The invention relates to the technology of network data processing, which aims at the defects of poor performance of a data packet generating software based on PC of the prior art, and the like, and provides a data packet generator and a data packet generating method. The data packet generator comprises an input interface, a network processor, and a network output port, wherein the input interfaceis used for receiving and transmitting data packet configuration information; the network processor is connected with the input interface, is used for receiving transmitted data packet configurationinformation and generating data packet template, copying the data packet template in a multithreading mode and transmitting the copied data packet; and the network output port is connected with the network processor and is used for receiving and transmitting the data packet transmitted by the network processor. The invention also provides a data packet generating method based on the data packet generator. The invention can meet needs of various transmitting speeds by strong processing capacity of the network processor, can be easily connected with various types of the existing network devices,has flexible programming and portability at the same time, and has low cost.
Description
technical field [0001] The invention relates to network data processing technology, more specifically, to a data packet generator and a data packet generation method. Background technique [0002] During the research and development and production process of network equipment, it is often necessary to test the performance of the network equipment (for example, the data packet forwarding speed). The testing process needs to simulate the daily working environment of the network equipment, and then test the performance of the network equipment in the simulated environment. Since the main task of the network device is to receive and forward data packets, during the test, it is necessary to use a device to generate data packets, and then send the generated data packets to the network device to be tested. This device for generating packets is a packet generator. [0003] The data packet generator on the market can be roughly divided into two classes at present, and a class is ba...
