A message transmission method and device for a virtualization system

Abstract

The present application relates to the field of communication technology, and in particular to a message transmission method and device for a virtualization system. The main control device receives the first message redirected and forwarded by any expansion device, wherein the first message is the After any extension device receives the external message, it adds a header field to the external message, sets the destination device identifier in the header field as a preset virtual identifier and then encapsulates it, and determines the first When the destination device identifier in the message header of the message is a preset virtual identifier, determine the forwarding decision of the first message, and send it to the corresponding expansion device according to the forwarding decision of the first message, so that The corresponding extended device forwards based on the forwarding decision, so that the device that is not equipped with a chip supporting the 802.1BR communication standard or the device that does not support the 802.1BR communication standard can also realize vertical virtualization of centralized forwarding Function.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a message transmission method and device for a virtualization system. Background technique [0002] At present, with the development of the application of virtualization technology, the scale of the traditional data center access layer network is increasing day by day, and the number of connected servers and switches is also increasing. Since the number of ports on each switch is limited, in order to meet the access requirements of ever-increasing servers, it is necessary to continuously increase the number of switches in the network, resulting in increasing difficulty in network management. [0003] In the prior art, in order to solve the problems caused by this traditional network structure, a vertical network device virtualization system is used, but when using this system in the prior art, it is necessary to use a communication standard capable of suppo...

AI Technical Summary

Problems solved by technology

Due to the limited number of ports on each switch, in order to meet the ever-increasing access requirements of servers, it is necessary to continuously increase the number of switches in the network, which leads to increasing difficulty in network management

[0003] In the prior art, in order to solve the problems caused by this traditional network structure, a vertical network device virtualization system is used, but when using this system in the prior art, it is necessary to use a communication standard capable of supporting 802.1BR In this way, devices that are not equipped with chips that support the 802.1BR communication standard cannot realize the vertical virtualization function of centralized forwarding
