Abstract

The invention discloses an FPGA (field programmable gate array) network flow generating system and method based on a multifractal wavelet model. The generating system comprises a first PCI host, an Ethernet input interface, a first MAC address input queue, a user data path, a second MAC address input queue, an Ethernet output interface and a second PCI host in sequence; the signal of the first PCI host is sent to a register input-output interface, the register input-output interface and an SRAM register are subjected to bidirectional communication, the user data path further comprises a data package generating module, a data arbitrating conversion module, an output end inquiring module, a multifractal wavelet model control module and an output queue module, which are connected in sequence, the data package generating module receives the data of the first MAC address input queue, and data of the output queue module is sent to the second MAC address input queue. The FPGA network flow generating system and method based on the multifractal wavelet model solve the problem that the traditional flow generating system cannot simulate the actual network background flow, and are matched with actual network flow characteristics and used for development of network new application, network flow analyzing and network equipment testing.

Description

technical field [0001] The invention relates to a system and method for generating FPGA network traffic based on a multifractal wavelet model. Background technique [0002] When performing Ethernet testing, the assistance of a traffic generator is often needed, for example: applying a predetermined size of traffic on a network segment to test the error of the network segment; ) traffic to test the network error reporting function; use the remote device detection function to test the single-ended throughput; simulate additional users; verify the statistics of the switch port traffic, etc. A traffic generator is a tool that can generate frames of a specific type, specific length, and specific rate, and collect statistics on parameters such as the overall traffic and utilization of the network. [0003] The application types of the Internet have their own statistical characteristics. Classifying and analyzing the network according to these characteristics can effectively contr...
