Available NS-2 patches for DCCP

Hello,

I was reading through the project meeting minutes from the last meeting 
in IETF 73 and noticed that there was a request for hearing from people 
testing/implementing CCID4. As our work involves rate control issues 
this might be something we could be interested in. Rather than reinvent 
the wheel I would like to know whether there were any available older 
ns-2 patches for FR/QS/CCID3/CCID4 from where to work forward from?

For example in "Performance of VoIP using DCCP over a DVB-RCS Satellite 
Network" paper there was a mention of CCID4,Faster Restart and QS 
implemented on NS-2.

Best regards,

I-D Action:draft-ietf-dccp-simul-open-07.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Datagram Congestion Control Protocol Working Group of the IETF.

	Title           : DCCP Simultaneous-Open Technique to Facilitate NAT/Middlebox Traversal
	Author(s)       : G. Fairhurst
	Filename        : draft-ietf-dccp-simul-open-07.txt
	Pages           : 32
	Date            : 2009-02-13

This document specifies an update to the Datagram Congestion Control
Protocol (DCCP), a connection-oriented and datagram-based transport
protocol.  The update adds support for the DCCP-Listen packet.  This
assists DCCP applications to communicate through middleboxes (e.g. a
DCCP server behind a firewall, or a Network Address Port Translator),
where peering endpoints need to initiate communication in a near-
simultaneous manner to establish necessary middlebox state.

I-D Action:draft-ietf-dccp-quickstart-02.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Datagram Congestion Control Protocol Working Group of the IETF.

	Title           : Quick-Start for Datagram Congestion Cntrol Protocol (DCCP)
	Author(s)       : G. Fairhurst, A. Sathiaseelan
	Filename        : draft-ietf-dccp-quickstart-02.txt
	Pages           : 22
	Date            : 2009-03-03

This document specifies the use of the Quick-Start mechanism by the 
Datagram Congestion Control Protocol (DCCP).  DCCP is a transport 
protocol that allows the transmission of congestion-controlled, 
unreliable datagrams.  DCCP is intended for applications such as 
streaming media, Internet telephony, and on-line games.  In DCCP, an 
  application has a choice of congestion control mechanisms, each 
specified by a Congestion Control Identifier (CCID). This document 
specifies general procedures applicable to all DCCP CCIDs and 
specific procedures for the use of Quick-Start with DCCP CCID-2, 
CCID-3 and CCID-4.  Quick-Start enables a DCCP sender to cooperate 
with Quick-Start routers along the end-to-end path to determine an 
allowed sending rate at the start of a connection and, at times, in 
the middle of a DCCP connection (e.g., after an idle or application-
limited period).  The present specification is provided for use in 
controlled environments, and not as a mechanism that would be 
intended or appropriate for ubiquitous deployment in the global 
Internet.

New revision of QS for DCCP: draft-ietf-dccp-quickstart-02.txt


This email is pleased to announce a new revision of the Quick-Start 
spec. for DCCP. This draft follows a detailed review by the authors, as 
well as inputs from several people in this and TSV groups. There are 
many changes to the text - but very little change to the protocol 
specification (the aim was to simplify the document and be more 
consistent between CCID-2 and CCID-3).

The draft may be found at:
http://tools.ietf.org/html/draft-ietf-dccp-quickstart-02

And a diff also at:
http://tools.ietf.org/rfcdiff?url2=http://tools.ietf.org/id/draft-ietf-dccp-quickstart-02.txt

We as authors are now happy with this document and would like to invite 
any interested people to send comments or questions - either directly to 
us, or via the DCCP list. We are also actively looking for people who 
can commit to review this draft as part of a future WGLC - would you be 
able to help?

Best wishes,

gorry and arjuna
