Embodiment Construction
[0019] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention.
[0020] refer to Figure 1-Figure 5 as shown, figure 1 It is a flow chart of a serial throughput testing method in an embodiment of the present invention, comprising the following steps:
[0021] Step 101, send data frames, the sending rate is V1, the frame length is 64B, the initial packet sending rate is 10Mbps, and it is checked whether the number of sent packets is equal to the number of received packets. If they are equal, the next packet transmission rate is adjusted to a higher order of magnitude, that is, 100Mbps; if the number of received packets is less than the number of packets sent, the next packet transmission rate is adjusted to a lower order of magnitude, that is, 1Mbps. From this it can be determined that the throughput is on the order of 10 n -10 n+1 between bps.
[0022] Step 102, the packet sending rate is adjusted...

The invention discloses a network throughput rate parallelized measuring method based on a multi-core technology. The network throughput rate parallelized measuring method comprises the steps that a serial throughput rate testing method process is determined; the whole testing process is regarded as a general task, and task decomposition is conducted to obtain multiple sub tasks; parallelized analysis is conducted on the sub tasks, targets are divided into task flow and data flow from the aspects of functions and data, task allocation is conducted on the task flow and the data flow, and test processing is conducted with an N segmentation method and a fine grit method so as to achieve the purposes of measuring high-speed network performance indexes and improving testing efficiency. According to the network throughput rate parallelized measuring method based on the multi-core technology, an existing single-core serial type network throughput rate testing method is improved, the multi-core technology is introduced, the advantage of parallelization is fully used, and accurate and efficient testing of the network throughput rate is achieved.
Description
technical field [0001] The invention relates to multi-core technology and network measurement technology, in particular to a parallel measurement method for network throughput based on multi-core technology. Background technique [0002] As of December 2013, the number of Chinese netizens reached 618 million, and the Internet penetration rate was 45.8%, which means that the Internet has become an indispensable part of people's work and life. The behavioral characteristics and performance of today's Internet have become an important part of network maintenance and operation. In order to improve the quality of network services and promote the development of the Internet and information infrastructure, it is necessary to extract and analyze network performance indicators. These indicators include network throughput, bandwidth, delay, and packet loss rate. The maximum affordability of a network or device, that is, the throughput rate, has become a very important parameter to m...
