The unbundling of services has led to exponential growth in the size of APIs. With the expansion of network scales, the B/S architecture of monolithic applications is gradually being replaced by microservices. At the same time, the presented results and analysis provide a deeper insight into the design tradeoffs and identifies potential performance bottlenecks that could inspire new designs. It is, therefore, crucial to choose the most suitable solution for the given use case.

Our experimental results show that no single software switch prevails in all scenarios. In our experiments, we evaluate the throughput and latency between VNFs in two of the most popular virtualization environments, namely virtual machines (VMs) and containers. Each scenario corresponds to a specific case of routing NFV traffic between NICs and/or VNFs. We first explore the design spaces of seven state-of-the-art software switches and then compare their performance under four representative test scenarios. In this paper, we propose a methodology to compare fairly and comprehensively the performance of software switches. It is of paramount importance to compare the performance of different switch designs and architectures. Software switches route traffic between VNFs and physical Network Interface Cards (NICs). With the ultimate goal of replacing proprietary hardware appliances with Virtual Network Functions (VNFs) implemented in software, Network Function Virtualization (NFV) has been gaining popularity in the past few years. At the same time, the presented results and analysis provide a more in-depth insight into the design tradeoffs and identify potential performance bottlenecks that could inspire new designs.

We first explore the design spaces of 7 state-of-the-art software switches and then compare their performance under four representative test scenarios. It is thus of paramount importance to compare the performance of different switch designs and architectures. Software switches are widely employed to route traffic between VNFs and physical Network Interface Cards (NICs). With the ultimate goal of replacing proprietary hardware appliances with Virtual Network Functions (VNFs) implemented in software, Network Function Virtualization (NFV) has gained popularity in the past few years. We then compared our work with existing and standard Linux solutions, namely Virtual Ethernet interfaces and Virtual Bridges, finding out that our approach allows efficient simulation of complex networks by means of virtualization techniques, nevertheless achieving both high throughput and low overhead when exchanging packets among nodes. We focus on the interconnection technologies between network nodes, implemented as Linux Containers, by evaluating a recent framework for packet exchange, Netmap, coupled with a Virtual Local Ethernet used as a generic high speed bus, VALE. The former solution suffers in terms of computational overhead and global network's throughput, while the latter can't be employed in actual real-world scenarios. State of the art solutions for network simulation are based on the virtualization of network simulators (so as to emulate network's nodes) or on the usage of specialized software that models the network itself (so as to emulate network's links).
