Problems solved by technology

When the system is in this state, the command issued by the main control process (such as the Master process) to the work process (such as the Worker process) cannot be executed, or the work process cannot tell the execution result of the task to the main control process; because the main control process It is believed that the working process is still running normally, which leads to the execution task of the master process end being unable to end for a long time, and the task is put on hold, seriously affecting the normal operation of the system

Embodiment 1

[0067] In a distributed system, programs usually run on different nodes, and the communication between processes or programs is generally divided into two categories: 1. Heartbeat communication, which synchronizes the status of the other party through periodic heartbeat messages; 2. Data communication, sending Data content related to user logic, such as executed task instructions, results of instruction execution, etc. The network link for heartbeat communication may be called a heartbeat channel, and the network link for data communication may be called a data channel. In this embodiment, the communication channel includes but not limited to: a heartbeat channel and a data channel between the master control process and the working process.

[0068] refer to figure 1 , shows a flowchart of steps of a method for processing a communication channel in Embodiment 1 of the present application. In this embodiment, the communication channel processing method includes:

Embodiment 2

[0078] In a distributed system, the Master-Worker mode is one of the commonly used parallel modes. The core idea of ​​the Master-Worker mode is: the Master process and the Worker process in the system work together. Among them, the Master process is responsible for receiving and assigning tasks; the Worker process is responsible for processing tasks. After the task processing is completed, the Worker process can return the task processing results to the Master process, and the Master process can summarize the processing results returned by the Worker process. In this embodiment, the master control process and the worker process may respectively correspond to a Master process and a Worker process. The communication channel between the master control process and the working process may include: a heartbeat channel and a data channel.

[0079] refer to figure 2 , shows a flowchart of steps of a communication channel processing method in Embodiment 2 of the present application....

Embodiment 3

[0101] In combination with the foregoing embodiments, this embodiment uses a specific example to describe the communication channel processing method in detail.

[0102] refer to image 3 , which shows a communication architecture diagram between a Master process and a Worker process in Embodiment 3 of the present application.

[0103] In this embodiment, the Worker process end and the Master process end in the distributed system respectively include a heartbeat channel module (HB module) and a data channel module (PM module).

[0104] Among them, the HB module is used to maintain the heartbeat channel, such as, image 3 The channel 1 in the channel 1 is used to transmit the heartbeat message (HB message). PM module for establishing and maintaining data channels such as, image 3 The channels 2 and 3 in the channel are used to send and receive data messages (PB messages).

[0105] In this embodiment, one heartbeat channel can be maintained by the HB module and multiple dat...

Abstract

The embodiment of the present application provides a communication channel processing method and system, wherein the communication channel includes: a heartbeat channel and a data channel between the main control process and the working process, and the method includes: determining that there is an association relationship with the heartbeat channel at least one data channel; detect the at least one determined data channel; when any data channel is detected to be disconnected, disconnect the heartbeat channel so that the heartbeat times out; after determining the heartbeat timeout, end current task. The embodiment of the present application ensures the consistency of the state of the data channel and the heartbeat channel, avoiding the problem of tasks being suspended for a long time and being unable to be executed, as well as the occupation of system resources.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a communication channel processing method and a communication channel processing system. Background technique [0002] In a distributed system, programs usually run on different nodes. The communication between programs is generally divided into two categories, first, heartbeat communication, which synchronizes the state of the other party through periodic heartbeat signals; second, data communication, which sends content related to user logic, such as the executed task instructions and the results of instruction execution . The network link for heartbeat communication is called a heartbeat channel; the network link for data communication is called a data channel. [0003] In the actual operation and maintenance process of the product, especially when the pressure on the cluster network is high, some or all data channels may be disconnected but the heartbea...
