Abstract

An embodiment of the invention provides a method and a device for optical network data transmission. The method includes slicing a data frame of STM-1 (synchronous transport module level 1) type or STS-1 (synchronous transport signal level 1) to obtain a plurality of cells equal in length; and performing cross scheduling to the cells serving as cross grain size. The data frame of the STM-1 type or the STS-1 type is sliced to obtain the cells equal in length, and the cells serve as cross grain size to perform cross scheduling, so that a cross board can be shared to allow for unification of cross scheduling, complexity of cross scheduling is lowered and cost is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communications, and more specifically, to a method and device for optical network data transmission. Background technique [0002] With the rapid growth of multimedia services, the transmission capacity and capacity of the information transmission network are required to be larger and larger. The development of optical fiber technology has greatly promoted the development of digital communication technology to meet people's demand for bandwidth. SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) / SONET (Synchronous Optical Network, Synchronous Optical Network) is the main network in the optical network. SONET is a North American regional standard, and SDH is an international standard based on SONET. [0003] SDH / SONET defines a set of rates and formats for transmitting optical signals on optical fibers. STM-N (Synchronous Transport Module Level N, Nth-level synchronou...
