Networking method of monitoring ring network and networking device thereof

Abstract

The embodiment of the invention discloses a networking method of a monitoring ring network and a networking device thereof. According to the networking method, networking of a monitoring ring network system is realized through one ring network switch and multiple common switches, and transmission of a multicast / broadcast message of which the source address is a gateway equipment MAC address is timely performed through an auxiliary port in case of disconnection so that the common switches influenced by disconnection are enabled to transmit monitoring data flow to the auxiliary port, and thus loss of the monitoring data flow in case of disconnection of the loop can be avoided. According to the networking method, reliable transmission of the monitoring data flow can be guaranteed through one ring network switch, and networking of the monitoring ring network system does not need to be performed by completely using the ring network switches so that the low-cost common switches and the existing common switches of users are enabled to be compatible by the monitoring ring network system, and waste of existing equipment can be avoided. Meanwhile, unification of a ring network protocol can also be guaranteed by the networking structure having only one ring network switch so that the networking difficulty and cost of the monitoring ring network system can be reduced.

Description

technical field [0001] The present application relates to the field of monitoring data transmission, in particular to a networking method and device for monitoring a ring network. Background technique [0002] The monitoring system is one of the most widely used systems in the security system. With the development of the monitoring industry, more and more places need to install the monitoring system. Among them, when monitoring the perimeter of parks or airports, the monitoring network often uses ring network technology to provide link reliability and save optical fibers. [0003] like figure 1 As shown in FIG. 2 , it is a schematic diagram of a ring network networking manner in the prior art. The ring network switch uses optical fibers to form a ring network. The network camera is connected to the ring network switch with a network cable. [0004] During the process of implementing the present application, the applicant found that the above-mentioned existing solutions ...
