A packet fragmentation method and device for vsm channel

Abstract

The invention provides a message fragmentation method and a message fragmentation device for a VSM channel. The message fragmentation method comprises the steps that: buffering target data which is uploaded by a local target service module and needs to be transmitted to opposite-end VSM member equipment in a message buffering region corresponding to the VSM channel by means of local-end VSM member equipment; judging whether the target data needs to be fragmented based on preconfigured MTU; if so, fragmenting the target data and transmitting the fragmented message to the opposite-end VSM member equipment via the VSM channel; and assembling the received fragmented message corresponding to the target data by means of the opposite-end VSM member equipment, and uploading the target data obtained through assembly to a local service module corresponding to the target service module. The message fragmentation method and the message fragmentation device solve the problem that a communication mechanism of independent service modules is not conducive to the stability of the whole VSM system.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for fragmenting messages of a VSM channel. Background technique [0002] VSM (Virtual Switch Matrix) is a new network device virtualization technology that virtualizes multiple network devices into one network device. In a VSM environment, there are multiple member devices, and the network links between member devices are called VSM channels. Data packets and protocol packets can be transmitted between member devices through VSM channels. Each member device is divided into multiple business modules according to their functions. The same type of business modules of each member device will communicate with each other. When the amount of data is large, each business module will split its own data and send it out. [0003] In the prior art, each business module fragments the interaction information according to its own mechanism, and each bus...
