论文摘要
我们重新访问数据中心中的多租户虚拟化虚拟化，并为特定于租户的虚拟开关提供案例。特别是，特定于租户的虚拟开关允许云提供商可以将细粒度的计费（例如，从无服务器架构）扩展到网络，不仅对IO进行了核算，还可以核算CPU或能源。我们绘制建筑，目前的经济动机和最新的技术推动力。我们还发现，当今虚拟开关没有提供足够的多租户，并且可以在负载平衡器中引入人造性能瓶颈。我们通过讨论针对特定特定开关的其他用例来结束。
We revisit multi-tenant network virtualization in data centers, and make the case for tenant-specific virtual switches. In particular, tenant-specific virtual switches allow cloud providers to extend fine-grained billing (known, e.g., from serverless architectures) to the network, accounting not only for IO, but also CPU or energy. We sketch an architecture and present economical motivation and recent technological enablers. We also find that virtual switches today do not offer sufficient multi-tenancy and can introduce artificial performance bottlenecks, e.g., in load balancers. We conclude by discussing additional use cases for tentant-specific switches.
