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...
