TCP/IP Conversion Effective 1 Jan 83
---------------------------------------------------------------------
1. 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: <Account-Name>.<NCP-HostName>@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: <Account-Name>.<TCP-HostName>@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.
