Embodiment Construction

[0064] Before describing the embodiments of the present invention, the meanings of some terms appearing in the present invention will be explained.

[0065] end device: A device that can connect to a network and is at the edge of the network. End devices interact with end users. The terminal device may be, for example, a PC such as a desktop personal computer (PC), a laptop computer (laptop), a tablet PC, a mobile device such as a mobile phone, a personal digital assistant (PDA), and various other Electronic devices with networking capabilities, etc. Terminal devices connected to the Internet may also be referred to as hosts because they host (run) Internet applications such as web browsers or e-mail receiving programs.

[0066] Network device: A device used as a medium to transmit data in a computer network. Examples of common network devices may include: gateways, routers, bridges, switches, hubs, repeaters, and so on.

[0067] Flow: Also known as data flow or network fl...

Abstract

The invention provides a terminal device, a QoS implementation method and a flow classifier thereof. The terminal device connected to a network comprises a QoS unit, a strategy database and a strategy implementation unit, wherein the QoS unit comprises the flow classifier which classifies a data flow to be transmitted through the network and outputs a classification result indicating the class of the data flow; the strategy database stores strategies corresponding to each class of one or more classes; and the strategy implementation unit receives the classification result from the flow classifier, searches the strategy database for finding out the strategy corresponding to the class indicating the data flow in the classification result, determines a processing operation to be carried out on the data flow at least based on the found strategy and carries out the determined processing operation on the data flow. The flow classifier can use flow feature information and flow context information. The QoS unit can also comprise a strategy control unit for receiving user input. The strategy implementation unit can use an overlay technology.

Description

technical field [0001] The present invention relates to a computer network, more specifically to a terminal device implementing QoS (Quality of Service, quality of service), a method for implementing QoS at the terminal device, and a flow classifier. Background technique [0002] Today's Internet only provides best effort service (Best Effort Service). Packets are processed as quickly as possible. This is sufficient to meet the requirements of traditional Internet services such as mail services. This type of service has no special requirements for service quality. For example, users are satisfied as long as they receive email within minutes or even hours. [0003] As the Internet develops into an information infrastructure, more and more business services are built on it. Some new services have strict quality of service requirements, which mainly include end-to-end delay, packet loss rate, end-to-end bandwidth, and jitter. For example, VoIP (Voice over Internet Protocol...
