Method and device for sending and receiving data packet in packet switched network

Abstract

The invention discloses a method for sending a data packet in a packet switched network. The method comprises following steps: classifying data packets to be sent according to a destination address; and after integrating multiple short data packets in the same class, slicing, encapsulating and sending the data packets. The invention further discloses a method for receiving the data packet in the packet switched network. The method comprises the following steps: after transmission in the packet switched network, reconstituting the received data packets, and parsing the integrated data packets obtained after reconstitution so as to obtain the short data packets in the same class. The invention further discloses a device for sending and receiving the data packet in the packet switched network. By means of the method and device, accumulated short data packets are reintegrated and encapsulated by a packet length adjusting technology, without adding consumption of system resources to form longer data packets, so as to improve the switching efficiency of the packet switched network and avoid network jitter.

Description

technical field [0001] The invention relates to the field of packet switching network technology, in particular to a method and device for sending and receiving data packets in a packet switching network. Background technique [0002] With the development of communication networks, packet switching networks are widely used in data transmission. figure 1 It is a schematic diagram of the basic structure of the packet switching network in the prior art. The handshake mechanism based on data packet request permission in the packet switching network is one of the existing technical directions for realizing packet switching. With the continuous increase of the capacity of the switching network, the degree of data congestion in the network is also increasing. The handshake mechanism based on the data packet is used to realize the switching method. Congestion occurs in the switching network, thereby reducing the consumption of cache resources. [0003] Since the packet handshake ...
