News

• 2006.11.07 Backend Scripts have been released
• 2006.12.08 Initial version of Web-based front-end is done (see some of screenshots in below)
  • Kernel image downloading
  • Source-level Kernel compilation (including automatic patching)
  • Filesystem support (we can make a target filesystem on the fly) (FreeBSD and Linux)
  • Boot the target systems using POE (Power Over Ethernet)
  • Ethernet booting with Linux and FreeBSD kernel image and filesystem
  • SQL database integration

• When we will integrate Web-based front-end and backend scripts?

Architecture

• Network Boot Server - deploys a kernel and filesystem to a system on the fly.
• Backend scripts
• Topology generator

Features

• Network Boot Server
  • Linux and FreeBSD kernel and filesystem loading using PXE
  • Remote power on using PoE (Power over Ethernet)
  • Uploading custom kernels, filesystems and patches
  • MySQL database integrated
  • Web-based GUI by using PHP

• Backend Scripts
  • Tuning scripts
  • Background traffic generators
  • Graphing scripts
  • Toy utilities

Download

• Backend Scripts download!
• Web-base GUI (We will release when we finish integrating backend scripts with Web-based GUI.)

Testbed Configuration

• left: sender1 and sender2 (Linux highspeed flow senders ), sender3 and sender4 (Linux background flow senders)
• middle: dummy1 (FreeBSD dummynet router 1), dummy2 (FreeBSD dummynet router 2)
• right: receiver1 and receiver2 (Linux highspeed flow receivers), receiver3 and receiver4 (Linux background flow receivers)
• one control machine (Linux is fine)

How to install Backend Scripts

• You need a dedicated control machine (which can run ssh command to all machines in the testbed)
• Install any linux OSes on all senders and receivers
• Install FreeBSD 5.2.1 or 5.3 at dummynet router 1 and 2. See Dummynet Installation for installing dummynet router 1 and 2.
• Generate a ssh-key and distribute them to all machines, so that the control machine can access all the machines using ssh without password.
• Modify "testbed.conf"
• See the detailed commands in the "plan_all.sample" and make your own "plan_all" file and run it.
