Summary:Virtual links are important building blocks which connect virtual hosts to form virtual networking within a physical host, and thus their link types can potentially impact the performance of virtual networking. This article studies such a performance impact due to the adopted virtual link type, defined by the associated virtual ports at both ends of the link. Two virtual link types have been investigated, including the native virtual ethernet ports (i.e., veth-pair links) for Linux network namespaces and bridging, and Open vSwitch-based internal ports (i.e., internal links). Several design principles are proposed based on our performance benchmarking results, which show substantial performance gaps among these two virtual link types, particularly for a large number of traffic connections, where the CPU capability could play an important role to the amplified level of performance gaps. Further outlooks into the convergence of Cloud/SDN/NFV and 5G networking are projected, where virtual networking plays an important role.
