Embodiment 1

[0030] This embodiment provides an RRPP ring network topology transmission method, which uses the unique IRF2 (Intelligent Resilient Framework 2, second-generation intelligent elastic architecture) technology of Huasan Communication Technology Co., Ltd. to virtualize two aggregation devices into one device (Such as figure 1 ), thus simplifying the RRPP networking.

[0031] Among the IRF2 virtualized devices, one of them is the Master device, which is responsible for the management of the entire virtualization architecture; the other devices are Slave devices, which operate as the backup devices of the Master device, and the virtualized devices are connected through optical fibers. Such as image 3 As shown, the virtual device formed after IRF of the box-type device is equivalent to a frame-type distributed device. The Master device is equivalent to the main main control board of the virtual device, and the Slave device is equivalent to the standby main character of).

Embodiment 2

[0037] This embodiment provides an RRPP ring network topology transmission system obtained by the RRPP ring network topology transmission method described in Embodiment 1, such as figure 2 As shown: the two aggregation devices C and D are virtualized into one device through IRF2 technology, and access node A and access node B are respectively connected to C and D through two links, and through IRF2 of C and D, this Cross-device link aggregation is used to bind the two links to avoid RRPP convergence caused by a single point of failure on the aggregation device.

[0038] In an RRPP networking environment (such as figure 1), although the two aggregation nodes are virtualized into one device through IRF2, when one of the physical nodes fails, even under the action of IRF2, the other aggregation node can be the backup of the failed node, but RRPP will still detect The link on the ring connecting the faulty node is interrupted, causing RRPP to converge. In order to avoid this si...

Abstract

The invention discloses a rapid ring protection protocol (RRPP) ring network topology transmission system and a transmission method. The transmission method is characterized in that a ring network topology structure comprises a sink node and a plurality of ring networks arranged under the sink node, wherein the sink node consists of a plurality of sink facilities, and the sink facilities are virtualized into one facility, i.e. a virtualized facility through the second generation of intelligent resilient framework technology in the transmission method. In the invention, the network framework is simplified on the premise without reducing the reliability of double sink facilities, the fast switching of services is ensured, and the network reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of network topology, and relates to an RRPP ring network topology transmission system and a transmission method. Background technique [0002] In actual networking applications, in order to provide high reliability at the access layer, the ring network technology can be used. In order to avoid broadcast storms in the ring network, the generally used STP (Spanning Tree Protocol, Spanning Tree Protocol) protocol loop protection mechanism can be used initially. However, in practical applications, the convergence time of the STP protocol is affected by the network topology, and the convergence time is longer when the network diameter is large, so it often cannot meet the requirements of high-quality data transmission. In order to shorten the convergence time of the ring network and eliminate the impact of the network size, the RRPP protocol developed by Huasan Communication Technology Co., Ltd. can be used. ...
