The Design And Verification Of Fiber Channel Protocol Processing Module

Fiber Channel integrates the merits of both network communication technology and Channel control technology to meet the requirement of the continuous development of high speed and high-performance data transfer, which has been become a high-speed data transmission, audio and serial communication standard of video signal. Fiber channel possesses the significant advantage of low latency, good compatibility, high reliability high transmission speed and long transmission distance, thus makes fiber channel become the inevitable choice of a new generation of unites airlines electronic network. The fiber channel anonymous message protocol under the avionics environment can be applied to supporting avionic applications processors and transducer as well as communication security and low latency between the display devices. The sending the receiving process of the communication data is the basis and the key to deciding whether the protocol continues to function normally. This research design is based on the FC-AE-ASM fiber channel protocol processing module and its important significance of building a new generation of advanced integrated avionics system.Fiber channel protocol processing module is the basis of the upper mapping with FC network and the data communication. Based on the elaborate analysis of fiber channel protocol, this thesis studies the design of fiber channel protocol processing module, optical fiber channel protocol and ASM method of sending and receiving data. Finally, the thesis aims to building virtual verification environment based on the model and preliminarily validating the fiber channel protocol processing module function.The foundation of the thesis is the deep researches and analysis of framing protocol of fiber channel protocol and flow control. The development of this technology is in compliance with the FC-AE-ASM protocol to sending and receiving data under the aviation electronic environment. In accordance with the structure of the protocol and the frame to sending and receiving data process, the thesis analyzes the process of the fiber channel protocol processing module send and receive message data from these three aspects: the massage data scheduling, the organization of the data frame processing and tissue processing and the sending and receiving of the frame. In addition, the thesis proposes the overall design of fiber channel protocol module, the design principle and the working process.Based on the design and implementation of the fiber channel protocol processing module,the thesis firstly puts forward the overall validation scheme of functions of all parts in the design and analyzes the actual working environment of fiber channel protocol processing module. Then, the design of the host controller interface module, on-chips bus module and the functional model of the external FC port in the virtual environment are introduced.Next, a virtual platform for the fiber channel protocol processing module is set up by adopting the model validation method. Moreover, this thesis proves the validity of communication control information configuration, port status, the principle of link, the correctness of the credit management and message transmission and other functions in fiber channel protocol processing module.Fiber channel protocol processing module supports the upper FC-AE-ASM protocol,which can conduct the point-to-point structure or switched connections and own the ability of CRC check of frame sending and receiving. It also provides the credit management function from buffer to buffer and support queue priority scheduling of different massages and support configuration of 1GBPS and 2GBPS rate. In this thesis, the researches and the work will not only offer certain help with the domestic study of fiber channel protocol or the ASM agreement under the avionics environment and step up to the fiber channel technology breakthrough, but also will reduce the gap of overseas’ researches in this field and speed up the development and application of fiber channel products in the Chinese avionics system.
