Fast ring network method against attack based on RRPP, apparatus and system

Abstract

The method comprises: receiving the PRPPP message carrying authentication; reading out the authentication message in PRPPP message; comparing it with the local authentication information; if they are identical, then processing the PRPPP message; otherwise, abandoning the PRPPP message. The device thereof comprises: a PRPPP message receiving module carrying the authentication information; a PRPPP message processing module for reading and processing the PRPPP message. The system thereof comprises: a first node for sending the PRPPP message carrying the authentication message and a second node for receiving, reading and processing the PRPPP message.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an RRPP-based fast ring network attack prevention method, device and system. Background technique [0002] RRPP (Rapid Ring Protection Protocol, Rapid Ring Protection Protocol) is a link layer protocol specially applied to Ethernet rings. It can prevent the broadcast storm caused by the data ring when the Ethernet ring is complete, and can quickly activate the backup link to restore the communication path between the nodes on the ring network when a link on the Ethernet ring is disconnected. [0003] Each switch on the Ethernet ring is called a node, and each RRPP ring has one and only one master node, which is the main decision-making and control node on the RRPP ring. All nodes on the RRPP ring except the master node can be called transit nodes. The master node is the initiator of the Polling mechanism (active detection mechanism of the ring network status), and also the ...
