Embodiment Construction

[0028] In order to realize the FC-to-Ethernet data conversion flow control method of the present invention, a data conversion device is now designed.

[0029] Such as figure 1 As shown, the device includes an FPGA chip, an optical module, a power conversion chip and an Ethernet data processing chip. The device can convert two-way Ethernet signals into standard FC signals for point-to-point transmission or transmission through FC switches.

[0030] FPGA is the core processing chip of the conversion device, which is used to realize functions such as protocol conversion and status reporting between Ethernet data and FC data. The Xilinx Kintex7xc7k325t-ffg676 chip is used here.

[0031] The Ethernet data processing chip is used for signal transmission and reception, and interacts with the FPGA through the GMII interface. The 88E1111 of Marvell is used here.

[0032] The device also includes a serial port module and an indicator light module. The device can be configured throu...

Abstract

The invention relates to a data conversion flow control method and device for converting FC to Ethernet. The method detects the data flow of Ethernet when converting FC data and Ethernet data; compares the data flow of Ethernet with the set data flow The upper limit value is compared: when it is judged that the data flow of the Ethernet is greater than the set upper limit value of the data flow, the control triggers the FC data back pressure. The present invention no longer uses the traditional mechanism of triggering FC data back pressure. When FC data and Ethernet data are converted, the original detection of FC data flow is changed to active detection of Ethernet data flow. When the data traffic is too large, the FC data back pressure will be triggered. That is to say, the FC data back pressure is triggered in advance, thereby avoiding the occurrence of data loss during heavy traffic, ensuring that the conversion and transmission of FC data and Ethernet data does not lose packets, and improving the reliability of data transmission.

Description

technical field [0001] The invention belongs to the technical field of optical fiber transmission, and in particular relates to a data conversion flow control method and device for converting FC to Ethernet. Background technique [0002] FC-AE is a new type of Fiber Channel technology, featuring high bandwidth, low latency, high reliability, and high anti-interference, and has been widely used in aerospace and other fields. The FC network conforming to the FC-AE-ASM protocol has been applied to various types of products in the aviation field, providing communication support for the interconnection between the new generation of airborne subsystems. [0003] In the overall design process of the system, when using the FC network as the backbone network, taking into account the communication requirements between the functional modules in the subsystem, the amount of effective data, the compatibility of existing equipment, and the maturity of technology, etc., the Ethernet networ...
