Embodiment Construction

[0024] see figure 1 , the invention is a FC high-speed protocol mapping interface and its realization method.

[0025] Among them, the FC high-speed protocol mapping interface includes four functional modules: FC frame control, high-level protocol header, FC frame payload, and state machine; among them, FC frame control, high-level protocol header, and FC frame payload are respectively connected with the state machine to realize Automatic sending and receiving of FC frame control, high-layer protocol header, FC frame payload and state machine.

[0026] The present invention realizes the method for above-mentioned FC high-speed protocol mapping interface, comprises the following steps:

[0027] 1] The FC frame is processed in three parts, including FC frame control, high-level protocol header and FC frame payload; the independent control of different parts is realized through the protocol co-processing bus, and the concurrent processing capability of the hardware is increased ...

Abstract

The invention relates to a high speed protocol mapping interface and a realization method thereof, which solves the technical problems of incapability of being used in special conditions, relative redundancy in support of high layer protocol and incomplete support for some special service. The realization method has the steps as follows: performing parallel treatment on three parts of an FC frame; increasing control interfaces for the high layer protocol; increasing parts of controlling the high layer protocol in a state machine; and ensuring transparent treatment on a host interface part. The invention has higher protocol expandability, and improves organization and analysis efficiencies of the frame.

Description

technical field [0001] The invention relates to an FC high-speed protocol mapping interface and its realization method. Background technique [0002] FC communication technology is a kind of optical communication technology proposed for the requirements of storage area network, and it is widely used in the field of avionics. However, the application of FC technology in China is limited to the "black box" method, mainly because of the following points: [0003] 1. The key technologies are all controlled by some foreign communication manufacturers or technology associations, and they have imposed a technical blockade on countries or companies that do not have this technology. [0004] 2. The general FC technology is provided for the general field, and cannot be applied to special environments, such as high temperature, severe cold, vibration, corrosion and other environments. [0005] 3. In addition, the general FC technology is relatively redundant in the support of high-le...
