Sectioned RPC timeout value self-adaptive regulation method

Abstract

The invention discloses a sectioned RPC timeout value self-adaptive regulation method. A timeout value section is divided into a routine increasing section and a declinable section; when an RPC timeout value is positioned in the routine increasing section, the timeout value is up-regulated by adopting a multiplying method if a timeout phenomenon occurs; and after the RPC timeout value enters into the declinable section, a client-terminal communicates with a server-terminal, and the RPC timeout value is regulated via a mutual consultation mode, wherein the process is that when the timeout phenomenon occurs at the client-terminal, the RPC timeout value is regulated to be three times of the current value if the CPU of the server-terminal is in a busy state or is regulated to be two times of the current value; and if the CPU of the server-terminal is in an idle state through detection, the client-terminal is actively notified to down-regulate the RPC timeout value. The timeout value is regulated in a sectioned mode, the timeout value is regulated by fully considering the busy or idle state of the CPU of the server-terminal, and the regulation method for reducing the timeout value is provided simultaneously so that timeout value regulation is enabled to be higher in precision, regulation speed and self-adaptability.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for self-adaptive adjustment of timeout value of RPC (Remote Procedure Call, Remote Procedure Call) between partitions. Background technique [0002] In the process of communication between the client and the server of the computer network, if the client does not receive a response from the server within a certain period of time, the system calls this situation "timeout". The processing method is called "timeout mechanism". Timeout is one of the common phenomena in network services. Due to the complexity of the network, the timeout mechanism is widely used in network services. [0003] RPC protocol is an important communication technology in computer network. In RPC application, timeout mechanism is an indispensable means, which can be used to detect the failure of the system. In the RPC system, how to set a reasonable timeout value is one of the most imp...

Problems solved by technology

When the client resubmits the task (or submits a new task), the server may still execute the task that was abandoned by the client last time, and the resubmitted task (or submitted new task) cannot be executed immediately

This leads to resubmitted tasks (or new submitted tasks) waiting in queue on the server side. When more and more tasks are waiting, they will accumulate on the server side, and the waiting time of tasks is also limited. When the task exceeds the set After the specified timeout value, the task may be resubmitted, which will further increase the probability of timeout phenomenon
