Network Working Group Ellen Westheimer Request for Comments: 367 BBN NIC #11014 19 July 1972 Category: F, G.3 Updates: 366 Obsoletes: None

                        NETWORK HOST STATUS
 This RFC reports on the status of most Network Hosts from July 3 to
 July 14.
 No testing was done on July 4 as BBN took a holiday to celebrate
 Independence Day.  No testing was done on July 11 and 12 as I was on
 vacation.
 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.
  1. ——–
  • 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.

 where

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.
