Path selection method and system, network acceleration node and network acceleration system

Abstract

The invention provides a path selection method and system, a network acceleration node and a network acceleration system. The method comprises the following steps: an inlet network acceleration node detects link delays of outlet network acceleration nodes and judges whether the outlet network acceleration nodes are available; the inlet network acceleration node obtains the link delay from the outlet network acceleration node to a source station IP from the available outlet network acceleration node; and the inlet network acceleration node selects an optimal path from the inlet network acceleration node to the source station IP according to the link delay from the inlet network acceleration node to the source station IP and the link delay from the available outlet network acceleration node to the source station IP. By adoption of the path selection method and system, the network acceleration node and the network acceleration system provided by the invention, the network acceleration node calculates the optimal path to the source station, thereby reducing the path detection number, optimizing the quality of the path selection and accelerating the path selection efficiency.

Description

technical field [0001] The invention relates to the technical field of network acceleration, in particular to a path selection method and system, a network acceleration node, and a network acceleration system. Background technique [0002] With the continuous development of computer network technology, Internet technology has become an important part of human life. Users are increasingly demanding the transmission rate of the network and the feedback speed of user requests. In the original technical architecture, the user's request data is directly sent to the origin server, and the origin server processes the user request and returns it directly to the user. Because there may be problems such as long geographical distance between the user and the origin server, different network operators, line damage, and line overload, the communication between the user and the origin server will suffer from slow transmission, slow feedback, high cost, etc. Transmission interruption and...

Problems solved by technology

[0004] However, the existing network acceleration mode has the following deficiencies: (1) When a network acceleration node receives a user request, each network acceleration node in the application acceleration network adds a new function to detect the link status between itself and the source station. Tasks and tasks that detect the link status of other network acceleration nodes. As a result, the number of detection tasks increases suddenly, and the detection traffic needs to occupy a large bandwidth, which may even affect business traffic.

(2) The huge number of detection tasks is reported to the central server, resulting in particularly heavy computing pressure on the central server, and the feedback speed is affected

As a result, although the existing application acceleration network has improved the speed and quality of data transmission between users and the source site to a certain extent, it has certain disadvantages and cannot meet the growing needs of users, nor can it provide better user experience
