Telnet TN3270 Enhancements (tn3270e) ------------------------------------ Charter Last Modified: 2003-03-25 Current Status: Active Working Group Chair(s): Michael Boe Applications Area Director(s): Ned Freed Ted Hardie Applications Area Advisor: Ned Freed Technical Advisor(s): Robert Moskowitz Mailing Lists: General Discussion:tn3270e@list.nih.gov To Subscribe: listserv@list.nih.gov In Body: sub tn3270e Archive: listserv@list.nih.gov Description of Working Group: Present specifications for access to 3270 and 5250 based applications over TCP/IP require improvement to become more commercially viable. Security, Service Location, Response Time, and Session Balancing are improvement examples. The WG will drive to update and extend the standards specifications proposed in rfc1647 and rfc1205 so that they fully support 3270 and 5250 style access to host (S/390 and AS/400) applications respectively in today's environments. Consideration will be given to work already in progress on protocols for accessing 3270 and 5250 based applications over TCP/IP. Three protocol documents will be produced. Deliverables 1. A revised version of rfc1647 (tn3270e) including clarifications of the protocol, and security considerations. The revised rfc1647 will be submitted to the IESG for advancement of the tn3270e protocol to draft standard status. Currently it is a proposed standard. 2. A new standards track document defining options for the tn3270e protocol. Such options are: IPDS printing, response time monitoring, error reporting, session balancing, service location, and security. 3. A new standards track document defining enhancements to the tn5250 protocol. This new protocol will be called tn5250e. This is not Display Station Passthru but printing, LU assignment, service location, and security. Goals and Milestones: Done Propose a list of initial TN5250e enhancements on listsrv for review. Done Discuss scope of initial tn5250ec enhancements at IETF session. Done Goal 1 revised tn3270e (rfc1647) Conduct interoperability testing.
