WIDE Camp Demonstrations, September 5th-8th 2006

This page presents the demonstrations held at the WIDE Camp in September 2006.

Introduction

The WIDE Project organizes twice a year a 4-days workshop/meeting for its members, known as the WIDE Camp. This meeting is a good opportunity to have some network expriments and provide nice services to the users.

In this camp, the Nautilus6 project hosts two experiments. In the first one, a multihomed Mobile Router acts as the IPv6 gateway of the network and provides IPv6 connectivity to the camp users. In the second one, a Home Agent service is proposed to the camp users that would like to enjoy IPv6 mobility. The detailed description of each demonstration is described in the following sections:

• Fault-Tolerant network using NEMO Basic Support and Multiple CoA registration
• Home Agent service
• IPv6 contents

The WIDE Camp network offers native IPv6 access. This time, the IPv6 connectivity is provided via a multihomed Mobile Router that acts as the IPv6 gateway of the network. As hundreds of people join the WIDE Camp and use the network, we can expect to test the behaviour of the Mobile Router in a real environment.

Scenario

The Mobile Router uses NEPL (NEMO Platform for Linux) on a 2.6.15.7 Linux kernel with Multiple Care-of Addresses registration support. NEPL is a NEMO Basic Support implementation based on MIPL2 and that has been developped and tested in cooperation between the Go-Core Project (Helsinki University of Technology) and Nautilus6.

The Mobile Router has three egress interfaces connected to three different access technologies. Behind the Mobile Router is connected the whole WIDE Camp network, with hundred of nodes, tens of servers and routers. This Mobile Router provides native IPv6 connectivity to the whole network. All the incoming and outgoing IPv6 traffic will go through this Mobile Router.

The Mobile Router is multihomed: it is connected to the Internet via three egress interfaces, connected to three different access networks. Thanks to the Multiple Care-of Addresses registration support (MCoA), the traffic load can be shared amongst the three access networks by defining some routing policies. Also, in case one of the access network fails, the traffic is redirected from the failed interface to another available one, with a very low delay and a minimum impact to the Camp network nodes. NEMO Basic Support with MCoA support thus allow to recover easily from access network failures, transparently to all the Mobile Network Nodes.

Statistics

Some live statistics can be checked here:

• Latency in the Mobile Network.
• Throughput measurement on the Mobile Router (using SONAR).
• Throughput measurement on the Mobile Router (using BMON, IPv6 only).

How to join the experiment?

It's easy: just use as much as possible the IPv6 connectivity offered during the WIDE Camp (be sure to use the following DNS: 2001:200:0:8470::14).

We also provide dashboards to the MacOSX users: check the IPv6 connectivity and generate few IPv6 traffic (icmp6 echo/reply) with our v6dash dashboard.

In few words we could say that mobility let you change your point of attachment to the Internet without losing your active connection. The change of the IP address induced by the arrival to a new physical network is transparent for the user. In this camp, the Nautilus6 working group demonstrates its Mobility service setup inside of WIDE.

Scenario

The participants of the experience register on the Home Agent and can move naturally from one room to another (with different IPv6 networks) while being reachable all along.

This experiment will use the Operational Home Agent from Nautilus6 (which is currently restricted to Nautilus6 and WIDE members), running NetBSD 2.0.2 with Shisa for the server side.

For the user side, we provide a live CD with many tools related to IPv6 and Mobility to facilitate the use of this service.

Before beeing able to use the mobility service, participants will need to register on the Home Agent.

Statistics

Some live statistics will soon be available here.

How to join the experiment?

To be able to participate to the Mobile IPv6 experience you will need to follow the few steps described below:

• Register to the Operational Home Agent service. You will be prompted for authentication, this is the usual WIDE one.
• Ask for a Home Address, through the web interface.
• Setup your computer to use Mobile IPv6:
• Use a personnalized live CD (easy way): create the live CD through the web interface and burn it. When you boot your computer on the live CD you will be automatically using Mobile IPv6 provided you have IPv6 connectivity.
• Setup MIP6 directly on your computer (hard way): here are some pointers for Shisa (BSD) and MIPL (Linux) users.

Also, because the service is new and still in its testing phase, we'd like the participants to report any issues found either on the Web interface or on the Live CD on the trackers setup for the occasion:

• tracker for the Home Agent web interface
• tracker for the Nautilus6 live CD

In order to generate some IPv6 traffic, you can freely use the following IPv6 contents:

• Check our IPv6 webcam, located in Shin-Kawasaki, Japan.
• Watch one of the following short movies, using IPv6 HTTP streaming: 405, The Movie - The Killer Bean 2 - The Building - The Big Fall

Other IPv6-enabled softwares are available on our software server: for example, KPhone/Piv6 (a a SIP VoIP softphone with IM support for Linux).
