Abstract

The invention relates to the optical communication techniques and discloses a method and a device for transmitting low-speed business signals in an optical transmission network, which leads the low-speed business signal to be mapped onto the optical transmission network with high bandwidth utilization rate, can provide a flexible scheduling mechanism and an end-to-end performance management mechanism in a level of the low-speed business signal. The method and the device for transmitting the low-speed business signal in the optical transmission network adopt a GFP mapping method for mapping the low-speed business signal (GE / FC) to an ODUGE signal which is suitable for OTN transmission; the method and the device adopt an asynchronous or synchronous multiplexing method for multiplexing the ODUGE signal in multiple ways to one-way ODUk signal; the method and the device use the mapping from ODUGE to ODUk and an ODUGE cross network for implementing the on-line and off-line business in the level of the low-speed business signal .

Description

technical field

[0001] The invention relates to the optical communication technology, in particular to the technology for transmitting low-rate service signals in the optical transmission network. Background technique

[0002] With the development of information technology, various new services are rapidly entering people's lives, especially the explosive and rapid development of services based on Internet Protocol (Internet Protocol, referred to as "IP"), which not only makes people's lives greatly changed The changes, meanwhile, have profoundly affected every aspect of the telecommunications network. At present, the number of IP users in the world will reach more than 300 million. All of this will make the data traffic, especially the IP business, gradually replace the voice traffic and become the main traffic of the telecommunication network. This will inevitably lead to the transformation of the telecommunication network from the traditional telephone network. transitio...
