　　November, 1974, Survey of New-Protocol TELNETServers

　　Two months have elapsed since our last survey, and the appearance of　additional New-Protocol servers has progressed at the usual snail's　pace. The changes in this list are (with host numbers in octal):

　　SRI-AI (102) now has a New-Protocol server;

　　SDC-LAB (10) is back on the net and the list;

　　SDC-CC (110) is coming on the net but status is as yet unknown;

　　USC-ISI (126) and USC-ISIB (226) (formerly ISI-DEVTENEX) now have　New-Protocol servers;

　　SDAC-44 (32) has been removed -- no longer classed as a server host;

　　HAWAII-500 (344) is coming on the net, status presently unknown;

　　LONDON (52) has been added;

　　BBN-TENEXD is now host 162 (formerly 205).

　　What follows is an update of the summary and tabulation that appeared　in RFC#702.* Is there light at the end of the tunnel?

　　total server hosts 37 100%

　　no New-Prot server 19 51%

　　unknown status (new host) 2 6%

　　total New-Prot implem. 16 43%

　　New-Prot on socket 27,

　　Old on socket 1 (2) 9 24%

　　New-Prot on 1 and 27 (3) 6 16%

　　New-Prot on 1 only (3) 1 3%

　　Notes:

　　* All data in this report were gathered via a surveying program run　at various times, plus a few manual checks to fill out the data.

　　What is reported here is the way the various servers work as seen　by the new-Protocol User Telnet at BBNA, as of 4 Dec. 1974.

　　(2) These are the sites whose operation is 100% correct according to　all protocols and conventions, as I understand them.

　　(3) We realize that some of the servers that appear here as New-Protocol servers on socket 1 are actually servers which attempt　to communicate with both Old- and New-Protocol User TELNETs　according to what control sequences are received.
