Internet Timeline first electronic mail on a single computer first book on packet switching theory ARPA funds ARPA Computer Network (ARPANET) first ARPANET node at UCLA Oct first network connection between two computers on ARPANET first networked electronic mail

ARPA changes name to DARPA development of Ethernet; initial development of TCP/IP experimental Internet first use of :-) in (used to express emotion) operational Internet; development of PCs and workstations NSF funds 5 national supercomputer centers; NSF and DARPA agree to mutual access

NSFNET backbone = 56 Kb/sec; NSFNET regionals develop; creation of IETF and IRTF fiber optics become cost effective NSFNET backbone = 1.5 Mb/sec NSFNET Acceptable Use Policy prohibits backbone usage for purposes “not in support of Research and Education” ARPANET retired NSFNET backbone = 45 Mb/sec

new commercial backbones emerge: Alternet, PSINet, ANS (MCI); NSFNET traffic = 1 trillion bytes/month new concept developed: World Wide Web; number of computers on Internet = 1,000, PSINet and AlterNet backbones = 45 Mb/sec; DARPA changes name to ARPA

Sprint begins selling Internet connectivity; WWW traffic across NFSNET increases 1600 times; NSFNET traffic exceeds 10 trillion bytes per month; can now order Pizza Hut on the Web MCI begins selling Internet connectivity; NSF’s funding on all this from = $200 million Federal Networking Council resolution “defines” Internet (not invented by Al Gore!)

FNC Defines Internet RESOLUTION: The Federal Networking Council agrees that the following languages reflects our definition of the term “Internet”. “Internet” refers to the global information system that - (i) is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons; (ii) is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols; and (iii) provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein.

NSFNET reverts back to a research network; existing sites have to use commercial network providers NSF creates new research network: vBNS, linking supercomputer centers ARPA changes name to DARPA; MCI backbone = 622 Mb/sec Nov Internet 2 project begins MCI (vBNS provider for NSF) upgrades backbone to 2.5 Gb/sec
