A Protocol for Packet Network Intercommunication
Interconnect heterogeneous packet networks through gateways while end hosts provide process communication, sequencing, retransmission, and flow control.
The central move
Interconnect heterogeneous packet networks through gateways while end hosts provide process communication, sequencing, retransmission, and flow control.
Why it had to exist
Independent packet networks had different packet sizes, timings, and internal rules. A network of networks could not require every participant to replace its local design.
Where it leads
Packet switching → internetworking → TCP/IP → the open Internet application stack.
