Abstract

The invention relates to the field of communication and discloses a control method, a control device and a computer system for data transmission. The control method comprises the following steps of: detecting the current jam parameter of each connection; determining the size of a sending window of each connection; judging that the connection is in a non-jam state at present if the jam parameter of any connection is smaller than a top jam parameter limit of the current connection, sending data of the connection according to the size of the sending window of the connection in a current control period, and returning to the step of detecting the current jam parameter of each connection; and judging that the connection is in a jam state at present if the jam parameter of any connection is equal to or greater than the top jam parameter limit of the current connection, respectively sending data of the connection according to the size of the sending window of the connection in the current control period, and returning to the step of detecting the current jam parameter of each connection. With the adoption of the technical scheme, the stability of data transmission is improved and the bandwidth utilization is increased.

Description

technical field

[0001] The invention relates to the communication field, in particular to a data transmission control method and device and a computer system. Background technique

[0002] With the development of communication technology, data transmission is an important component of the current communication network. In the network, data transmission is completed through the network sending device, and in the network topology, a network sending device is often connected to multiple peers. A network The sending device performs a data sending service for multiple connections.

[0003] figure 1 For a common structural diagram of a data transmission system that implements multiple connections on a bandwidth-limited network link, see figure 1 As shown, the network sending device (also called the root host 101) is connected to the opposite end (also called the leaf host 102), and the root host 101 and each leaf host 102 share the trunk link 103 (the trunk link 103 is relativel...
