The IESG has approved publication of the following Internet-Drafts as Proposed Standards: o The Multi-Class Extension to Multi-Link PPP <draft-ietf-issll-isslow-mcml-06.txt> o PPP in a real-time oriented HDLC-like framing <draft-ietf-issll-isslow-rtf-05.txt> o Integrated Services Mappings for Low Speed Networks <draft-ietf-issll-isslow-svcmap-08.txt> In the same action, the IESG also approved publication of Providing integrated services over low-bitrate links <draft-ietf-issll-isslow-06.txt> as an Informational RFC. These documents are the product of the Integrated Services over Specific Link Layers Working Group. The IESG contact persons are Scott Bradner and Vern Paxson. Technical Summary These documents describe an architecture and technology for providing integrated services over low-bitrate links, such as modem lines, ISDN B-channels, and sub-T1 links. The main components of the architecture are: a real-time encapsulation format for asynchronous and synchronous low-bitrate links, a header compression architecture optimized for real-time flows, elements of negotiation protocols used between routers (or between hosts and routers), and announcement protocols used by applications to allow this negotiation to take place. The Multi-Class Extension to Multi-Link PPP document describes a fragment-oriented solution for the real-time encapsulation format part of the architecture. The general approach is to start from the PPP Multilink fragmentation protocol and provide a small number of extensions to add functionality and reduce the overhead. The PPP in a real-time oriented HDLC-like framing document describes a suspend/resume-oriented solution for the real-time encapsulation format part of the architecture. The general approach is to start from the PPP Multilink fragmentation protocol and its multi-class extension and add suspend/resume in a way that is as compatible to existing hard- and firmware as possible. The Integrated Services Mappings for Low Speed Networks document defines the service mappings of the IETF Integrated Services for low-bitrate links, specifically the controlled load [5] and guaranteed [6] services. The approach takes the form of a set of guidelines and considerations for implementing these services, along with evaluation criteria for elements providing these services. Working Group Summary The working group supported these documents and no issues were raised during IETF Last-Call Protocol Quality ' These documents were reviewed for the IESG by Scott Bradner.
