For the case where the packet has to wait at the source before it can be forwarded, D' n is zero with probability one before the first forwarding phase (n = 0).
If it would be more convenient just sign the bill and it can be forwarded at the regular date for payment.
Mr. Ritea said that both drivers involved in an accident would receive a bill, but that it would "indicate it can be forwarded to responsible party and their insurer," which he said would pay the city.

Label switching relies on associating a small, fixed-format label with each data packet so that it can be forwarded in the network.
The forwarding phase is used to characterize how much closer a packet gets to the destination when it can be forwarded within a connected partition of the network.
Once forwarding is not possible, the waiting phase accounts for how long time a packet has to wait until it can be forwarded again.
It writes like a normal ballpoint pen, but is enhanced with electronics that can record what you write; then send it to a Bluetooth-enabled PC or mobile phone, from which it can be forwarded in an e-mail.
The file can be listened to up to five times on any one computer – meaning it can be forwarded to others and they can listen to it five times, too.
The two cases in the figure illustrate that when a packet is generated by the source, it either has to wait if the source node is at the frontier of a partition (upper track) or it can be forwarded immediately, within the current partition, until it reaches the edge (lower track).
