Traffic replay method and system for network simulation environment

Abstract

The invention provides a traffic replay method and system for a network simulation environment, which can be used for carrying out traffic replay on virtual network platforms, such as analog and simulation network platforms. According to the method and the system, all communication terminals which collect the traffic from multiple interfaces are considered, a plurality of collection points of the traffic and an IP of the original traffic are mapped into nodes of the network simulation environment and the virtual network resources are fully utilized, so that the fusion of the replay traffic and the traffic generated by the network simulation environment is realized, the replay accuracy is guaranteed, the realism of the network simulation environment is improved, the total-element simulation of the environment and the behavior is realized, the method and the system support the requirements, such as scene restoration and backtracking deduction, and the application value of the traffic data is improved.

Description

technical field [0001] The invention relates to the field of virtualization and flow playback, in particular to a flow playback method and system for a network simulation environment. Background technique [0002] With the development of technologies such as virtualization and network simulation, cyberspace research that cannot be fully implemented in complex real networks, such as network security tool testing and network attack scenario construction, is increasingly carried out in a network simulation environment. What comes is whether the network simulation environment can improve its authenticity as much as possible to provide a research platform that is as credible as possible for related research tests. [0003] Corresponding traffic support is required in the network simulation environment, which is mainly reflected in the following aspects: [0004] 1) A network simulation environment that does not adopt full physical deployment must have a certain degree of virtual...

Problems solved by technology

[0005] 2) The core elements of the actual network are the environment and behavior. At present, the construction of a network simulation environment focuses more on the simulation of the network environment itself, and lacks the behavior simulation in the network environment, which makes it difficult to meet the refined and personalized application requirements

[0016] Although the above tools are different in playback granularity and playback level, their common feature is to use a single machine to directly playback Layer 2 network packets, or use dual network cards or multiple server-side network cards to distinguish the client from the server at the transport layer Perform traffic playback, but in essence, the above methods do not consider the actual network communication environment. For the network simulation environment, virtual network resources cannot be used, and the playback traffic cannot be better integrated with the traffic generated by the virtual network. Cannot be directly used in network simulation environment

Chinese patent ZL 201310253417.4 designed a virtual network traffic playback method based on IP mapping, but the input traffic must be collected from a single interface, and the playback of multi-interface collected traffic in the network simulation environment cannot be processed, and the adaptability is poor. And it does not propose how to guarantee the timing of playback to ensure the correctness of playback
