Problems solved by technology

[0004] However, in the above-mentioned method for reducing the jitter of sensitive service messages, each slice of the data service message needs to be encapsulated with MLPPP (Multilink point-to-point protocol, Multilink point-to-point protocol) before sending, so that Each slice will increase the encapsulation overhead by an average of 11 bytes. When the data service message is transmitted through the physical port on the sending / receiving device, it will significantly reduce the bandwidth utilization of the communication link, resulting in the reduction of the sensitive service message. The text dithering method cannot be used in the field of microwave communication, which requires a relatively high bandwidth utilization.

Embodiment 1

[0026] This embodiment provides a method for sending a service message. The execution body of the method is a sending device with a message sending function in a communication network, and the sending device includes a network communication device capable of running a data link layer protocol (for example, a two layer switch), such as figure 1 As shown, the method includes the following steps.

[0027] 101. Receive non-sensitive service packets.

[0028] Specifically, the sending device receives a non-sensitive service message, which needs to be sent to the receiving device through the sending device. In order to prevent the jitter effect caused by sending the non-sensitive service message on the sensitive service message, it is necessary to Carry out the slicing processing in the subsequent steps, and then send the slice to the receiving device of the non-sensitive service message through the physical port of the sending device via the communication link.

Abstract

Disclosed in the embodiments of the present invention are a method for transmission and reception of traffic packets, a device, and a system, applying to the technical field of network communications. The method, device and system resolve problems in current methods to decrease sensitive traffic packet jitter which significantly decreases the broadband utilization rate of communication links. In the embodiment of the present invention, as a result of cutting non-sensitive traffic packets into sections before transmitting them, the method can combine non-sensitive traffic packets and sensitive traffic packets before transmission, thereby decreasing jitter in sensitive traffic packets; when cutting the non-sensitive traffic packets into sections and before starting the section processing, first a modulation mode of the communication link is obtained, said modulation mode being determined by an adaptive coding and modulation engine and reflecting a current packet transmission quality, then the current section length is calculated and obtained in order to guarantee the maximization of transmission of traffic packets. Therefore, the bandwidth utilization rate of the communication link is increased while ensuring that sensitive traffic packet jitter is reduced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, device and system for sending and receiving business messages. Background technique [0002] The main feature of the frame relay network is that it adopts the asynchronous multiplexing technology based on the variable length frame, and the transmission rate of the data service message is high. When delay-sensitive service messages such as voice and video (hereinafter referred to as sensitive service messages) are mixed with data service messages, competition occurs between the two types of service messages. If the data service message is preferentially transmitted, and the data service message is long (for example, a jumbo frame), the sensitive service message needs to wait for the data service message to be sent before it can be sent. This waiting time (usually is 8ms) is unacceptable for sensitive service packets, resulting in jitter of sensitive servic...
