Distributed and trustable SDN-NFV-enabled network emulation on testbeds and cloud infrastructures

Giuseppe Di Lena 1, 2, 3, 4, 5
Abstract : In recent years, there have been multiple enhancements in virtualization technologies, cloud computing, and network programmability. The emergence of concepts like Software Defined Networking (SDN) and Network Function Virtualization (NFV) are changing the way the Internet Service Providers manage their services. In parallel, the last decade witnessed the rise of secure public cloud platforms like Amazon AWS and Microsoft Azure. These new concepts lead to cost reductions and fast innovation, driving the adoption of these paradigms by the industry. All these changes also bring new challenges. Networks have become huge and complex while providing different kinds of services. Testing them is increasingly complicated and resource-intensive. To tackle this issues, we propose a new tool that combines emulation technologies and optimization techniques to distribute SDN/NFV experiments in private test-beds and public cloud platforms. Cloud providers, in general, deliver specific metrics to the users in terms of CPU and memory resources for the services they propose, but they tend to give a high-level overview for the network delay, without any specific value. This is a problem when deploying a delay-sensitive application in the cloud, since the users do not have any precise data about the delay. We propose a testing framework to monitor the network delay between multiple datacenters in the cloud infrastructures. Finally, in the context of SDN/NFV networks, we exploit the SDN centralized logic to implement an optimal routing strategy in case of multiple link failures in the network. We also created a test-bed environment to validate our proposition in different network topologies.
