Problems solved by technology

[0003] The existing virtual network topology mapping technology generally maps a virtual network node to a physical node to realize the construction of an experimental network. However, this mapping method consumes a lot of physical network resources, especially when the required network scale is large. When the value is large, the consumption of physical network resources is greater

Abstract

The invention discloses a topology mapping method and system. The method comprises the following steps: segmenting and combining sub-graphs contained in a virtual network according to a preset simulation capability threshold, thus obtaining a plurality of sub-graphs which satisfy the preset simulation capability threshold; and mapping each sub-graph to a physical node in a physical network according to a preset mapping rule. According to the method and system disclosed by the invention, the consumption of physical network resources can be reduced.

Description

technical field [0001] The present invention relates to topology mapping technology, in particular to a topology mapping method and system. Background technique [0002] Virtual network topology mapping is the core technology of constructing large-scale experimental network by using hardware-in-the-loop simulation method. In the experimental environment, a network composed of physical devices is called a physical network, which consists of nodes and links. Node types include hosts, switches, or routers, etc., and specific hardware or software may need to be configured according to experimental requirements. The host can use network simulation or virtualization to simulate a network of a certain scale. The links refer to links of various bandwidths and delays. The virtual network topology refers to the target network that needs to be constructed on the physical network using the hardware-in-the-loop simulation method. How to select appropriate physical network resources to...
