ENCAPSULATION ACROSS MULTIPLE HOPS:

 Each router in the path from the source to the receiver unencapsulates incoming datagram from frame message, processes datagram and calculates next hop  and encapsulates datagram in outgoing message frame. Datagram can be encapsulated in different hardware format at every hop. Datagram itself is unmodified as given in the figure below.
