Abstract

See full text

Some embodiments of the invention provide a robust scaling-out of network functionality by providing a software layer, called the network hypervisor, that sits between the network forwarding functions (i.e., the forwarding plane) and the network control interfaces (i.e., the control plane). The network hypervisor of some embodiments provides a logical abstraction of the network's forwarding functionality, so that network operators make their control decisions in terms of this abstraction, independent of the details of the underlying networking hardware. The network hypervisor of some embodiments may then “compile” commands placed against this abstraction into configurations of the underlying hardware. Accordingly, in some embodiments, there are two design challenges: (1) the choice of the network abstraction, and (2) the technology needed to compile the logical “abstract” controls into low-level configurations.
