Problems solved by technology

But for Ethernet links, the biggest problem with this method is that it is only suitable for point-to-point direct connection scenarios, and cannot pass through switches or routers, so the application has great limitations

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0024] Before the data is sent, the present invention multiplexes at least two data messages into a packaged message and shares a message header, thereby reducing the transmission overhead of each message in an average sense and improving the line efficiency. for bandwidth utilization purposes.

[0025] In the following, the mobile communication BSS (Base Station Subsystem, base station subsystem) is taken as an example to introduce the specific implementation of the UDP package.

[0026] From figure 1 It can be seen that the Abis interface (the interface between the network element BTS of the base station system BSS and the BSC) between the network element BTS (Base Transceiver Station, base transceiver station) of the BSS and the BSC (Base Station Controller, base station controller) There are currently two types of physical layer lin...

Abstract

The invention discloses a method for sending and receiving data and a device thereof, wherein, the method for sending data comprises sending data messages. Before the data messages are sent, at least two data messages with the same transmission attributes and destination are merged to form a combined message with one message head. And the combined message is provided with a mark for identifying the combined message. The method for receiving data comprises receiving data messages. After the data messages are received, if the mark indicates the data messages are the combined message, split is implemented as follows: the message head of the combined message is taken out to be respectively filled in front of each data in the combined message to form the data messages. In the method, at least two data messages are multiplexed into a combined message, one message head is shared, and the combined message is provided with the mark for identifying the combined message. Therefore, the transport overhead for each message is averagely reduced, thus the bandwidth utilization rate of lines is improved.

Description

technical field [0001] The present invention relates to the Ethernet technology, in particular to a method and equipment for sending and receiving data. Background technique [0002] In the prior art, in the case of data packets transmitted between Ethernet network elements, when the payload is small, the overhead of the packet header is very large, resulting in a low effective utilization rate of the link bandwidth. Take the base station subsystem (BSS) of mobile communication as an example. When the Abis interface between the network element BSC of the mobile communication BSS and the BTS adopts an Ethernet link, because the service message is generally shorter, such as the VOIP (Voice over Internet Protocol in the voice message and data message, and The type of data packet transmits digital voice signals in real time on the IP data network), etc., when using UDP (User Datagram Protocol, User Datagram Protocol) messages to carry these data, it is assumed that the average ...
