Abstract

An embodiment of the invention provides a method and a device for transmitting inter-domain interface data in an optical transport network. The method comprises the steps of: determining a rate of an inter-domain interface signal data frame according to traffic of service to be transmitted; encapsulating the service to be transmitted into the inter-domain interface signal data frame; and transmitting the encapsulated inter-domain interface signal data frame. The method and the device for transmitting inter-domain interface data in the optical transport network can unify a client interface format and simplify processing in transmission equipment or routing equipment, thereby reducing implementation cost of the entire network, and realizing end-to-end bandwidth linkage adjustment of the routing equipment and the transmission equipment.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and device for inter-domain interface data transmission of an optical transport network. Background technique [0002] Optical transport network (OTN), as one of the mainstream transport technologies, has the ability to carry and transport multiple services. For example, SDH services, Ethernet services, CPRI services, FC services, and high-definition video services can all be carried out through the optical transport network. Bearer transfer. In particular, the Ethernet service is one of the main customer services carried by the current OTN. With the birth of 400GE, it drives the evolution of OTN to a higher rate. Bandwidth delivery requirements. [0003] With the increase of the OTN rate, the type and quantity of services carried are also increasing, which also brings certain problems. The reason is that before being carried by OTN, it is necessary ...
