1. A system comprising:
a plurality of physical machines, each physical machine executing a virtual machine that runs a Virtual Network Function (VNF) component of a VNF, each physical machine comprising:
a first physical network interface; and
a second physical network interface;
wherein each VNF component uses a first virtual network interface and the first physical network interface of its respective physical machine to communicate with a first network and uses a second virtual network interface and the second physical network interface of its respective physical machine to communicate with a second network isolated from the first network, wherein the VNF component acts as a demarcation point between the first and second networks such that traffic for the first network is not shared on any network cable with traffic for the second network.
