Problems solved by technology

[0004] But in terms of packet transmission technology at present, when a certain client A starts to transmit business messages, if other clients are sending messages, then client A needs to wait for other clients to complete sending the current message before proceeding. Reclaiming the bandwidth of the virtual channel causes the packet of client A to not be sent in time. Therefore, there is an uncertain time delay when the packet is sent, and the jitter caused by the fluctuation of the time delay
In addition, when a message transmitted between a pair of clients needs to pass through many intermediate node devices on the network, every time the message passes through an intermediate node device on the network, it will cause different degrees of delay and jitter. It will lead to the accumulation of delay and jitter, resulting in a serious decline in service transmission quality
Therefore, in the process of the integration of the three networks, when the voice service is transmitted using the packet transmission technology, the above problems will cause the transmission quality of the voice service to decline, and the high-quality transmission of the voice service cannot be realized.

Embodiment 1

[0056] see image 3 , which shows a method for service transmission provided by an embodiment of the present invention, the method can be applied to a PE device at the sending end for service transmission, and the method can include:

[0057] S301: Divide the data of the service to be transmitted into blocks according to a preset length to obtain at least one data block;

[0058] S302: Encapsulate each of the data blocks according to a preset message format to obtain at least one message to be transmitted;

[0059] S303: Analyze each of the to-be-transmitted messages respectively, and determine the sending direction of each to-be-transmitted message;

[0060] S304: Scheduling the packets to be transmitted with the same sending direction and the same processing method in the same service flow, and sending the service flow to the exclusive network interface or the exclusive time slot of the network interface according to the set transmission speed.

Embodiment 2

[0107] Based on the same inventive concept of the foregoing embodiments, see Figure 7 , which shows a service transmission method provided by an embodiment of the present invention, the method can be applied to a PE device at the receiving end for service transmission, and the method can include:

[0108] S701: Decapsulate the received transmission message to obtain a data block stream carried by the transmission message;

[0109] S702: Perform reverse decoding on the data block according to the set encoding recovery strategy, to obtain a bit stream corresponding to the encoding mode of the original service data;

[0110] S703: Recover the original service data from the bit stream;

[0111] S704: Send the original service data to the client.

[0112] For the technical solution of this embodiment, it should be noted that after receiving the transmission message, refer to Figure 8 , by decapsulating, stripping off part of the content of the package, including the destinatio...

Embodiment 3

[0114] Based on the same inventive concept of the foregoing embodiments, see Figure 9 , which shows that an embodiment of the present invention provides a method flow for service transmission, and the flow can be applied to figure 1 The two PE devices in the shown network architecture are the sender PE device A and the destination PE device B respectively, and the process may include:

[0115] S901: Device A cuts the data of the service to be transmitted into blocks according to a preset length, and obtains at least one data block;

[0116] S902: Device A encapsulates each of the data blocks according to a preset message format to obtain at least one message to be transmitted;

[0117] S903: Device A respectively parses each of the to-be-transmitted messages, and determines the sending direction of each of the to-be-transmitted messages;

[0118] S904: Device A schedules the packets to be transmitted with the same sending direction and the same processing method in the same...

Abstract

The embodiment of the invention discloses a service transmission method and device and a computer storage medium. The method comprises the following steps: dicing data of a service to be transmitted according to a preset length to obtain at least one data block; respectively packaging each data block according to a preset message format to obtain at least one message to be transmitted; analyzing each message to be transmitted, and determining a sending direction of each message to be transmitted; and scheduling the messages to be transmitted with the same sending direction and the same processing mode in the same service flow, and sending the service flow to the exclusive network interface or the exclusive time slot of the network interface according to a set transmission speed.

Description

technical field [0001] The present invention relates to communication technology, in particular to a service transmission method, equipment and computer storage medium. Background technique [0002] With the development of communication technology, the Internet, cable TV network and telecommunication network are integrated with each other and gradually form a unified network system. Among these three types of networks, the transmission technology of the telecommunication network needs to change from Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) technology to Ethernet technology based on packet transmission technology. [0003] For SDH technology, it is a circuit transmission technology. Specifically, a dedicated and exclusive circuit channel is established between two clients to transmit information. Its advantages are short transmission delay time, small delay jitter, and high reliability. High, very suitable for the transmission of voice services; but...
