Abstract

The invention discloses a network packet sending machine based on ZYNQ. The network packet sending machine comprises a configuration circuit and a packet combining circuit, and the configuration circuit is composed of the protocol type configuration, the parameter configuration, the data link layer configuration, the network layer configuration, the transmission layer configuration and the data configuration; the packaging circuit is composed of a configuration receiving module, an MAC processing module, an ARP / RARP processing module, an IP processing module, a transmission layer processing module, an FCS verification module and an Ethernet interface module. According to the present invention, in various network testing and debugging environments, a user can flexibly customize the networkdata packets with various parameters, such as various protocol types, throughput rates, inter-frame intervals, etc. According to the hardware based on ZYNQ, the throughput rate up to 10 Gbps, the microsecond-level delay and the humanized WEB interface configuration can be conveniently achieved.

Description

technical field [0001] The invention belongs to the technical field of network communication, and relates to a ZYNQ-based network contract sending machine, which is suitable for testing and communicating with network equipment in numerous enterprises or research institutes. [0002] technical background [0003] With the further development of Internet technology, more and more network devices are developed and researched. However, in the late stage of research and development of network equipment, it is often necessary to conduct robustness and stress tests on the functions and performance of network equipment. At this point, you need to use the network contract sender. [0004] In order to meet the needs of different types of network equipment, the network contract sender is required to not only support all types of protocols, but also put forward higher requirements for the speed, throughput, operability and configurability of the contract sender. [0005] However, the c...
