Proposed User-User Protocol
George H. Mealy · 1970
There are many good reasons, and maybe one or two bad ones, for making it appear that communication over the Network is only a special case of input/output --at least as far as user programming is concerned.Thus, for instance, the Harvard approach toward implementing the HOST-HOST protocol and Network Control Program treats each link as a "logical device" in PDP-10 terminology.Setting up a connection is similar to local device assignment, and communication over a link will make use of the standard system input/output UUO's.This makes it possible to use existing programs in conjunction with the Network without modification --at least if other PDP-10's are being dealt with.
