Optical fiber network and network topology method thereof

Abstract

The invention provides an optical fiber network. The optical fiber network comprises a network controller, network terminals, and a network monitor; the network controller is networked with various network terminals to form a bus type FC network; the network monitor is arranged between the network controller and various network terminals so as to monitor network uplink and downlink communication;when the data is transmitted through network downlink communication, the network controller broadcasts a data set to each network terminal, the network terminal receives the data set and sorts out corresponding node data from the data set and executes the node data; when the data is transmitted through the network uplink communication, the node data in the data set comprises an invitation transmission instruction, so that the corresponding network terminal can executes the invitation transmission instruction and uploads the data, thereby saving a center switch which must exist in the traditional FC network, the network structure is simplified, the network building cost is lowered, the network delay of the data transmission is reduced, the wiring is simple, and the reliability is high.

Description

technical field [0001] The invention relates to an optical fiber network, in particular to an optical fiber network under a PON network framework and a network topology method thereof. Background technique [0002] The traditional fiber channel protocol Fiber Channel (FC) network topology mainly supports three types: point-to-point topology, arbitrated loop (Arbitrated Loop) and switched (Fabric topology). [0003] Although the point-to-point topology is simple in structure, it cannot be applied to large-scale networks at all. The fabric topology can support large-scale networks, but the design is quite complex and the performance requirements are high, and the communication between two nodes must pass through the fabric. Although the topology control of the arbitrated ring is simple, its reliability is low. If one node fails, the entire network will be paralyzed. [0004] Therefore, how to solve the above-mentioned problems and ensure the reliability of the networking wit...
