The ARPANET was the first packet-based wide-area network; so called because it was initiated, and initially funded, by ARPA.
It consisted of minicomputers called Interface Message Processors ('IMPs', for short) running specialized packet switching code, joined together with synchronous serial lines; host computers were connected to the IMPs by special bit-serial interfaces (see below).
Protocols
The protocol family used on the early ARPANET included:
- The Host-to-IMP Protocol, the bottom layer; specified in BBN Report #1822 (multiple editions over time)
- ICP, Initial connection protocol
- Host-to-Host Protocol (early version here)
These two latter protocols formed the Network Control Program, which all the application protocols ran over.
Those included:
- FTP (early version here)
- TELNET
- MAIL (here is a much later proposal which eventually became SMTP)
- NAME/FINGER
