Optical fiber channel protocol data generation method having interactive capacity

Abstract

The invention discloses an optical fiber channel protocol data generation method having the interactive capacity. A transmitting queue is arranged for each transmitting port, and storage space is allocated for each transmitting queue; one transmitting queue is selected, and the required frame data, primitives, wait conditions or delay are inserted; the transmitting mode of the transmitting queue is set; after transmitting is started, the data in the transmitting queue are written in a DDR corresponding buffer area in turn, an FPGA reads the transmitting data in the DDR, the transmitting type is judged according to control words, and the received protocol data are waited to meet the conditions and then the subsequent data are transmitted if the judgment result indicates the wait conditions; transmitting is performed after waiting the specific time if the judgment result indicates delay; and the protocol data are packaged according to the standard frame format and then transmitted if the judgment result indicates the primitives or the frame data. The method has the feedback capacity, the specific type of frames, primitives or errors can be waited to be received and then the subsequent data are transmitted or the data are transmitted after waiting for a period of time.

Description

technical field [0001] The invention relates to a fiber channel bus protocol testing technology, belongs to the field of bus protocol testing, and in particular relates to a channel protocol data generation method with interactive capability. Background technique [0002] With its ultra-high-speed transmission rate (up to 10Gbps transmission rate), good anti-interference performance, stable transmission quality and other characteristics, fiber channel technology is widely used in aviation communication, mass data storage and other fields. Demand is high. How to simulate the data generation of actual fiber channel equipment is one of the key technologies of fiber channel bus protocol testing. In the current general fiber channel protocol test, a group of frame data or primitives are edited, and they are sent in a certain order in a loop or a single time. They do not have feedback capabilities, that is, they cannot selectively send certain frames according to the received dat...

Problems solved by technology

In the current general fiber channel protocol test, a group of frame data or primitives are edited, and they are sent in a certain order in a loop or a single time. They do not have feedback capabilities, that is, they cannot selectively send certain frames according to the received data, especially when When it is necessary to simulate some command-response high-level protocols, this simple protocol data transmission method cannot well simulate the communication situation of actual Fiber Channel devices
