Method for VNF Placement for Service Function Chaining optimized in the NFV Environment

摘要

The NFV environment allows more efficient acceptance of multiple users' requirements, making physical resources such as a CPU, memory, storage and network cards resourceful based on virtual machine technology. Since the service chaining technology that connects virtualized service functions sequentially as the users want and provides the service operates as different users' virtual machines construct different virtual network topologies on a fixed physical network structure, there is a problem in which inefficient service placement leads to resource waste and performance degradation in physical equipment. Thus, in this paper, a study was conducted on a method for VNF Placement to place the VNF in the optimum physical node when the present physical resource situation is monitored and SFC is generated, using an optimization algorithm with the monitored resource information.
