Mirror image message transmission method in transparent interconnection of lots of link (TRILL) network and device

Abstract

The present invention discloses a mirror image message transmission method in a TRILL network and a device. The method comprises the steps of determining a remote mirror image virtual local area network (VLAN) of a corresponding source mirror image group according to a mirror image source port receiving a message when an RB device at which the mirror image source port is located receives the message from the mirror image source port; using the RB device at which the mirror image source port is located to determine a Nickname of the RB device at which a mirror image destination port is located, wherein the mirror image destination port corresponds to the remote mirror image VLAN of the source mirror image group; using the RB device at which a mirror image destination port is located to copy the message, marking the remote mirror image VLAN of the source mirror image group, and packaging into a TRILL message, and then using a TRILL distribution tree to send the TRILL message to the RB device at which the mirror image destination port is located, and finally using the RB device at which the mirror image destination port is located to forward to a corresponding data monitoring device. According to the present invention, the bandwidth resource of the mirror image message transmission is saved, and the safety of the mirror image message transmission is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for transmitting mirrored messages in a TRILL network. Background technique [0002] The TRILL (Transparent Interconnection of Lots of Link) protocol introduces the design idea of ​​the layer-3 routing technology IS-IS (Intermediate System-to-Intermediate System, intermediate system to intermediate system) into the layer-2 network, and Necessary modifications were made. In this way, the simplicity and flexibility of the second layer are organically integrated with the stability, scalability and high-tech performance of the third layer. [0003] When the source device is not directly connected to the data monitoring device, the device directly connected to the data monitoring device is used as the destination device. The source device needs to copy the mirrored message to the destination device, and then the destination device forwards the mirrored message to the ...

AI Technical Summary

Problems solved by technology

[0007] Remote mirroring packets are broadcast from the source port to the destination port through the remote mirroring VLAN in the intermediate network, causing flooding of remote mirroring packets in the network, and sometimes even seriously affecting the normal traffic transmission of the intermediate network; in addition, remote mirroring packets The text is transmitted in the network by broadcasting, which has security risks
