A new Request for Comments is now available from the DDN Network Information Center in the online library at FTP.NISC.SRI.COM. RFC 1240: Title: OSI Connectionless Transport Services on top of UDP - Version: 1 Author: C. Shue, W. Haggerty, & K. Dobbins Mailbox: chi@osf.org, bill@comm.wang.com Pages: 8 Characters: 17,690 Obsoletes/Updates: none pathname: rfc/rfc1240.txt This memo describes a method for offering the OSI connectionless transport service (CLTS) in TCP/IP-based Internets by defining a mapping of the CLTS onto the User Datagram Protocol (UDP). This RFC specifies a Proposed Standard Protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. RFCs can be obtained via FTP from FTP.NISC.SRI.COM, NIS.NSF.NET, or NISC.JVNC.NET. RFCs can be obtained via FTP from FTP.NISC.SRI.COM, with the pathname rfc/rfcNNNN.txt (where "NNNN" refers to the number of the RFC). Login with FTP username "anonymous" and password "guest". SRI also provides an automatic mail service for those sites which cannot use FTP. Address the request to MAIL-SERVER@NISC.SRI.COM and in the body of the message indicate the RFC to be sent: "send rfcNNNN" where NNNN is the RFC number. Multiple requests may be included in the same message. To obtain RFCs from NIS.NSF.NET via FTP, login with username "anonymous" and password "guest"; then connect to the RFC directory ("cd RFC"). The file name is of the form RFCnnnn.TXT-1 (where "nnnn" refers to the number of the RFC). The NIS also provides an automatic mail service for those sites which cannot use FTP. Address the request to NIS-INFO@NIS.NSF.NET and leave the subject field of the message blank. The first line of the text of the message must be "SEND RFCnnnn.TXT-1", where nnnn is replaced by the RFC number. RFCs can also be obtained via FTP from NISC.JVNC.NET, with the pathname rfc/RFCnnnn.TXT.v (where "nnnn" refers to the number of the RFC and "v" refers to the version number of the RFC). JvNCnet also provides a mail service for those sites which cannot use FTP. Address the request to SENDRFC@JVNC.NET and in the subject field of the message indicate the RFC number, as in "Subject: RFCnnnn" where nnnn is the RFC number. Please note that RFCs whose number are less than 1000 need not place a "0". (For example, RFC932 is fine.) No text in the body of the message is needed. Requests for special distribution should be addressed to either the author of the RFC in question, or to NIC@NIC.DDN.MIL. Unless specifically noted otherwise on the RFC itself, all RFCs are for unlimited distribution. Submissions for Requests for Comments should be sent to POSTEL@ISI.EDU. Please consult RFC 1111, "Instructions to RFC Authors", for further information. Requests to be added to or deleted from this distribution list should be sent to RFC-REQUEST@NIC.DDN.MIL. Joyce K.
