    22Sandbox 9 uses the !OpenFlow capable switch as part of its setup as a means to provide a testbed for experimentation with the !OpenFlow protocol. This tutorial
    33covers the following:
    4  * The network topology of the testbed
     4 * The network topology of the SB9
    55 * Installation of the !OpenFlow Reference System and NOX
    66 * Operating the controller
    77 * Performance analysis tools

    10 === !OpenFlow Protocol ===
    11 !OpenFlow is a protocol that allows for the creation of overlay networks over pre-existing network infrastructure. This allows a researcher to run experiments on production networks without the fear of affecting any of the legacy installations or setups, while having control over how data is handled across the network.

    14 "!OpenFlow Protocol" specifically refers to the protocol that is used by a network device and its controller to pass information about flows, or instructions on how to handle data packets based on the packet header, to each other.
