1.   Introduction

This monthly report summarizes the ns-3 project, a collaborative project funded under the following grants:

• NSF CNS-0551686 (University of Washington)
• NSF CNS-0551378 (Georgia Institute of Technology)
• NSF CNS-0551706 (International Computer Science Institute)

1.1 News and Highlights

• This project was officially started on 1 July, 2006.
• The project intends to hold a small kickoff and design review meeting at ICIR on August 9-11 (by invite only).

1.2 Contributions and Collaborations

We regularly collaborate with the Planete research group at INRIA Sophia Antipolis.

• Mathieu Lacage met with George Riley at INRIA Sophia Antipolis on June 9 to discuss ns-3 architecture. Mathieu updated yans documentation as a result of the meeting, and summarized the meeting outcomes. These are being incorporated into the forthcoming ns-3 technical spec.

Jim Martin from the CS department at Clemson University intends to collaborate with us on DOCSIS and WiMax models for ns-2 and ns-3, and also to participate in wireless architecture definition for ns-3.

1.3 Statistics

• There were ~4000 downloads of ns-2 from Sourceforge in the past month.
• There were 360 posts to the ns-users mailing list and 22 posts to the ns-developers mailing list in the past month.
• There are 19 open bugs on the ns-2 tracker

2.3 Actions and Open Issues

Develop and circulate a proposed initial development schedule

Owner: Tom H.

Description: Update what was put into the proposal.

Status: No change since last month. Note: Jim Martin also requesting this now.

Start a project web site and source code control server.

Owner: George R.

Description: We need an operational web server, tracker (bugzilla), and source code control server.

Status: Agreement to use Ga. Tech to supply and administer servers. Tom registered the nsnam.org domain. Waiting for Georgia Tech now to set up the machines.

Announce the project.

Owner: Tom H.

Status: Will be announced in beginning of July.

New tinderboxes for better validation build environment

Owner: Tom H.

Status: Planning to use UW machines for this-- will probably start to set up in August. Until then, continue using Sourcefoge and ad-hoc machines.

3.   ns-2 Maintenance

The project is maintaining ns-2, nam-1, otcl, and tclcl while ns-3 is being developed.

• ns-2
• nam-1
• otcl and tclcl

3.1 Release Schedule

Planning the next release of ns-2 and related packages in August 2006.

Planned features (see the ns-2 changelog):

• SCTP code update
• Major XCP code cleanup
• TFRC updates
• Adding DelayBox and PackMimeHTTP models

Remaining major issues:

• Certain validation tests are failing on several platforms
• Updating the configure scripts to handle newer platforms
• nam-1 relicensing

We plan to make quarterly maintenance releases starting in January 2007.

3.2 Technical Progress
