History of the Internet
IMP
In early 1967 Bob Taylor called with members the
possible host sited for the networks and staff members at IPTO and ARPA at Ann Arbor
Michigan to discuss the network project to come. During the meeting there was allot of
bickering over if there should be a main host for the new network to process and transmit
everything, or not. The problem that they were facing was a protocol for the computers to
communicate to the host, every computer spoke a different language from another. On the
way back to the airport after the meeting, Wes Clark came up with an idea for having small
"hosts" at each computer in the network. Clark explained that with the smaller
hosts, the network would consist of one language making it easier to control. They
realized only Frank Heart could build the hosts who, at the time, was working at BBN but who use to work as a computer
systems engineer at MITs Lincoln
Lab.
By the end of 1967 Larry Roberts wrote his first proposal on the soon
to be "ARPA net" using the hosts, or Interface Message Processor (IMP), and Paul
Barans and Donald Davies idea of Packet switching. Roberts decided UCLA, Stranford
Research Institute (SRI), University of Utah and the University of California would be the
first four institutes to receive the IMPs for the network.

Larry Roberts
On July 1968 Larry Robert sent out a proposal for
building the IMPs to over 140 companies and more that 12 responded.
Jerry Elkind was in charge of both the computer divisions at BBN when
ARPA sent out the request for building the IMPs. Elkind suggested to Heart that he should
gather some of the BBN workers to write out the proposal to ARPA. During the proposal,
they stated that the IMP would be create using Honywell DDP-516s because of its
reliability and multiple function capability. Little did they know that the by the time
they finished writing the proposal on September 6 1968, it would be over 200 pages long at
a cost of over $100,000. The small close knitted group of workers would soon be referred
as the IMP guy for their achievements in creating the first Information Message
Processors.

Just a few days before Christmas, in 1968, the contract for
building the IMPs, was awarded to Bolt
