Problems solved by technology

[0007] As mentioned above, the hardware load balancer used in the existing technology has the following disadvantages: (1) It does not support enough types of application layer protocols. Currently, the more common ones are only used when HTTP is used as a cluster; (2) It does not support common session mechanisms in telecommunication protocols , cannot be flexibly customized to meet load balancing; and (3) the hardware cost is relatively high

Abstract

The invention discloses a cluster administrator, a cluster system as well as a cluster management method. The cluster administrator comprises a connection managing unit, a session managing unit, a load balancing control unit and a flow control unit. The connection managing unit is used to finish the connection authentication of external systems as well as the monitoring to the successful connection; the session managing unit is used to create the connection queue for the external system request information to an internal server contact and create sessions; the load balancing control unit is used to select the ID of a down-sending node under the condition that the session managing unit inquires the request of the down-sending node; the flow control unit is used to finish the license control and the overload control of the system. The invention can allocate the session management strategy according to the information type under the cluster network organizing condition.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a cluster manager, a cluster system, and a cluster management method. Background technique [0002] In the telecom industry that requires high performance and high reliability, the basic requirement for telecom software is to support clustering. Such as figure 1 As shown, when there is a bottleneck in the performance of a single server, the cluster system can use a certain mechanism to distribute all requests to multiple node servers through the load balancer, which greatly improves the system's business processing capability. In addition, the load balancer can also monitor the availability of server nodes. For example, when one of the servers fails, access requests can be transferred to other servers that can work normally. [0003] In the prior art, a front-end hardware load balancer is mainly used to implement clustering of business systems. [0004] For example, ...
