Problems solved by technology

The currently used sequence transmission control method based on digital circuits first reads the user data in the host memory into the local cache, and then decomposes and transmits it. Although this method can realize sequence transmission control, it requires a large amount of local cache. and increased sending delay

Embodiment Construction

[0082] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific examples.

[0083] Such as figure 1 Shown, a kind of FC network sequence transmission control system and method based on digital circuit, including

[0084] 1. Configuration register group

[0085] The configuration register set consists of

[0086] 1) The S_ID register, D_ID register, frame length register, start address register, length register, timeout value register and timeout processing mode register read by the digital circuit filled by the host are all implemented by FIFO, and the FIFO depth is 32. There is a one-to-one correspondence between them. in,

[0087] a. The S_ID register stores the setting value of the S_ID field in the FC frame header;

[0088] b. The D_ID register stores the setting value of the D_ID field in the FC frame header;

[0089] c. The frame length register stores the setting value of the FC frame data load leng...

Abstract

The invention relates to an FC network sequence transmission control system and method, and especially relates to an FC network sequence transmission control system and method based on a digital circuit. The invention adopts a mode of enabling an operation of reading data from a host memory and an operation of FC frame decomposition and transmission to be simultaneously performed and controlling the transmission time of each sequence according to host configuration, only a number of local cache units with the size being 2112B are needed, load data of one FC frame is obtained from the host memory according to the host configuration if the cache units are not full, meanwhile, the load data is organized into a complete FC frame if the cache units are not empty, and the transmission time of each sequence is controlled according to the host configuration so as to finally realize transmission control for each sequence. The FC network sequence transmission control system and method based on the digital circuit not only can reduce the demand for cache and reduce the transmission delay, but also can meet the restriction of a user for the transmission channel occupation time of each sequence.

Description

technical field [0001] The present invention relates to a FC network sequence transmission control system and method, in particular to a digital circuit-based FC network sequence transmission control system and method. Background technique [0002] In the field of FC network communication, the maximum data load of an FC frame is 2112B. When the user data exceeds 2112B, the user data needs to be organized into a data structure called a sequence and sent. This sequence consists of multiple FC frames, each of which The frame header information of each FC frame marks the sequence to which it belongs and the position in the sequence, so that the receiving end can reconstruct the complete user data. Therefore, when sending a sequence, it needs to be decomposed into several FC frames according to the length of the user data and then organized and sent out. However, this sending control process is not suitable for software implementation, and is usually completed by means of digital...
