1. A method of providing network communications using virtualization, comprising the steps of:

  • (a) detecting, at a first device, a request for a network connection from an application running on the first device;

    (b) spawning, at the first device, a first virtual machine that virtualizes network capabilities of the first device such that a first virtual network connection is provided to the application, the application running external to the first virtual machine;

    (c) selecting, at the first device, a first routing protocol for the first virtual network connection from among a plurality of available routing protocols for communicating data using the first virtual network connection;

    (d) detecting, at the first device, another request for a network connection from the application running on the first device;

    (e) spawning, at the first device, a second virtual machine that virtualizes network capabilities of the first device such that a second virtual network connection is provided to the application, the application running external to the second virtual machine;

    (f) selecting, at the first device, a second routing protocol for the second network connection from among the plurality of available routing protocols for communicating data using the second virtual network connection;

    (g) using the selected first routing protocol of said step (c), communicating data from the application in a plurality of packets to a destination device, the method involving, for each packet,(i) transmitting, from the first device using the first virtual network connection and the selected first routing protocol, the packet for communication to the destination device,(ii) receiving, at a third virtual machine that runs on a second device and that virtualizes network capabilities of the second device such that a third virtual network connection is provided, the packet,(iii) transmitting, from the second device using the third virtual network connection and the selected first routing protocol, the packet for communication to the destination device, and(iv) receiving, at a fourth virtual machine that runs on the destination device and that virtualizes network capabilities of the destination device, the packet; and

    (h) using the selected second routing protocol of said step (f), communicating data from the application in a plurality of packets to a destination device, the method involving, for each packet,(i) transmitting, from the first device using the second virtual network connection and the selected second routing protocol, the packet for communication to the destination device,(ii) receiving, at a fifth virtual machine that runs on a third device and that virtualizes network capabilities of the third device such that a fifth virtual network connection is provided, the packet,(iii) transmitting, from the third device using the fifth virtual network connection and the selected second routing protocol, the packet for communication to the destination device, and(iv) receiving, at a sixth virtual machine that runs on the destination device and that virtualizes network capabilities of the destination device, the packet;

    (i) wherein the selected first routing protocol of step (c) is different from the selected second routing protocol of step (f).
