The IESG has approved the Internet-Draft 'Integrated Services in the Presence of Compressible Flows' <draft-ietf-intserv-compress-02.txt> as a Proposed Standard. This document is the product of the Integrated Services Working Group. The IESG contact persons are Allison Mankin and Scott Bradner. Technical Summary An Integrated Services router performs admission control and resource allocation based, among other things, on the information contained in a TSpec. TSpecs convey information about the data rate (using a token bucket) and range of packet sizes of the flow in question. However, the TSpec may not be an accurate representation of the resources needed to support the reservation if the router is able to compress the data at the link level. This document describes an extension to the TSpec which enables a sender of potentially compressible data to provide hints to intserv-capable routers about the compressibility they may obtain. Routers which support appropriate compression can take advantage of the hint in their admission control decisions and resource allocation procedures; other routers will ignore the hint. An initial application of this approach is to notify routers performing RTP header compression that they may allocate fewer resources to RTP flows. Working Group Summary The working group supported the publication of this specification. Protocol Quality This document was reviewed for the IESG by Allison Mankin.
