The network transition to exclusive use of TCP/IP took place as scheduled. The net is up with relatively few NCP-only exemptions granted. Individual host TCP implementation problems have occurred and exemptions were granted to those sites experiencing severe disruption of service. The exemptions are temporary and firm cutover dates (to TCP-only operation) have been published (see Table 1). 2. To support those users whose hosts are still using NCP, the ARPANET terminal access controllers (TAC) will continue to support NCP through January 1983. This will allow hosts using NCP an opportunity to transition to TCP without seriously disrupting remote terminal service. Terminal users will have to enter an additional command when connecting to a TAC in order to communicate with NCP hosts. As of 1 Feb 83, all TACs will run TCP/IP only. 3. The University of Delaware (UDEL) has agreed to serve as a mail- forwarding relay during the transition period. A modification to normal addressing is necessary as described below: a. A TCP user with mail for an NCP user will address TO: .@UDEL-RELAY. Example: PVAYDA.OFFICE-10@UDEL-RELAY. Important: The origin host must be TCP. b. An NCP user with mail for a TCP user will address TO: .@UDEL-TCP. Example: DHENRY.BBNC@UDEL-TCP. Important: The origin host must be NCP. c. UDEL will return incorrectly addressed messages. Should the destination host protocol not be known, or be transitioning, UDEL will complete the transaction (TCP to TCP, or NCP to NCP). The critical point is the correct protocol of the sender. d. POC at UDEL is Mr. Brendan Reilly, (302) 738-1266, Reilly@UDEL-RELAY. 4. The list of TCP exemptions is included for your information (Table 1) to enable effective use of the UDEL relay. 5. Should unforeseen problems result in a need to request NCP enablement, Newsletter No. 19 establishes reclama procedures. Briefly, reclamas should provide your justification, schedule for TCP-only implementation, source of TCP conversion effort, and a list of the hosts you communicate with. TCP exemptions are granted on an individual host basis and each host administrator must individually request NCP enablement. POC for all such requests is Major Bruce Sweeny, DCACODEB627@BBN-TENEXB, or by phone, (703) 285-5020. 6. Thank you for your patience and cooperation. ----- Table 1.
