Abstract
Official abstract text for this publication.
A method and apparatus for low-rate traffic signal transmission on Optical Transport Networks (OTN). The method includes: defining a frame format of the low-rate traffic optical channel data unit (ODU) signal for bearing the low-rate traffic signal; mapping the low-rate traffic signal to the low-rate traffic optical channel payload unit (OPU) of the low-rate traffic ODU signal, generating overhead bytes and filling the bytes in an overhead section of the low-rate traffic ODU to obtain the low-rate traffic ODU signal; multiplexing low-rate traffic ODU signals to an ODUk signal of which the rate matches the transmission rate rank of the OTN where the signal is transmitted, and transmitting the signal via the OTN. Based on this method, the invention provides an apparatus for the low-rate traffic signal transmission in the OTN as well. With this invention, the low-rate traffic signal transmission in the OTN can be implemented conveniently.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for transmitting a low-rate traffic signal in an Optical Transport Network (OTN), comprising: mapping a single low-rate traffic signal, for transmission on the OTN, to a single low-rate traffic Optical channel Payload Unit (OPU), wherein the single low-rate traffic OPU includes a payload that has a size of 4×3,808 bytes and a bit rate of 1,238,954.31 Kbps±20 ppm, the single low-rate traffic signal is a Gigabit Ethernet (GE) signal or a Fiber Connect…
