Problems solved by technology

In a communication network based on the TCP / IP protocol, the loss of data packets is generally attributed to network congestion. Therefore, after packet loss is found, the source node reduces the sending window (such as reducing the sending rate to half of the original ), and resend the lost data packets to the destination end node through the reduced sending window, which will further prolong the round-trip delay of the data transmission of the satellite network

Abstract

The invention discloses an intermediate node, a communication network and a data transmission control method. The data transmission control method comprises the steps of: analyzing an MAC (Media Access Control) address of a port of a former node for sending a data packet, which is carried in the data packet, and analyzing a node sequence number distributed for the data packet by the former node after the intermediate node receives one data packet; carrying out corresponding recording on the analyzed MAC address and the analyzed node sequence number; finding each node sequence number recorded corresponding to the MAC address by aiming at the MAC address of each record when the intermediate node arrives in each confirmation period so as to determine a maximum node sequence number and a node sequence number of a lost data packet; turning back a confirmation message carrying with the determined node sequence number to the former node; determining the data packet received by the intermediate node by the former node based on the received confirmation message, and removing the determined data packet from a corresponding queue of the intermediate node. By application of the data transmission control method, the data transmission quality can be improved.

Description

technical field [0001] The invention relates to the Internet field, in particular to an intermediate node, a communication network and a data transmission control method thereof. Background technique [0002] The communication controller is called a network node in the communication network. On the one hand, the network node serves as an interface connecting the host and terminal of the resource subnet, connecting the host and terminal into the network; on the other hand, the network node serves as a communication The packet storage and forwarding node in the subnet completes the functions of packet reception, verification, storage and forwarding, etc., and realizes the function of sending the data packet of the source host to the destination host. Network nodes can include network terminals, workstations (which can be personal computers or servers) and intermediate routers. [0003] A communication network is composed of several network nodes, and the network nodes include...
