The invention discloses a method and device for transmitting a message. The burden of an interface node can be reduced. The method is applied to a communication system comprising a first network and a second network, wherein the first network comprises a first node and a second node, and the second network comprises a third node and a fourth node; the message is transmitted between the first node and the second node based on a first communication protocol, and the message is transmitted between the third node and the fourth node based on a second communication protocol; the method comprises the following steps: the first node acquires target service data needing to be transmitted to a second network, and the first node is an access node of the target service data; the first node encapsulates the target service data according to the second communication protocol so as to generate a first message; the first node encapsulates the first message according to the first communication protocol so as to generate a second message; and the first node sends the second message to the second node.
Description
technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for transmitting messages. Background technique [0002] With the development of network technology, Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) network is gradually replaced by Packet Switched Network (PSN, Packet Switched Network). Transmission through the SDH network and PSN requires the connection between the SDH network and the PSN to jointly complete the transmission of service data. During the docking process, the service data that needs to be transmitted to the SDH network in the entire PSN must first be transmitted to the interface node between the PSN and the SDH network. After the interface node recovers the service data, it completes the service data according to the communication protocol of the SDH network. The mapping, multiplexing and other processing processes can be sent to the SDH network. ...
