Network Working Group 21 August 1971 Request for Comments 214 E. Harslem-Rand NIC 7195 Category: F Obsoletes: 193, 198


As of August 21 we had performed the following verifications with the sites listed below. These verifications were done on an arranged basis and do not indicate any degree of continuous availability.

In the category "NCP-107" the heading is somewhat misleading. It does not indicate a thorough checkout of all the NCP functions described in Document 1 and RFC-107. It only indicates that the NCP in question functioned to the extent required to respond to a RESET (a necessary condition for the Rand NCP to consider the remote host "up") and that the NCP performed the functions necessary for an ICP. Thus, this column really indicates only a small degree of NCP completeness. Such function as ECHO, Give Back, error message generation and so on were not checked. We have checked some of these functions with UCSB and SDC but not exhaustively. This is mainly due to the tedium of such a process. BBN is currently writing a protocol certifier for their DDP-516 host that will do this automatically.
