NETWORK HOST STATUS
This RFC reports on the status of most Network Hosts from June 19
to June 30.
No testing was done on June 20 due to an attempt to install the
new IMP system.
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.)
_______________
*The only service currently offered by the UCLA IBM-360/91 is a Network
Job Service (NETRJS), however, the BBN Terminal IMP is not equipped to
test NETRJS. We are assuming that initial connection to the NETRJS
logger indicates that NETRJS is also functioning.
#These sites advertise that they may not have their system available
at these times.
