The Internet -- The Design Philosophy
The network is assumed to be unreliable
- Communications always occurs between a source and destination computer
- Minimum of information about clients needed: data is put in an envelope called Internet Protocol (IP) packet and this packet is addressed
- Communicating computers (nodes) are responsible for successful communications not the network.
The principal: Any computer can talk to any other computer in the network as a peer (peer-to-peer network).
