Abstract:
1. A method for multiplexing and mapping optical signals, comprising: acquiring a label object that indicates a multiplexing and mapping relation, wherein the label object comprises a label and a label header, and the label comprises a type indication field and a tributary slot (TS) indication field, wherein the type indication field occupies a first portion of bits in the label, the TS indication field occupies a second portion of bits in the label, and the second portion of bits are part of or all of the bits except the first portion of bits in the label; wherein the label object is used to predefine a multiplexing and mapping policy between a first optical signal on a first optical channel and a second optical signal on a second optical channel, wherein the multiplexing and mapping policy comprises a matching relation between a type of the first optical signal and a type of the second optical signal, and a TS of the second optical signal occupied by each part of the first optical signal when the first optical signal is multiplexed and mapped to the second optical signal according to the matching relation, wherein the matching relation is indicated by the type indication field, and the TS is indicated by the TS indication field; and multiplexing and mapping the first optical signal to the second optical signal according to the multiplexing and mapping policy.
