A message transmission method and apparatus

Abstract

A message transmission method and apparatus are provided. In this scheme, an access component in a communication device, when determining that a message needs to be transmitted to a target hardware device in other communication devices, translates a storage address of a virtual hardware device in the message to a storage address of the target hardware device, and translates a storage address of amemory of a processor in the message to a storage address indicative of the target hardware device. Thus, when the access component in the other communication device receives the message, the target hardware device may transmit a message to the target hardware device directly according to a storage address indicating the target hardware device, instead of operating through a processor of the communication device, so that the target hardware device may complete an operation of reading or writing the target data according to the storage address contained in the message. The target hardware device may transmit a message to the target hardware device directly according to a storage address indicating the target hardware device. The scheme can save the computing resources of the processor in the communication device where the target hardware device is located, and can also reduce the access delay of the communication device to the target hardware device located in other communication devices.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message transmission method and device. Background technique [0002] At present, in order to realize the rational utilization of resources, resource integration technology is a research direction in the development of communication technology. For example, in cloud computing, distributed computing, virtual machines, etc., resource integration technologies will be adopted. [0003] A communication system using resource integration technology can use the hardware resources in at least one resource device as a logical hardware resource pool, and then allocate the hardware resources in the hardware resource pool to different application devices according to the needs of different application devices . Wherein, the hardware resources may include, but are not limited to, at least one of the following: storage resources, network resources, video processing reso...

AI Technical Summary

Problems solved by technology

[0015] From the above process, it can be seen that the access of the application device to the remote hardware resource requires the participation of CPU b in the remote resource device, which not only consumes the processing power of CPU b, but also increases the access delay of the application device to the hardware resource.
