Virtual network mapping method

Abstract

The invention discloses a virtual network mapping method which includes the steps that 1, a request queue and a service gateway queue are generated; 2, whether a virtual request resource which is not mapped successfully exits or not is judged, and if yes, step 3 is executed; if not, virtual resource request mapping is ended; 3, a service gateway is selected; 4, underlying cluster selection is conducted; 5, whether virtual resource request mapping is solvable or not is judged, if yes, virtual network mapping is conducted, an underlying physical network resource state is updated, the request is deleted, and step 2 is executed; if not, step 6 is executed; 6, whether the underlying cluster range is smaller than the service gateway management region or not is judged, if yes, the underlying cluster range is broadened, and step 5 is executed; if not, the service gateway is deleted, and step 7 is executed; 7, whether the service gateway queue is empty or not, and if not, step 3 is executed; if yes, step 8 is executed; 8, whether times of queuing again exceed the preset times or not is judged, if yes, the request is rejected, and step 2 is executed; if not, the request is sent to a waiting queue, and step 2 is executed. By means of the virtual network mapping method, the mapping success number is maximized.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a virtual network mapping method. Background technique [0002] With the rapid development of science and technology and the strong drive of social demand, as well as the evolution of data production methods and the sharp drop in the cost of data generation, the data generated by humans is increasing exponentially. Due to the rapid expansion of data scale, the amount of data accumulated in all walks of life is becoming larger and larger, and the types of data are becoming more and more diverse and more complex, which has exceeded the capabilities of traditional data management systems and processing modes. So far, along with our pace of selling 5G, there is no technology for wireless link capacity that can significantly increase wireless link resources. With regard to the current available bandwidth, LTE is already close to the limit of spectrum efficiency. Therefore, ...

Problems solved by technology

However, the existing virtual network algorithm is prone to link mapping failure due to unreasonable node mapping during the link mapping process, resulting in a low success rate of virtual network mapping
