Title: SINGLE NETWORK INTERFACE FOR MULTIPLE INTERFACE VIRTUAL NETWORK FUNCTIONS
Abstract:
A virtual network function includes network interface via a single client network interface coupled to a network functions infrastructure. The network interface is provided using a virtual network function abstraction layer in the form of an implementation of a virtual network function in a virtual machine nested within a second virtual machine having a virtual switch. Routing between any number of ports on the virtual network function and a single network interface is enabled by providing a virtual interface in the switch mapped to each network interface needed by the virtual network function. Data from a client network via the network interface for the infrastructure is routed to the proper virtual network function interface in the virtual switch.
