Embodiment Construction
[0028] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
[0029] See figure 1 , figure 1 A method for allocating access requests provided by an embodiment of the present invention, applied to a load balancing device, includes:
[0030] Step 101, detecting whether the first server in the server cluster is in a normal working state;
[0031] The above load balancing device and the server cluster may belong to the same service platform, and the server cluster may include multiple servers, and the load balancing device may establish a connection with any server in the server cluster, and based on the established connection, perform data transmission. Users who use the services provided by the service platform usually establish connections with servers in the server cluster through load balancing devices. Forwarded to each server in the server cluster. Wherein...

The embodiment of the invention provides an access request distribution method, load balancing equipment and electronic equipment. The method comprises the following steps: detecting whether a first server in a server cluster is in a normal working state; if yes, sending a first access request to the first server; if not, sending the first access request to a second server in the server cluster; under the condition that it is detected that the first server is not in the normal working state, detecting the number of connections kept by the first server every other preset duration; and when thenumber of connections retained by the first server is smaller than a preset value, disconnecting all connections retained by the first server, and removing the first server from the server cluster. The access request allocation method, the load balancing equipment and the electronic equipment provided by the embodiment of the invention can solve the problem of poor allocation effect when the loadbalancing device allocates the access request to the back-end server in the prior art.
Description
technical field [0001] The invention relates to the technical field of network communication, and relates to an access request distribution method, load balancing equipment and electronic equipment. Background technique [0002] In the prior art, as a data forwarding medium, a load balancing device is usually used to connect a client and multiple backend servers, and forward the received access request from the client to the corresponding server. However, when the load balancing device allocates access requests to the back-end servers, it usually judges whether the number of connections currently held by the back-end servers is saturated, and randomly distributes the received access requests to the servers whose connections are not saturated. server, however, when a certain back-end server is currently down, if an access request is sent to the server, the problem of access failure will result. It can be seen that in the prior art, the load balancing device is distributing ac...
