UGUST, 1974, SURVEY OF NEW-PROTOCOL TELNET SERVERS

THIS IS THE FIRST OF WHAT ARE PLANNED TO BE MONTHLY REPORTS ON THE STATUS OF THE NEW-PROTOCOL TELNET IMPLEMENTAIONS ON THE SERVER HOSTS ON THE ARPA NETWORK. INCLUDED IN THIS REPORT ARE DATA ONLY ON SERVER TELNETS AT THE VARIOUS SITES. ONE WOULD HOPE THAT ANY SITE WITH AN OPERATIONAL NEW-PROTOCOL SERVER TELNET WOULD ALSO BOAST A NEW-PROTOCOL USER TELNET; WE CAN CERTAINLY ASSUME THIS FOR TENEX SITES AT WHICH TENEX 1.32 IS OPERATING. HOWEVER, NO FURTHER CLAIMS ARE MADE FOR THE SERVER DATA CONTAINED IN THIS REPORT.

I AM SORRY TO REPORT THAT AT THIS LATE DATE, A MONTH AFTER THE RELEASE OF TENEX 1.32, LESS THAN ONE-THIRD OF THE SERVER SITES HAVE ANY NEW- PROTOCOL SERVER OPERATING, ACCORDING TO MY SURVEYS*, AND ONLY HALF OF THOSE ARE USING CORRECTLY THE LOGGER SOCKET CONVENTIONS, AS I UNDERSTAND THEM. AT THE END OF THIS REPORT IS A COMPLETE TABULATION COMPILED FROM MY SURVEYS; THE FOLLOWING IS A SUMMARY:

        OTAL SERVER HOSTS       32      00%
        
        TATUS UNKNOWN (1)        3       9%
        
        O NEW-PROT SERVER       19      59%
        
        OTAL NEW-PROT IMPLEM.   10      31%
        
         NEW-PROT ON SOCKET 27,
         OLD ON SOCKET 1 (2)     5      16%
        
         NEW-PROT ON 1 AND 27 (3)       4       13%
        
         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 15 AUG. 1974. THERE MAY BE DISCREPANCIES BETWEEN THESE RESULTS AND THOSE FROM SURVEYS MADE AT OTHER SITES.

(1) NUMEROUS ATTEMPTS TO CONNECT TO THESE SITES ALL FAILED DUE TO

THE SITES' BEING DOWN TO THE NETWORK.

(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.
