NFV Orchestration and Rapid Migration Based on Elastic Virtual Network and Container Technology

摘要

Telcos and cloud service providers are keen to exploit virtual network functions (VNF) because it has the potential to reduce reliance on expensive proprietary networking gear and increase network elasticity. In this paper, we propose a NFV Orchestration and Rapid Migration (NORM) architecture and system to realize a complete virtual network layout through the SDN and NFV. Through the port and MAC address mapping, NORM can complete the physical nodes accessing the Virtual Networks (VNs), while deploying related VNFs through Docker. At the same time, we set up a white list function to reserve a place for the hosts to be accessed in advance to facilitate quick access from the host. Through a combination of multiple methods, NORM can support resource customization, automated deployment, and migration flexibility. We designed a complete SDN network through experiments and evaluated the relevant performance. The experimental results verified that the use of Docker compared to the VM improved three to four times in performance.
