrical lane signals to corresponding Super Optical Channels (OChSi), wherein rates of the ODUS and the OTUS are both N times of 100 Gb/s, a rate of the OChSi is M times of 100 Gb/s, tributary slot sizes of the ODUS and the OTUS are both 100 Gb/s, where N is a positive integer equal to or greater than 2, i is a positive integer, and M is a positive integer equal to or greater than 1 but less than N. The present document enables an operator to deploy a beyond-100 G optical transmission system more flexibly, without being limited to select a fixed rate, and improves the spectrum utilization rate of fiber as well as the flexibility and the compatibility of a system.
