Abstract

The invention discloses an Ethernet-oriented self-adaptive dynamic flow control system and an Ethernet-oriented self-adaptive dynamic flow control method, and belongs to the technical field of data communication. The Ethernet-oriented self-adaptive dynamic flow control system comprises a high-speed protocol processing module, a high-speed data caching module, a checking and generating module, a sending control module and a 40G Ethernet MAC module which are sequentially connected, and the 40G Ethernet MAC module is connected with opposite-end network equipment; Wherein the check and generationmodule comprises a UDP protocol packet header packaging module, an IP protocol packet header packaging module and a ping-pong cache FIFO which are sequentially connected, and the ping-pong cache FIFOis connected with the sending control module. By adopting the state monitoring algorithm and the flow control method, the frame length and the frame interval of the sent data are automatically determined, the sending data filling process is adaptively started, paused and ended, and the 40G Ethernet sending bandwidth utilization maximization is realized.

Description

【Technical field】 [0001] The invention belongs to the technical field of data communication, in particular to an Ethernet-oriented adaptive dynamic flow control system and method. 【Background technique】 [0002] In the high-performance information processing platform, optical fiber is mostly used for external high-speed interface design, 40G Ethernet is used internally for inter-blade interconnection, and FPGA chips are used to realize the conversion and data forwarding functions of optical fiber interface protocol to 40G Ethernet protocol, of which 40G Ethernet The actual transmission bandwidth utilization rate of the network directly affects the conversion efficiency and data forwarding capability of the interface protocol. [0003] The bandwidth of 40G Ethernet is 4 times that of 10G Ethernet. The higher line rate makes designers worry that 40G Ethernet will be sent too fast during the application process and the peer device will not receive it in time, resulting in packe...
