A new Request for Comments is now available in online RFC libraries. RFC 1680: Title: IPng Support for ATM Services Author: C. Brazdziunas Mailbox: crb@faline.bellcore.com Pages: 7 Characters: 17,846 Updates/Obsoletes: none This document was submitted to the IETF IPng area in response to RFC 1550. Publication of this document does not imply acceptance by the IPng area of any ideas expressed within. Comments should be submitted to the big-internet@munnari.oz.au mailing list. This white paper describes engineering considerations for IPng as solicited by RFC 1550. IPng should provide support for existing and emerging link technologies that it will be transported over. Link technologies like Ethernet simply multiplex traffic from upper layer protocols onto a single channel. "Sophisticated" link technologies like ATM are emerging in the marketplace allowing several virtual channels to be established over a single wire (or fiber) potentially based on an applications' network performance objectives.
