An uncoupled and lightweight Virtualized Network Function Controller
首发时间:2019-02-01
Abstract:NFV (Network Function Virtualization) is a powerful emerging technique with widespread applicability. In this paper, we propose a creative solution to decouple the strong coupling relationship between VNF (Virtualized Network Function) and VNFM (Virtualized Network Function Manager) in the current NFV practice. Our solution is to design a VNFC (Virtualized Network Function Controller). It can quickly automate the deployment of VNF into the Docker container and can use the improved compression algorithm to achieve fast inter-node migration of VNF. We have experimentally proved that Docker\'s performance can be improved by 3 to 4 times compared with VM and the improved compression algorithm can effectively improve the compression ratio.

一种非耦合轻量级的虚拟网络功能控制器
摘要:网络功能虚拟化是一种功能强大的新兴技术,它具有广泛的适用性。在本文中,我们提出了一种创新性的方案来解耦当前的NFV实践中虚拟网络功能和虚拟网络功能管理器之间的强耦合关系。我们的解决方案是设计一个虚拟网络功能集群内控制器,它可以快速的将虚拟网络功能部署到Docker容器中,并可以使用改进的压缩算法实现虚拟网络功能的节点间快速迁移。我们通过实验证明了,与虚拟机相比,Docker的性能可以提高3到4倍,另外改进的压缩算法可以有效地提高压缩率。
