Defining Internet– three layers
1. The physical layer (the network's hardware and wires)
2. the logical layer (the protocols that determine who connects to what)
3. the content layer (the actual material delivered by the protocols over the wires

A set of standards for interconnecting networks A network of networks

Internet Timeline (cont)
1972 ARPANET demonstrated (operational by 1975)1974 TCP (TCP/IP by 1978) Vint Cerf & Bob Kahn
Enables packet switching IP – packets, TCP – connections
1983 ARPANET separates into MILNET and ARPA-INTERNET Domain Name System .edu, .gov, .com, .mil, .org, .net, .int
1984 NSF expands high speed network1990 ARPANET decommissioned, net privatized
ISPs create networks based on ARPANET’s design 1000s of ISPs cooperate with one another to create the Internet

Principles of Internet Architecture:
distributed (no central control)end to end principle “stupid network”
Passing of packets are neutral (though some ISPs filter
open communication protocols (language)multilayered (layers isolated)compatibility between networks
“An open system of computer communication” –Castells

documented and developed
key Internet standardsTCP/IP – basic Net protocolsSMTP – email transferDNS – name servers
ran the Internet naming & address system on a voluntary, free-of-charge, and public
interest basis

At 5:04pm on Jan 28th 1998 Jon Postel pulls the root!
attempt to wrestle root control away from US Gov. and Network Solutions
Jan 29th US secures
root authorityOctober 16th 1998
Jon Postel dies (some say
from stress over DNS root
authority)
