The IESG has approved the following Internet-Drafts as Proposed Standards: o SBM (Subnet Bandwidth Manager): A Protocol for RSVP-based Admission Control over IEEE 802-style networks <draft-ietf-issll-is802-sbm-10.txt> o Integrated Service Mappings on IEEE 802 Networks <draft-ietf-issll-is802-svc-mapping-04.txt> In the same action, the IESG also approved publication of A Framework for Providing Integrated Services Over Shared and Switched IEEE 802 LAN Technologies <draft-ietf-issll-is802-framework-07.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 define the Subnet Bandwidth Manager (SBM) protocol, a set of service mappings to be used with SBM and a framework for providing Integrated Services over shared and switched IEEE-802-style LAN technologies. The SBM (Subnet Bandwidth Manager) protocol provides a method for mapping an internet-level setup protocol such as RSVP onto IEEE 802-style networks. In particular, it describes the operation of RSVP-enabled hosts/routers and link layer devices (switches, bridges) to support reservation of LAN resources for RSVP-enabled data flows. The service mapping document describes mappings of IETF Integrated Services over LANs built from IEEE 802 network segments which may be interconnected by IEEE 802.1D MAC Bridges (switches). It describes parameter mappings for supporting Controlled Load and Guaranteed Service using the inherent capabilities of relevant IEEE 802 technologies The framework document describes a framework for supporting IETF Integrated Services on shared and switched LAN infrastructure. It includes background material on the capabilities of IEEE 802 like networks with regard to parameters that affect Integrated Services such as access latency, delay variation and queuing support in LAN switches. It discusses aspects of IETF's Integrated Services model that cannot easily be accommodated in different LAN environments. It outlines a functional model for supporting the Resource Reservation Protocol (RSVP) in such LAN environments. Working Group Summary The working group supported the publication of these documents and no issues were raised during IETF Last-Call. Protocol Quality These documents were reviewed for the IESG by Scott Bradner.
