报告摘要:

As cloud computing becomes ubiquitous, the network stack in this virtualized environment is becoming a focal point of research with unique challenges and opportunities. In this talk, I will introduce our efforts in this space. First, from an architectural perspective, the network stack remains a part of the guest OS inside a VM in the cloud. I will argue that this legacy architecture is becoming a barrier to innovation/evolution. The tight coupling between the networkstackand the guest OS causes many deployment troubles to tenants and management and efficiency problems to the cloud provider. I will present our vision of providing the network stack as a service as a way to address these issues. The idea is to decouple the network stack from the guest OS, and offer it as an independent entity implemented by the cloud provider. I will discuss the design and evaluation of a concrete framework called NetKernel to enable this vision. Then in the second part, I will focus on container communication, which is a common scenario in the cloud. I will present a new system called PipeDevice that adopts a hardware-software co-design approach to enable low-overhead intra-host container communication using commodity FPGA.
