   * C: Congestion notification. If a node drops a CTP data frame, it MUST set the C field on the next data frame it transmits.
   * THL: Time Has Lived. When a node generates a CTP data frame, it MUST set THL to 0. When a node receives a CTP data frame, it MUST increment the THL. If a node receives a THL of 255, it increments it to 0.
   * ETX: The ETX routing metric of the single-hop sender. When a node transmits a CTP data frame, it MUST put the ETX value of its route through the single-hop destination in the ETX field.  If a node receives a packet with a lower gradient than its own, then it MUST schedule a routing frame in the near future.

-  * P: Same as data frame with one difference: Routing frames are broadcast so multiple nodes respond to the P bit in the routing frame. Thus, the P bit in the routing frame can be used for quick bootstrapping of the routes: when a node boots up and sends a frame with the P bit set, the neighboring nodes can quickly transmit routing frames advertising their routes enabling the new node to quickly compute the route to the sink.

 significantly, then CTP SHOULD transmit a broadcast frame soon thereafter
