Poster : Loading Programmable Data Plane Programs to Virtual Plane

Virtualization of the programmable data plane allows multiple virtual pipelines to be placed on the same physical programmable device, enabling more flexible network function composition, debugging, etc. Existing proposals realize virtualization with a hypervisor-like program to emulate users’ programs, which becomes the mainstream of the current methods. In spite of the progress achieved, their designs lack study of how to load other programs on this hypervisor. In this poster, we present HyperC, the first compiler for virtualization in programmable data plane, which helps to build a complete virtualization system. HyperC specially optimizes its IR, which makes the hypervisor acquire a decreasing delay by 26.3% on average. At the same time, we solve the placement problem of different users under the restriction of virtual plane resources.
