Abstract

A service data transmission method for optical network includes such steps as determining the net load unit of optical channel adaptive to the total bandwidth of GE service data according to the number of GE service data channels to be transmitted, dividing the net load domain of said net load unit into the time slots relative to said number of data channels, packing the GE service data into frames, transmitting them over optical network, receiving them by receiver, decomposing to obtain frames, and unpacking the frames to obtain the GE service data. Its transmission device is also disclosed.

Description

technical field

[0001] The present invention relates to the field of optical transport network, and more specifically, the present invention relates to a service data transmission method and device for transmitting Gigabit Ethernet (GE, Gigabit Ethernet) services on an optical transport network. Background technique

[0002] Generally, an Optical Transport Network (OTN, Optical Transport Network) is defined as an optical network with advanced features, such as optical channel routing, switching, monitoring, and survivability, and can be extended to a maximum bandwidth of each optical channel tens of Gbps) flexibly, scalable, and reliably transport a wide range of client signals. In a full-featured optical transport network, transport network functions will shift from SONET / SDH networks to optical transport networks, and supplement service layer features to meet a wide range of infrastructure and specific service requirements.

[0003] refer to figure 1 , which is a schemat...
