Abstract

The invention discloses a shortest path transmission method suitable for an FC-AE ring network, belongs to the technical field of ring network transmission, and aims to realize high calculation efficiency, low transmission delay and suitability for parallel calculation, and a transmission system applying the algorithm can ensure that data transmission does not form an endless loop in the ring FC-AE network. The FC-AE ring network comprises an FC-AE switch 1, an FC-AE switch 2,..., and an FC-AE switch N. The FC-AE switch 1, the FC-AE switch 2,..., and the FC-AE switch N are connected to form a closed-loop system through respective forward cascade ports, backward cascade ports, and N optical fiber cables, through a combination of offline coding and online calculation, the transmission direction with the shortest path can be quickly calculated, the transmission termination condition can be judged, and an endless loop of data transmission in the ring network is prevented.

Description

technical field [0001] The invention belongs to the technical field of ring network transmission; in particular, it relates to a shortest path transmission method suitable for FC-AE ring network. Background technique [0002] Fiber Channel Aviation Environment (FC-AE: Fiber Channel Avionics Environment) is a family of protocols developed by the Fiber Channel (Fiber Channel) standard development organization, which is used to define in detail the dedicated systems that can be used in the Fiber Channel avionics environment. The protocol organically integrates fast and reliable channel technology with flexible and scalable network technology. [0003] Fiber Channel defines three topologies: point-to-point, arbitrated ring, and switched topologies. The switched FC-AE network architecture realizes the organic interconnection of various network terminals through switches, and can facilitate network expansion. In order to realize the expansion of the switched FC-AE network, the c...
