    3 In this section we will use a different type of !ChoiceNet service to route and forward packets across the slice.  In particular, we will use an SDN-based (i.e., OpenFlow-based) !ChoiceNet service to forward packets.  During the [wiki:GEC21Agenda/ChoiceNet/gt_tool Configure and Install !ChoiceNet Software] step we already downloaded and configured the software needed for this section, consequently the next step is to run applications that will make use of this new SDN-based service.

    9 The SDN-based implementation has an SDN controller that knows the network topology and detect the path services. It also has a marketplace server which accepts the service advertisement from controller and handles the user request.

    11 Although the controller and marketplace are services offered by providers and conceptually should be run on provider machines, for purposes of this tutorial they are located on H1 (to reduce the number of VMs in the slice).

    28 Open up two ssh session terminals to the H2 Node ( we can call them '''TERMINAL 2''' and '''TERMINAL 3''' ). First run the !ChoiceNet App on '''TERMINAL 2'''. The !ChoiceNet App will communicate with marketplace to request for path service and deal with payment.

    42 After login, the app will intercept any TCP SYN packets with destination IP 10.0.0.0/8 and destination port 8080 or 443. Once it intercepts a packet, it communicates with the marketplace and requests for a path service with 3-minute duration. This means it is compatible with almost any existing network applications, here we will use wget and mplayer as two examples.
