Abstract

The invention discloses an Ethernet-oriented adaptive dynamic flow control system and method, belonging to the technical field of data communication. Ethernet MAC module, the 40G Ethernet MAC module is connected to the peer network device; the checksum generation module includes a UDP protocol packet header encapsulation module, an IP protocol packet header encapsulation module and a ping-pong cache FIFO, which are connected in sequence, and a ping-pong cache FIFO and a transmission control module connect. By adopting the state monitoring algorithm and flow control method, the frame length and frame interval of the transmitted data are automatically determined, and the filling process of the transmitted data is adaptively started, paused, and terminated, so as to maximize the utilization of the transmission bandwidth of 40G Ethernet.

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 fibers are 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 from optical fiber interface protocols to 40G Ethernet protocols. 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 send too fast during the application process and the peer device will not receive it in time, resulting in packet loss. Therefore, ...
