Happy 40th, Internet

The Internet is 40 years old today.

The very first host-to-host packet-switched message ever sent over the fledgling "ARPANET", an information network developed by BBN Technologies under a contract awarded by the Pentagon's "Advanced Research Projects Agency" (today known as DARPA), was sent 40 years ago today.

At 10:30pm PDT on October 29th, 1969, a UCLA student using an SDS "Sigma 7" host computer sent the word "login" to an SDS 940 interface message processor (IMP) 300 miles north at the Stanfurd Research Institute. Though the system crashed after only the first two letters were transmitted ("lo"), the remote IMP login was accomplished an hour later.

The original 1822 protocol, which was designed for reliability and assurance (i.e., the host would be able to tell if a message was lost), was later replaced with the Network Control Program (NCP) that allowed simultaneous message sharing between different hosts. The modern Transfer Control Protocol / Internet Protocol (TCP/IP) was adopted by ARPANET in 1983.

ARPA, the world's 200 million plus blogs thank you.
