SUMMARY:Hop Recording and Forwarding State Logging: Two Implementations fo
 r Path Tracking in P4
DESCRIPTION:Workshop\n\nHop Recording and Forwarding State Logging: Two Im
 plementations for Path Tracking in P4\n\nKnossen, Hill, Grosso\n\nFull inf
 ormation on the path travelled by packets is extremely important for netwo
 rk management and network security. We implemented two path tracking metho
 ds in hardware with P4. The first approach  tracks a packet’s path by reco
 rding each node along the path of a packet (hop recording). The complete p
 ath a packet took can be extracted from the packet in the last node of the
  path. The second approach tracks a packet’s path by logging the forwardin
 g state of a network (forwarding state logging).  The complete path can be
  reconstructed based on the node where the packet entered a network. We co
 nducted experiments with the two implemented approaches and showed that th
 e paths of the packets are reconstructed correctly. The advantage of using
  P4 is that the control plane only gets involved when the path of a packet
  is reconstructed. We finally show how our work provides a working tool in
  P4 networks that can be used to gain deep insights in traffic patterns.\n
