Virtual network mapping method

Abstract

The invention discloses a virtual network mapping method. The virtual network mapping method includes: calculating topology potential for each node in a physical network; calculating the topology potential for each node to be mapped in a virtual network; mapping the nodes in the virtual network to the nodes in the physical networks in sequence according to the topology potential obtained by calculation; mapping virtual links in the virtual network to physical links in the physical network in sequence. By the method, differences of global network information and topology locations are fully utilized during mapping, so that success rate of the mapping is improved.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a virtual network mapping method. Background technique [0002] The Internet has achieved tremendous development in the past 20 years, but at the same time it is also facing a series of problems, including scalability, security, etc., and network virtualization is considered to be an important technical means to solve the current Internet rigidity. In the cloud computing and data center network environment, network virtualization can help the network to achieve efficient resource utilization, dynamic scheduling, and effective isolation. Through abstraction, allocation, and isolation mechanisms, network virtualization selectively allocates and schedules resources, realizes simultaneous operation of multiple virtual networks on the same physical network, improves physical resource utilization, improves service quality, and reduces network energy consumption overhead and operating ...
