Multi-bus network cross-network communication method, device, system and equipment and storage medium

Abstract

The invention relates to a multi-bus network cross-network communication method, device and system, computer equipment and a storage medium. The method is applied to a multi-bus network cross-network communication system. The system comprises a network bridge and PON networks; the network bridge comprises OLT ports; the OLT ports comprise a first OLT port and a second OLT port, the PON networks comprise a first PON network and a second PON network, the first PON network corresponds to the first OLT port, and the second PON network corresponds to the second OLT port. The method comprises the following steps: receiving a data frame through a first OLT port in a network bridge, and broadcasting the data frame to a first PON network; and detecting whether the data frame needs to be transmitted to a second PON network, and if so, broadcasting the data frame to the second PON network through a second OLT port in the network bridge. Therefore, data transmission conflicts among the networks can be avoided, and interconnection communication of a plurality of PON networks is realized.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a multi-bus network cross-network communication method, device, system, equipment and storage medium. Background technique [0002] With the development of communication technology, optical network communication technology has emerged. Passive Optical Network (PON, Passive Optical Network) in optical network communication technology does not contain any electronic devices and electronic power supplies, and can avoid electromagnetic interference and lightning effects from external equipment. , reduce the failure rate of lines and external equipment, and improve system reliability. A typical PON network includes an OLT optical module and multiple ONU modules, and uses a bus, the downlink adopts the form of broadcast, and the uplink adopts the form of time-division multiplexing to realize network communication. [0003] However, in a typical PON network behavior...

AI Technical Summary

Problems solved by technology

[0003] However, in a typical PON network behavior broadcast mode, when multiple PON networks are required to communicate with each other, it will cause data transmission conflicts between networks, and it is impossible to realize the interconnection and communication of multiple PON networks.
