Ring network using independent channels to transmit network management data

Abstract

The invention discloses a ring network used for transmitting network management data based on an independent channel. The ring network comprises several sites. All sites are sequentially and circularly connected through an E1 line. The E1 line contains a network management channel. Each site includes a network management site and the network management site selects one site from all the other sites. Meanwhile, the network management channel distributes or recovers a token to / from the selected site. The site with the above token is endowed with a temporary authority for being in network management data communication with the network management site through the network management channel. According to the technical scheme of the invention, a network management data transmission channel having the broadcast communication function and the point-to-point communication function is provided, and a network management site having a persistent token is determined at each site of the ring network. The network management site is used for distributing or recovering the token to / from the selected site. In this way, the selected site has the network management data communication capacity with the network management site. The transmission of a network management data packet has no effect on the transmission of a signaling data packet. Therefore, the signaling data packet can be timely transmitted, and a voice call between sites can be rapidly established.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a ring network using an independent channel to transmit network management data. Background technique [0002] Ring network stations (ring network devices) need to communicate with each other, such as picking up a phone handle to dial a number. The event of off-hook is a signaling, and the dialed number is also a signaling. These signalings are very important and need to be transmitted in time through the signaling transmission channel. [0003] In order to facilitate the management and maintenance of the ring network, the existing ring network generally adopts a centralized management method, that is, the ring network management configuration data is configured at a certain station (network management station) of the ring network, and the ring network equipment at the station will These data are distributed to various sites. At the same time, it is necessary to upload t...

AI Technical Summary

Problems solved by technology

The ring network leaves the signaling transmission channel for signaling data packets, which solves the problem that when the existing signaling transmission channel is occupied by other data, the transmission of signaling data packets is not timely, and the voice call establishment process is lengthened.
