Subject: Please ask your WG... 

To volunteer for the nomcom.
The nomcom process is (in my opinion) better served by a large pool of
volunteers drawn from a wide spectrum of IETF attendees.
As such, please ask on your individual mailing lists for folks to
volunteer.

Obviously, the exact method for doing so is up to you.
The most recent call for volunteers can be reference here:
    https://datatracker.ietf.org/public/show_nomcom_message.cgi?id=1617
Whether you copy that message, or reference is probably up to you and
the
habits of your working group mailing list.
If you want to reference or copy the status message I sent out, that can
be found at:

Re: WGLC: draft-ietf-behave-dccp-01

Hi Remi,

Here are some comments.

Tom P.

Section 4.3:

"o  The filtering behavior for DCCP MAY be independent of the filtering
behavior for UDP."

Shouldn't that be "for UDP or any other protocol" or something similar.
Certainly it's acceptable for the DCCP filtering behavior to be
independent of TCP...

"REQ-4: A NAT MUST NOT respond to an unsolicited inbound DCCP-Listen
packet for at least 6 seconds after the packet is received."

What does "not respond" mean?  Not send the ICMP message? Not forward
the DCCP-Listen packet?  Both?  Maybe this could be clearer if it's
reworded in a positive vein -- "Upon receiving a DCCP-Listen packet a
NAT MUST..."

Section 5, REQ-5:

Is this saying that the "established connection idle timeout" cannot be
configured to be less than 2 hours 40 minutes?  I see this language is
stolen directly from behave-tcp, but I find it confusing.

Section 6:

Tom - could you forward this and the previous mails to the dccp list 
(the IETF mail server is bouncing me due to a local DNS problem, which 
has just been fixed but may taked a week to reach all DNS caches!)

Working group last call for service codes

Hi All,

This is to announce the beginning of working group last call for "The
DCCP Service Code", draft-ietf-dccp-serv-codes-06.txt (see
http://www.ietf.org/internet-drafts/draft-ietf-dccp-serv-codes-06.txt).
Last call will run for two weeks, ending Monday, 8-Sep.

Please send detailed comments to the list.  Also, bare "I support" or "I
don't support" e-mails are quite useful.

Re: Working group last call for service codes

My favorite thing in this new draft is the specific way you have identified 
changes to RFC4340.  Thanks!

Detailed comments.

    Service Codes allow a flexible correspondence between application-
    layer services and server port numbers, which affects how
    applications interact with DCCP. This decouples the use of ports for
    connection demultiplexing and state management from their use to
    indicate a desired service. An application identifies the requested
    service by the Service Code value in a DCCP-Request packet. Each
    application may listen on one or more ports associated with one or
    more Service Codes ([RFC4340], section 8.1.2).

=> This goes too far and may confuse readers.  Remember that ports are still 
primary.  Prefer:

    Service Codes allow applications to declare exactly which services
    are associated with server port numbers.  This can affects how
    applications interact with DCCP. ... Each application specifies
    one or more Service Codes for each listening port ([RFC4340], section
    8.1.2).

Do not capitalize Middleboxes except at the beginning of a sentence.

"Middleboxes that desire to identify the type of data being transported by a 
flow," => prefer "the type of data a flow claims to transport."  Since 
middleboxes can't, of course, trust the service code.  But you do make this 
clearer later on.
