Method, apparatus and system for processing flexible-rate signal

摘要

The present invention relates to a method, an apparatus, and a system for processing a flexible-rate signal. A signal from a client side is encapsulated to n optical channel data unit ODU signals. The n ODU signals are encapsulated to a flexible optical channel transport unit OTU signal. A nominal bit rate of the flexible OTU signal varies according to a value of n and the n is an integer greater than or equal to 1.

1. A method for processing a flexible-rate signal, comprising:
encapsulating the flexible-rate signal from a client side to n optical channel data unit (ODU) signals, wherein the n ODU signals are of a same type and n is an integer greater than 1, wherein a value of n is selected so that a sum of n ODU nominal bit rates is greater than an allowed traffic volume of the signal from the client side and a sum of n−1 ODU nominal bit rates is less than the allowed traffic volume of the signal from the client side; and encapsulating the n ODU signals to a flexible optical channel transport unit (OTU) signal, wherein a nominal bit rate of the flexible OTU signal varies according to the value of n.
