Embodiment Construction

[0028] In order to facilitate understanding, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. The preferred embodiment of the present invention is given in the drawings. However, the present invention can be implemented in many different forms, and is not limited to the embodiments described in this specification. Conversely, the purpose of providing these examples is to make the understanding of the disclosure of the present invention more thoroughly.

[0029] This embodiment is provided based on the flow playback method based on single network card binding multiple IP, such as figure 1 As shown, the specific content is as follows:

[0030] 1. Analyze the original PCAP file to get the minimum number of virtual machines required for playback and IP addresses that should be bound each virtual machine.

[0031] This step mainly completes IP address division and PCAP file split, such as figure 2 Indicat...

Abstract

The invention belongs to the technical field of data transmission and relates to a flow playback method in network environment testing. A flow playback method based on binding multiple IPs with a single network card, including: (1), analyzing the original pcap file to obtain the minimum number of virtual machines required for playback and the IP address that each virtual machine should be bound to; (2), converting the original Split the large pcap file into small pcap files related to each virtual machine; (3), perform binding IP and routing rule configuration on each virtual machine according to the assigned IP address; (4), on each virtual machine On the virtual machine, the pcap files assigned to the local machine will be played back according to the original relative time interval. The traffic playback method of the present invention can use relatively few virtual machines to complete a certain scale of traffic playback in the network shooting range, highly restore the traffic interaction of the real network, and better simulate the network environment.

Description

Technical field [0001] The present invention belongs to the technical field of data transmission, and the flow playback method is involved in network environment testing. Background technique [0002] In a network environment test, only the real-world scenes appear on the scene to better find problems. Problems in the network environment, basically can find problems in the analysis of traffic in the network. Therefore, reverting real network traffic has become a key step. [0003] Background flow reduction is the traffic behavior in real network scenes from the perspective of user traffic behavior. At present, the way to achieve traffic playback is mainly based on the playback of traffic characteristics and the tracking playback. The first way is mainly to produce traffic that meets the current characteristics by extracting the characteristics of network traffic, and completes the network scene restore. This mode uses a suitable model to fit certain features in real network traff...
