“…In this section, we verify and evaluate the routing emulation technology of this paper. First, we verify the routing and forwarding function of routing nodes and OSPF function through experiments in Section 6.2. en, we compare the routing emulation technology in this paper (named as highperformance technology), in [33,34] (named as virtualization technology), and in [19] (named as high-throughput technology). Section 6.3 compares the cost of the three routing emulation technologies, and Section 6.4 compares the performance.…”

“…Routing emulation software provides essential support for the routing emulation solutions based on cloud computing and virtualization technology. In [33], Quagga is deployed on a virtual machine, providing various routing function emulations. Huang et al [34] use Linux Containers (LXC) [35] to provide a running environment for virtual routers and use the Xtensible Open Router Platform (XORP) or Click to build a routing node.…”

“…Huang et al [34] use Linux Containers (LXC) [35] to provide a running environment for virtual routers and use the Xtensible Open Router Platform (XORP) or Click to build a routing node. However, the routing emulation solutions in [33,34] build routing nodes by deploying routing emulation software on virtual machines, which leads to defects in overhead and performance of routing nodes in the routing emulation network.…”

Currently, the emergence of edge computing provides low-latency and high-efficiency computing for the Internet of Things (IoT). However, new architectures, protocols, and security technologies of edge computing need to be verified and evaluated before use. Since network emulation based on a cloud platform has advantages in scalability and fidelity, it can provide an effective network environment for verifying and evaluating new edge computing technologies. Therefore, we propose a high-performance emulation technology supporting the routing protocol based on a cloud platform. First, we take OpenStack as a basic network environment. To improve the performance and scalability of routing emulation, we then design the routing emulation architecture according to the software-defined network (SDN) and design the cluster scheduling mechanism. Finally, the design of the Open Shortest Path First (OSPF) protocol can support communication with physical routers. Through extensive experiments, we demonstrate that this technology not only can provide a realistic OSPF protocol but also has obvious advantages in the overhead and performance of routing nodes compared with those of other network emulation technologies. Furthermore, the realization of the controller cluster improves the scalability in the emulation scale.
