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 an FC-to-Ethernet data conversion flow control method and device, and the method comprises the steps: detecting the data flow of an Ethernet when FC data and Ethernet data areconverted; comparing the data traffic of the Ethernet with a set data traffic upper limit value; and when the data traffic of the Ethernet is judged to be greater than the set data traffic upper limit value, controlling to trigger FC data back pressure. A traditional mechanism for triggering FC data back pressure is not used any more, when FC data and Ethernet data are converted, the original mode of detecting the data flow of the FC is changed into the mode of actively detecting the data flow of the Ethernet, and when it is detected that the data flow of the Ethernet is too large, the FC data back pressure is triggered. That is to say, the FC data back pressure is triggered in advance, so that the condition of data loss during large flow is avoided, the FC data and the Ethernet data areconverted and transmitted without packet loss, and the reliability of data transmission is improved.

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...
