Problems solved by technology

[0006] Usually, in the avionics network, each terminal node needs to be configured with multiple ports. If multiple discrete single-port airborne FC network data emulation cards are combined to realize multi-channel data transmission, it will be difficult to implement in network layout, and the weight and cost increase

Abstract

The invention discloses a data channel scheduling method of a multichannel FC network data simulation system, comprising that: a standard FIFO port is provided by configuring a plurality of asynchronous printed circuit boards on one side of a PCIE management module of an FC network data simulated card, a DMA caching module is configured on each channel of one side of a PC, and the DMA caching module realizes bidirection multichannel transmission of the asynchronous printed circuit board FIFO and the PC through the PCIE management module. As a result, that a plurality of optical ports are arranged on the FC simulation card can be realized, which reduces the cost for information multichannel transmission and supports the port redundant.

Description

technical field [0001] The invention belongs to the technical field of network communication, and more specifically relates to a data channel scheduling method of a multi-channel FC network data simulation system. Background technique [0002] With the deepening of integration, the use of a unified optical interconnection network has become an inevitable trend for the internal interconnection of avionics systems. Airborne Fiber Channel (FC) network has become the mainstream choice for airborne avionics network design due to its advantages of high reliability, low cost, high speed, strong real-time performance, and good scalability. Airborne optical fiber network technology will be more widely used in the field of avionics. [0003] At present, many companies and scientific research institutes in the world, such as IBM, HP, DELL, Brocade, Qlogic, Huawei, etc., have participated in the research and development of a series of equipment based on the Fiber Channel protocol, and ...
