Internet2 Testbed
PROJECT GOALS
• To implement and test Internet2 connections capable of
transmitting full broadcast quality video streams using MPEG2
video encoding and decoding technology between remote collaborative
sites.
• To establish a 24 hours live, continuous, stereo-feed between
the M.I.N.D lab at Michigan State University and other remote
research sites.
• To support network-based applications that require the
sharing of stereo video signal from head-worm, stereo cameras
and displays.
DESCRIPTION
The Internet2 testbed is an important component of the Teleportal
Project. It serves as the communication channel that networks
in real time the Teleportal Rooms between the MSU M.I.N.D
Lab and remote sites making it possible for users of the system
to share information.
The internet2 testbed aims to support real time remote collaboration
by allowing the sharing of bi-directional video streams capable
of carrying volumetric medical, engineering, and scientific
data.
Some of the hardware components being used in the Internet2
testbed are:
Amnis Network Attached video Transmitters and Receivers.
These devices can be reconfigured to support different encoding
and decoding bit rates:
Encoder
MPEG –1 : 56 kbps to 5 Mbps
MPEG- 2: 2 to 12 Mbps - High Quality
MPEG –2 : 2.1 to 4Mbps - Ultra Low Latency
Decoder
MPEG -1: 56 kbps to 4 Mbps
MPEG- 2: 2 to 8 Mbps - High Quality
MPEG –2: 2 to 4 Mbps - Ultra Low Latency
These devices are networked at the MSU M.I.N.D Lab and connect
to remote sites by using a Cysco Catalyst 1900-10 Base-T switch
and a Foundry Switch FastIron Workgroup Swithc-100 BaseT.
Video stream traffic to and from MSU M.I.N.D Lab is routed
thru the Michnet Merit backbone network using an Abilene connection
of 622 Mbps (OC12c)
