Emulab will be unavailable on Saturday, July 26th from 6-10AM MDT
Emulab is a network testbed, giving researchers a wide range of
environments in which to develop, debug, and evaluate their systems.
The name Emulab refers both to a facility and to a
software system.
The primary Emulab installation is run
by the
Flux Group, part of the
School of Computing at the
University of Utah.
There are also installations of the Emulab software at more than
two
dozen sites around the world, ranging from testbeds with a handful
of nodes up to testbeds with hundreds of nodes.
Emulab is widely used
by computer science researchers in the fields of networking and
distributed systems.
It is also used to teach
classes in those fields.
Emulab is a public facility, available without charge to most
researchers worldwide.
If you are unsure if you qualify for use, please see our
policies document,
or ask us.
If you think you qualify, you can
apply to start a new
project.
Emulab provides integrated access to a wide range of experimental
environments:
- Emulation
- An emulated experiment allows you to specify an arbitrary network
topology, giving you a controllable, predictable, and repeatable
environment, including PC nodes on which you have
full "root" access, running an operating system of
your choice.
- Live-Internet Experimentation
- Using the RON and PlanetLab
testbeds, Emulab provides you with a
full-featured environment for deploying, running, and
controlling your application at hundreds of sites around the
world.
- 802.11 Wireless
- Emulab's 802.11a/b/g testbed is deployed on multiple floors of an
office building. Nodes are under your full control and may act as
access points, clients, or in ad-hoc mode. All nodes have two wireless
interfaces, plus a wired control network.
- Software-Defined Radio
- USRP devices from the GNU Radio project give you control over Layer 1 of a
wireless network - everything from signal processing up is done in
software.
- Sensor Networks
- Emulab's sensor network testbed includes 25 Mica2 motes. All motes
are equipped with a serial port, for maximum control and debugging
capability.
- Mobile Wireless
- A fleet of six Garcia robots from Acroname are equipped with Stargate
single-board computers and Mica2 motes. These robots have
full mobility within our sensor network testbed.
- Simulation
- Using NSE, ns-2's emulation facility, simulated networks can interact
with real networks; not only the emulator, but any network
resource in Emulab.
Emulab unifies all of these environments under a common user interface,
and integrates them into a common framework. This framework
provides abstractions, services, and namespaces common to all, such as
allocation and naming of nodes and links. By mapping the abstractions
into domain-specific mechanisms and internal names, Emulab masks much
of the heterogeneity of the different resources.
