Abstract

The invention discloses a time-triggered based airborne optical network simulation system. The system comprises a configuration input and output module (1), an optical network topology configuration module (2), an optical network message configuration module (3), an optical network generation module (4), an optical network simulation module (5) and a result output display module (6). By simulating the generation of communication tasks and a running process in the airborne optical network, the airborne optical network simulation system provided by the invention solves the technical problem in the existing airborne optical network that time certainty is not provided for messages transmitted in real time in a transmission mechanism. The airborne optical network simulation system provided by the invention can add a Time-Triggered in the airborne optical network, and can make the airborne optical network have certain timeliness and can more efficiently use network bandwidth resource, so as to realize a technical effect that the airborne optical network has time certainty in transmitting message delay.

Description

technical field [0001] The invention belongs to the technical field of airborne network communication, and more particularly refers to a time-triggered airborne optical network simulation system, which is used to simulate the time-triggered information flow in the airborne optical network from generation, processing to The entire communication process received at the end. Background technique [0002] Optical network refers to the network structure using optical fiber transmission. In the optical network, it is allowed to dynamically allocate network resources to routers, which shortens the upgrade and expansion time of the service layer, and significantly increases the traffic load of service layer nodes; it has an expandable signaling capability set; fast service provision and expansion; Reduced maintenance and management operating costs; rapid optical layer service recovery capabilities; reduced requirements for operation support system software for new technology config...
