Method, device and system for controlling data traffic as well as gateway equipment and switchboard equipment

Abstract

The invention discloses a method, a device and a system for controlling data traffic as well as gateway equipment and switchboard equipment. The method comprises the following steps: establishing and keeping communication with the gateway equipment; during the process of keeping communication, receiving an access control list (ACL) configuration command from the gateway equipment, wherein the ACL configuration command carries quinary group information comprising a source address, a source port, a destination address, a destination port and protocol type of data stream; determining the port for forwarding the data stream according to the quinary group information; configuring the ACL of the determined port according to the received ACL configuration command; and limiting the data stream indicated by the quinary group information according to the configured ACL. According to the invention, the data stream is limited on a switchboard so as to solve the problem of the prior art that excessive CPU (Central Processing Unit) resources are occupied in the even that the gateway equipment controls the data traffic.

Description

technical field [0001] The present invention relates to a network communication system, in particular to a data flow control method, device and system, a gateway device, and a switch device. Background technique [0002] Currently, in the process of network communication, an application identification mechanism and a flow control mechanism are used to transmit packets. [0003] The application identification mechanism is a technology that classifies and identifies the data flow in the network according to the application characteristics, so as to identify the application protocol type of the data flow. The identification process of application identification is mainly to analyze the packet load characteristics and packet flow characteristics of the data flow, so as to know the application protocol type of the data flow. Application identification mainly distinguishes different application services by analyzing the load characteristic string of the message, the flow characte...
