It needs to be possible to set the 6 bits of the DSCP independently of either the flow label or the ECN bits. Ditto the flow label. If the proposed APIs can't do that, they are inadequate. > > 3) What about APIs for IPv4? Aren't they needed too? I thought that you could set the TOS byte in the v4 API.

It's been debated, but in the general case it is desirable. The DSCP bits may be set within the stack by a QOS manager, or downstream by a router, but apps should have the ability in principle. The flow label may be set within the stack, or in principle by the app. Brian > > Have a look at > > draft-ietf-ipngwg-rfc2553bis-07.txt and > draft-ietf-ipngwg-rfc2292bis-07.txt > > for the details of what has been specified so far. > > Thoughts of what (if anything more) should be done with APIs for > diffserv would be appreciated. > > Thomas > _______________________________________________ > diffserv mailing list > diffserv@ietf.org > https://www1.ietf.org/mailman/listinfo/diffserv > Archive: http://www.ietf.org/mail-archive/working-groups/diffserv/current/maillist.html -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Brian E Carpenter Distinguished Engineer, Internet Standards & Technology, IBM On assignment at the IBM Zurich Laboratory, Switzerland _______________________________________________ diffserv mailing list diffserv@ietf.org https://www1.ietf.org/mailman/listinfo/diffserv Archive: http://www.ietf.org/mail-archive/working-groups/diffserv/current/maillist.html From mailnull@www1.ietf.org Tue Oct 15 23:57:30 2002 Received: from www1.ietf.org (ietf.org [132.151.1.19] (may be forged)) by ietf.org (8.9.1a/8.9.1a) with ESMTP id XAA23188 for ; Tue, 15 Oct 2002 23:57:30 -0400 (EDT) Received: (from mailnull@localhost) by www1.ietf.org (8.11.6/8.11.6) id g9G3xIa28042 for diffserv-archive@odin.ietf.org; Tue, 15 Oct 2002 23:59:18 -0400 Received: from www1.ietf.org (localhost.localdomain [127.0.0.1]) by www1.ietf.org (8.11.6/8.11.6) with ESMTP id g9G3mwv27613; Tue, 15 Oct 2002 23:48:58 -0400 Received: from ietf.org (odin.ietf.org [132.151.1.176]) by www1.ietf.org (8.11.6/8.11.6) with ESMTP id g9FL4qv09059 for ; Tue, 15 Oct 2002 17:04:52 -0400 Received: from netcore.fi (ietf-mx.ietf.org [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id RAA15903 for ; Tue, 15 Oct 2002 17:02:36 -0400 (EDT) Received: from localhost (pekkas@localhost) by netcore.fi (8.11.6/8.11.6) with ESMTP id g9FL4ed05865; Wed, 16 Oct 2002 00:04:41 +0300 Date: Wed, 16 Oct 2002 00:04:40 +0300 (EEST) From: Pekka Savola To: Brian E Carpenter cc: Thomas Narten , , , Jun-ichiro itojun Hagino Subject: Re: [Diffserv] APIs for diffserv In-Reply-To: <3DAC7C39.A17C7C3C@hursley.ibm.com> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: diffserv-admin@ietf.org Errors-To: diffserv-admin@ietf.org X-BeenThere: diffserv@ietf.org X-Mailman-Version: 2.0.12 Precedence: bulk List-Unsubscribe: , List-Id: Diffserv Discussion List List-Post: List-Help: List-Subscribe: , On Tue, 15 Oct 2002, Brian E Carpenter wrote: > Thomas Narten wrote: > > > > The IPv6 basic and advanced APIs include placeholders/hooks for > > specifying the Flow Label on outgoing IPv6 packets.

That is slightly contentious. The flow-label draft does not define use cases, but if that draft is approved in its present form I know how to define a diffserv use case for the flow label (and there are several other use cases). However, it shouldn't affect the socket API discussion.
