NETWORK HOST STATUS
This RFC reports on the status of most Network Hosts from July 17
to July 28.
On Tuesday, July 18, the new IMP software was released.
Several Hosts are currently excluded from the daily testing as they are presently intended to be users only. Included here are the Terminal IMPs, which are presently in the Network (AMES, MITRE, RADC, NBS, ETAC, USC, GWC, NOAA, SAAC, ARPA, and BBN*). This category also includes the Network Control Center computer (Network address 5) which is used solely for gathering statistics from the Network. Finally, included among these Hosts are the following: Network Address Site Computer ------- ---- -------- 7 Rand IBM-360/65 73 Harvard PDP-1 138 Lincoln TSP 12 Illinois PDP-11 19 NBS PDP-11 23 USC IBM-360/44
The tables on the next two pages summarize the Host status
for this period.
*The BBN Terminal IMP (Network Address 158) is a prototype and
as such is frequently not connected to the Network, but being
used to refine and debug the Terminal IMP programs.
D = Dead (Destination Host either dead or inaccessible [due to network
partitioning or local IMP failure] from the BBN Terminal IMP.)
F = Full (Destination Host opened a connection, informed user that all
Network ports were in use, and immediately closed the connection.)
H = 1/2 Open (Destination Host opened a connection but then either
immediately closed it, or did not respond any further.)
O = Open (Destination Host opened a connection and was accessible to users.)
R = Refused (Destination Host returned a CLS to the initial RFC.)
T = Timed out (Destination Host did not complete the ICP and open a connection within 60 seconds.) _______________ [ This RFC was put into machine readable form for entry ] [ into the online RFC archives by BBN Corp. under the ] [ direction of Alex McKenzie. 1/97 ]
