Link establishing method and device

Abstract

The embodiment of the invention provides a link establishment method and device, and the method comprises the steps: receiving an AP address list issued by a navigation server, and enabling the AP address list to comprise a plurality of AP node addresses; Selecting an AP node address from the plurality of AP node addresses as a target address, and initiating a link establishment request with a data center to an AP node corresponding to the target address; Judging whether link confirmation information of successful establishment of the data access link fed back by the data center is received within a preset time length or not; If the link confirmation information is not received, sending the link confirmation information; and if so, re-selecting one AP node address from the plurality of APnode addresses according to a preset rule to serve as the target address, and initiating a link establishment request with a data center to the AP node corresponding to the target address until link confirmation information fed back by the data center is received. The disaster tolerance of the data access link can be effectively improved, and the stability of the data access link is ensured.

Description

technical field [0001] The present invention relates to the technical field of instant messaging, in particular to a link establishment method and device. Background technique [0002] With the continuous expansion of instant messaging services, the data access links between clients and data centers are easily affected by uncertain factors such as regional differences, network fluctuations, and network delays, especially for instant messaging services in the context of global networks. Therefore, It is particularly important to establish a stable, available, and disaster-tolerant link. At present, two link establishment methods are mainly used to realize the connection between the client and the data center: [0003] (1) The client is directly connected to the data center, but this method cannot effectively avoid the negative impact of network fluctuations. [0004] (2) Use a single AP (Access Point) point to connect to the data center, and establish a dedicated line betwe...

Problems solved by technology

[0003] (1) The client is directly connected to the data center, but this method cannot effectively avoid the negative impact of network fluctuations

[0004] (2) Use a single AP (Access Point) point to connect to the data center, and establish a dedicated line between the AP point and the data center. Although this method can solve the problem of network fluctuations and link instability directly connected to the data center to a certain extent problem, but when a single AP point hangs up, the link cannot be used normally, and it is not disaster-tolerant
