Abstract

The invention provides a mapping method and a mapping device for a virtual network. The mapping method comprises the following steps: performing safety capacity assessment on physical nodes in a bottom network shared by the virtual network to obtain a safety capacity matrix; based on the safety capacity matrix, determining the physical node corresponding to each virtual node in the virtual network; mapping the virtual link of each virtual node in the virtual network to a plurality of loop-free physical links corresponding to each physical node; randomly selecting one loop-free physical link from the loop-free physical links of the physical nodes, wherein the selected physical link is used for transmitting a virtual network request, that is, according to the mapping method provided by the scheme of the invention, one loop-free physical link can be randomly selected for transmitting the virtual network request during transmission of the virtual network request, the manner of randomly selecting the physical link can improve the unpredictability of link transmission, so as to improve the data transmission safety.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and more specifically relates to a virtual network mapping method and device. Background technique [0002] In order to solve the problem of network rigidity, network virtualization technology has received extensive attention from the academic community. Network virtualization technology allows multiple heterogeneous virtual networks to run simultaneously on a shared underlying network, and each virtual network is equivalent to the resources of the underlying network. Fragmentation, carrying a specific type of business. [0003] In network virtualization technology, the virtual network mapping problem is the key content of network virtualization research, which mainly completes the task of mapping virtual network requests to the idle resources of the underlying network. Since the underlying network topology in virtual network mapping is dynamically changing (mainly reflected in node / li...
