Problems solved by technology

However, when the kernel-mode distributed lock component tries to establish an SCTP communication connection based on a communication IP currently obtained, it may encounter a situation where the communication connection creation operation fails due to problems such as the SCTP communication protocol creation timeout. Sometimes it will cause the problem of cluster lock blocking, and the SCTP communication connection creation process corresponding to the subsequent communication IP in the communication IP list has to be suspended

Abstract

The invention discloses a communication connection establishing method, which comprises the following steps: when a cluster management component in a cluster system starts an RRP working mode, a first kind of communication IP and a second kind of communication IP can be obtained through a user-mode distributed lock component, wherein the first kind of communication IP is the communication IP in a use state at present in the cluster system, and the second kind of communication IP is the communication IP in a non-use state at present in the cluster system; a kernel mode distributed lock component is informed to carry out corresponding SCTP communication connection establishing operation according to the first kind of communication IP; and if the connection establishing operation fails, the kernel mode distributed lock component is informed to switch the communication IP into the communication IP in the second kind of communication IP, and carry out corresponding SCTP communication connection establishing operation again according to the switched communication IP. The technical scheme can prevent the case of cluster lock blocking. The invention also discloses a communication connection establishing system and the distributed lock component.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication connection creation method, system and distributed lock component. Background technique [0002] At present, in order to ensure the stability of the cluster network, the redundant network is usually used for cluster management, that is, when the cluster management components use the RRP mode (RRP, The Totem Redundant Ring Protocol) to communicate, if a cluster network has a problem, Then you can switch to another cluster communication network to achieve network redundancy. [0003] When the cluster management component turns on the RRP mode, the kernel-mode distributed lock component will sequentially establish SCTP communication connections (SCTP, Stream Control Transmission Protocol) according to the obtained communication IP list. However, when the kernel-mode distributed lock component tries to establish an SCTP communication connection based on a comm...
