Abstract

The embodiment of the invention discloses a client signal transporting method in an optical transport network, and transport equipment; the method comprises the following steps: dividing the payload of an optical payload unit signal into m first particle time slots, and dividing the first particle time slot of the m first particle time slots into n second particle time slots, wherein the first particle time slot rate equals n times of the second particle time slot rate, m is a positive integer, and n is a positive integer bigger than 1; mapping the first client signal to the payload to which one or more second particle time slots of the n second particle time slots are located; adding the first particle time slot cost and the second particle time slot cost for the optical payment unit signal so as to form an optical data unit signal; sending the optical data unit signal. The method and equipment can improve the bandwidth transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method and transmission equipment for transmitting client signals in an optical transmission network. Background technique [0002] OTN (Optical Transport Network, Optical Transport Network) is the core technology of the transport network. OTN has rich OAM (Operation Administration and Maintenance, operation management and maintenance), powerful TCM (Tandem Connection Monitoring, tandem connection monitoring) capabilities and out-of-band FEC (Forward Error Correction, forward error correction) capability can realize flexible scheduling and management of large-capacity services. [0003] The OTN standard system defines four OTUs (Optical channel Transport Units) with fixed line rates, namely OTU1, OTU2, OTU3, and OTU4, and their line rates are 2.5G, 10G, 40G, and 100G. It is bit / s, that is, bits per second. The four OTUs respectively correspond to four ODUs (Opti...
