With the ARPA Network Host-to-Host Protocol specified and at least partially implemented at a number of sites, the question of what steps should be taken next arises. There appears to be a widespread feeling among Network participants that the first step should be the specification and implementation of what has been called the "Logger Protocol"; the Computer Network Group at project MAC agrees. The term "logger" has been commonly used to indicate the basic mechanism to gain access (to "login") to a system from a console. A network logger is intended to specify how the existing logger of a network host is to interface to the network so as to permit a login from a console attached to another host.
