Software-Based Networks: Leveraging high-performance NFV platforms to meet future communication challenges


Communication networks are changing. They are becoming more and more “software-based.” The use of Network Function Virtualization (NFV) to run network services in software, along with the concept of Software Defined Networks (SDN), will lead to a largely software-based network environment. To truly achieve the vision of a high-performance software-based network that is flexible, lower- cost, and agile, a fast and carefully designed NFV platform along with a comprehensive SDN control plane is needed. Our high-performance NFV platform, OpenNetVM, enables high bandwidth network functions to operate at near line speed, while taking advantage of the flexibility and customization of low cost commodity servers. We envision a dynamic and flexible network that can support a smarter data plane than just simple switches that forward packets. Use of OpenNetVM opens up opportunities to re-architect the way networks are put together. As an example, we demonstrate the utility of OpenNetVM for supporting future cellular networks (e.g., 5G and beyond). NFV enables dynamic management of capacity to support the Mobile Core Network of future cellular networks. Truly exploiting the opportunities of a software-based environment requires careful thinking about the protocols utilized as well. We describe CleanG, a simplified software-based architecture for the cellular core network with a simplified control plane protocol. CleanG offers substantial performance benefits over current approaches.
