A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Differentiated Services Working Group of the IETF.

	Title		: New Terminology and Clarification for Diffserv
	Author(s)	: D. Grossman
	Filename	: draft-ietf-diffserv-new-terms-07.txt
	Pages		: 9
	Date		: 07-Jan-02
	
This memo captures Diffserv working group agreements concerning new
and improved terminology, and also provides minor technical
clarifications.  It is intended to update RFC 2474, RFC 2475 and RFC
2597.   When RFCs 2474 and 2597 advance on the standards track, and
RFC 2475 is updated, it is intended that the revisions in this memo
will be incorporated, and that this memo will be obsoleted by the new
RFCs.

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-ietf-diffserv-new-terms-07.txt

To remove yourself from the IETF Announcement list, send a message to 
ietf-announce-request with the word unsubscribe in the body of the message.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
	"get draft-ietf-diffserv-new-terms-07.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-diffserv-new-terms-07.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

As you have seen in this morning's email, the -07 version of the New Terms 
draft is out.  This will be the final version.  It reflects comments made 
during last call, including:
 -- relationship between SLS and service provisioning policy has been aligned 
with RFC 3198
 -- reference to BCP0037 has been updated
 -- the issue of backward compatibility with RFC 1349 has been clarified.  It 
was pointed out
    that TOS bit processing is present not only in RFC 1812 (router 
requirments) but also in 
    RFC 1122 and RFC 1123 (host requirements).  Since TOS bit processing was 
more pervasive
    in RFC 1812 than I originally thought, specific section references were 
removed.
 -- A clarification of IANA considerations in RFC 2474 was added at the 
request of IANA
 -- All references are marked as "Normative"

In addition, I have slightly modified the title to better reflect the content.

With that, the next step is in the able hands of  the chairs.

Dan

It sounds like your IPv4 experiments have been interesting.
The chairs of the various ICANN groups seem to be changing.
It is not clear how that will impact your results.

Do you use a 2002 prefix ?

Thanks Dan. The request for publication as an Informational RFC is

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Differentiated Services Working Group of the IETF.

	Title		: New Terminology and Clarification for Diffserv
	Author(s)	: D. Grossman
	Filename	: draft-ietf-diffserv-new-terms-08.txt
	Pages		: 10
	Date		: 17-Jan-02
	
This memo captures Diffserv working group agreements concerning new
and improved terminology, and also provides minor technical
clarifications.  It is intended to update RFC 2474, RFC 2475 and RFC
2597.   When RFCs 2474 and 2597 advance on the standards track, and
RFC 2475 is updated, it is intended that the revisions in this memo
will be incorporated, and that this memo will be obsoleted by the new
RFCs.

A URL for this Internet-Draft is:

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-diffserv-new-terms-08.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the

A new version of draft-ietf-diffserv-new-terms has been posted.  It takes care 
of a couple of minor issues that were pointed out by our A-D.  First, the bits 
that are "CU" in RFC 2474 have been assigned for explicit congestion 
notification in RFC 3168, which is standards track.  Previous versions of the 
draft had this usage as experimental.  He also suggested mentioning that OSPF 
use of TOS bits per RFC 1247 was removed in STD 0054.

While I was at it, I also cleaned up some minor formatting problems.

Has anything been done in this WG on setting up bidirectional flows with
Diffserv? RFC2475 says:

     “This architecture only provides service differentiation in one
      direction of traffic flow and is therefore asymmetric.”

I have a prospective service that requires setting up such a bidirectional
flow.

No. Diffserv is unidirectional. If you need the same behavior in both directions,
you simply have to configure it the same way in both directions.

If you think your traffic flows are in fact roughly symmetric, it's easy
enough. If they are in fact asymmetric, it may be better to set up an
asymmetric configuration to optimize resource usage. This is an operational
choice.

In general this sort of discussion fits better on the diffserv-interest
list, but since it goes to the heart of the architecture it seems
appropriate here.

    Brian

P.S. I've just deleted about 6 copies of the infamous MyParty worm from
the diffserv list filter - somebody on this list is spraying us with
multiple copies of it.

this is very much an architectural question, and not the first time is has 
come up. See draft-atarashi-dscp-policy-00.txt

Here's the deal, according to various customers (note the plural) who have 
asked me about it. Suppose that they offer several grades of service at 
various prices to various folks. When a customer approaches a server at a 
given class of service, the server should reply with the same class of service.

Atarashi-san's application (digital libraries and related applications) 
goes on to suggest that the metadata for an object may specify a class of 
service for the reply to over-ride the user class of service; there are 
clearly also other approaches. So her proposal is to have the host mirror 
the user's class of service by default, and provide an override capability 
through the host's API.

An alternative that I have been asked for is that (since the hosts don't 
mirror the class of service) my router should do it for them. As in, 
isolate each incoming session in the router, record the DSCP used incoming, 
and force the outbound DSCP to the same value. Personally, I think that's 
architecturally broken (did anyone mention 'state'?), so we have not done 
that. But something like Atarashi-san's approach is necessary for that 
service to be offered.

Hi,
Take a look at receiver-based traffic control: it's based on ECN, and can
work for TCP traffic.
I'm not aware about the availability of this approach.

Has anything been done in this WG on setting up bidirectional flows with
Diffserv? RFC2475 says:

     "This architecture only provides service differentiation in one
      direction of traffic flow and is therefore asymmetric."

I have a prospective service that requires setting up such a bidirectional
flow.

Hi,
I have used ucd-snmp package and I have written an snmp agent that supports 
the IETF's
diffserv MIB (version 0.4).
I can set a mib value at the snmpd memory space,
but the value must be set at an appropriate entry to the kernel.
Is there is an implementation for setting the IETF MIBs parameters to
the Linux kernel using the netlink interface? Linux kernel supports different
utilities (qdisc, class, filters and policing); therefore there is the need 
to translate the MIB to
these elements and to use netlink. Have anyone done this?

Thank you in advance,

Leonidas

I would try the diffserv implementation list for this question

In response to my question about bidirectional flows, Fred Baker didn’t want
to impose the requirement on the routers to mark return packets because that
would mean keeping state info on every flow.  I sympathize with the desire
to avoid complicating the switch but:

If the system is going to allow DSCP marking to affect packet treatment, the
access router is going to have to be a gatekeeper to ensure that such
markings aren’t abused.  Otherwise most spam will be sent at high priority.
One would assume that Service Providers will want to limit use of and/or
charge for high priority markings.  This creates a state-keeping burden that
can’t be avoided.  If UserA has premium service, and sends a packet to
ServerX, packets from ServerX to UserA should get that premium service but
not packets from ServerX to other users.  The only way for the network to
validate these service requests is to note the packet from UserA to ServerX,
keep this state, and allow ServerX to UserA traffic to use this Diffserv
marking.

If IP is to be the global data/voice network of the future, I think
emergency services (and bidirectional flows) are going to be an unavoidable
part of the package even though it complicates the switch.

As I remember, when the Diffserv WG was first set up, allowing SPs to create
a premium service was a major driver for the WG.  This was presumed to
include web browsing.  Web browsing with Diffserv only makes sense if
priority is given to the return packets.

I believe the points you raise are all discussed in RFC 2475.

Hi Steve,
I believe, that at the momoment it is more technical than diff-serv
standarization problem.
If you group your users say into 2 groups, using addressing, every router
in your network will know exactly how to treat returning packet: if your
customer belongs to "priority" group then he will get priority treatment
even for return traffic, if it belongs to "standard" group he will get
"standard" treatment. And so on.
It will easily work in your AS, and no "states" need to be introduced.

If you want to have such treatment all over internet, then you need to
think about such solutions as receiver-based traffic control.

Andrzej,

Even for a single service provider's network, your suggested approach is not
trivial to implement. You have to proxy on EVERY edge router for the
"priority" groups and "non-priority" groups. How can it be provisioned?

Hi,
I hope you agree, that it has to be provisioned only in the places where it
makes sense -> where you have scare resources and where you need to
differentiate treatment of the traffic, eg. to schedule it differently or
route it to different TE-tunnel (with different traffic parameters) -> I
hope that none will claim that's the violation of diffserv architecture.
Openly, with xDSL concetrators/routers the gain of implementation of
complicated scheduling mechanism would probably be to high to be returned.
This approach reduce the number of routers where you configure treatment
per group of users.

rgrds,
Andrzej

Would the access links be the most likely congestion points to protect?

Hi,
I hope you agree, that it has to be provisioned only in the places where it
makes sense -> where you have scare resources and where you need to
differentiate treatment of the traffic, eg. to schedule it differently or
route it to different TE-tunnel (with different traffic parameters) -> I
hope that none will claim that's the violation of diffserv architecture.
Openly, with xDSL concetrators/routers the gain of implementation of
complicated scheduling mechanism would probably be to high to be returned.
This approach reduce the number of routers where you configure treatment
per group of users.

Hi Steve,
I believe, that at the momoment it is more technical than diff-serv
standarization problem.
If you group your users say into 2 groups, using addressing, every router
in your network will know exactly how to treat returning packet: if your
customer belongs to "priority" group then he will get priority treatment
even for return traffic, if it belongs to "standard" group he will get
"standard" treatment. And so on.
It will easily work in your AS, and no "states" need to be introduced.

If you want to have such treatment all over internet, then you need to
think about such solutions as receiver-based traffic control.

The difference is that the proxy is receiver-based. You cannot predict from
where you will get the traffic; you have to provision on every edge router.
If it is source-based, you can probably only provision on selected routers
where the priority traffic would come from.

It is worth to compare the cost "traditional" ATM-based xDSL contentrator
working over costly SDH metro network with the cost of Long Reach Ethernet
with optical (most atractive option)ethernet uplink. I expect technology
shift in the access, where you will have plenty of cheap btw, and cheaper
backbone (instead of costly ATM interfaces cheap ethernet interfaces).
So, I do not expect congestion points in the access, contradictory to
common opinion.

Hi everybody,

I have a little question for you. How does the PDP uses the capabilities
information reported by the PEP's request message?
Do you have an exemple?

Thanks. 

You can mail to debernar@cefriel.it
