NFD

Test correctness of unicast faces.

Build three virtual machines connected via IP network as A-R-B.

Host A and B are NDN nodes.

Host R is an IP router, and is not a NDN forwarder. This is required in the topology to avoid host A and B communicate over multicast.

1. Script is invoked on host A. Command line arguments:
   • SSH hostname for host B.
   • FaceUri of host B's forwarder, which could be tcp4, tcp6, udp4, udp6.
2. Start NFD on A and B.
   • Script should control host B via ssh.
3. On host A, invoke nfdc to initiate a tunnel to B using the given FaceUri.
4. On host A, invoke nfdc to add a nexthop record to the tunnel, so that Interests under a certain prefix go to B. The prefix can be hard coded.
5. Run traffic generator producer on host B, and run traffic generator consumer on host A.
6. Collect results.

The script can assume:

• All programs involved are installed and accessible in $PATH.
• IP router R is correctly configured and can forward IP packets between A and B.
• Executing ssh <SSH hostname for host B> on host A gives a terminal of host B with sudo privilege.
• The integrated tests repository is cloned at the same path on host A and B, and has the same version.
