Problems solved by technology

Therefore, many of the existing implementation methods are subject to the limitations of the product architecture, and there are many defects. For example, VNFs are deployed on different physical hosts, which leads to data transmission delays and memory access delays due to cross-physical nodes, reducing VNF instances. increase the speed, increase the time consumption of file transfer, and also lead to the waste of resources caused by repeated storage of files

Abstract

The embodiment of the invention discloses a method and device for quickly instantiating a VNF according to an affinity principle, and provides a scheme for effectively improving the instantiation speed of the VNF. An affinity deployment scheme is provided, and a logic management relationship is established between the virtual resources required by the VNF and the actual physical host resources through the method, so that the VNF is deployed on the same physical host, and the data transmission delay and the memory access delay caused by the cross-physical nodes are reduced. By providing a mirror image file sharing pool management scheme, the file transmission time consumption is reduced, and the resource waste caused by the repeated file storage is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method and device for quickly instantiating a VNF according to the principle of affinity. Background technique [0002] In the 5G NFV (Network Function Virtualization, network function virtualization) network architecture, how to quickly and efficiently instantiate VNF (Virtualized Network Function, virtualized network function) is one of the indicators for testing the quality of a system solution. Since VNF instantiation is an architecture-level solution, it involves multiple network element functions and even cross-vendor products. Therefore, many of the existing implementation methods are subject to the limitations of the product architecture, and there are many defects. For example, VNFs are deployed on different physical hosts, which leads to data transmission delays and memory access delays due to cross-physical nodes, reducing VNF instances. It in...
