Problems solved by technology

When the transmission message in the distributed system is very large, the problem of head of line blocking (Head of Line Blocking) will appear, that is, the large message blocks the transmission channel, resulting in the failure of subsequent high-priority messages to be transmitted first

Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] A system for multi-priority communication in a distributed system, such as figure 1 The following modules are shown:

[0045] Interface module: responsible for receiving communication requests from users, and submitting communication requests to the message scheduling module for scheduling communication requests.

[0046] Link management module: responsible for the creation and maintenance of virtual links, the mapping of virtual links to physical links, and the connection reconstruction operation for failed links.

[0047] Message scheduling module: responsible for implementing message scheduling for user communication requests, and implementing message fragmentation and reassembly operations.

[0048] Priority scheduling module: responsible for submitting fragmented messages after message scheduling is completed to the corresponding virtual link for ...

Abstract

The invention provides a multi-priority communication method and system of a distributed system, and provides an efficient multi-priority communication method. The method includes the steps that an interface module receives a communication request of a user and submits the communication request to a lower-layer message scheduling module; the message scheduling module schedules the message of the communication request of the user and fragments and reorganizes the message; a priority scheduling module submits message fragments to a virtual link after message scheduling is finished according to message priorities; a bottom-layer transmission module calls a bottom-layer transmission protocol to transmit the message on the virtual link. The method achieves efficient link aggregation, shields details of an underlying network, and supports various networks and various communication protocols.

Description

technical field [0001] The invention relates to a data transmission technology of a communication system, in particular to a method and system for multi-priority communication in a distributed system. Background technique [0002] The functions of the distributed system are realized through message communication between the nodes of the distributed system, so the performance and reliability of the communication system of the distributed system directly determine the quality of the service provided by the distributed system. Due to the different types of messages transmitted by the distributed system, the quality of service provided by the underlying communication system is also different; at the same time, due to the complexity of deploying the network in the distributed system, there are often multiple sets of networks of different types and protocols in one system. It is required that the communication system can well support various communication networks. [0003] In or...
