US Department of Energy Develops QoS Technology for Internet Traffic
The US Department of Energy national laboratories has announced that it has
successfully marked select Internet traffic for priority service over
unmarked, lower-priority traffic in a cross-country demonstration. The
demonstration involved sending two video streams over an intentionally
congested Internet path from Berkeley, California to Argonne, Illinois.
The priority marked video stream moved at eight frames per second, while
the unmarker version transmitted at just one frame per second.
Software was used to mark the priority traffic with special router commands
that give the marked packets priority over packets which are not similarly
marked. The path between Berkeley and Argonne also employed software that
could recognize the priority marked data packets.
The demonstration used a combination of technologies from Berkeley and
Argonne labs, Cisco Systems and Sprint Telecommunications. The technology
for priority packets was developed at the Berkeley Lab. Priority packets as
well as class-based queuing and many of the original ideas for
differentiated services was initiated from research done by Van Jacobson
and his Network Research Group at Berkeley Lab.
Panasonic and FaxSav Unveil Internet Fax Machine
Panasonic introduces the IQ-Fax, a feature that enables users of
Panasonic’s SoHo line of fax machines to access the FaxSav Internet fax
network with the push of a button. To use the IQ-Fax feature, users will
place a document into the fax machine’s feeder, push the IQ-Fax button,
dial any fax number in the world and press the send button. The document
is then sent via the FaxSav Internet fax network to its destination.
Users of the FaxSav network will have the option to receive a confirmation
indicating that a fax has been delivered. If the receiving fax machine is
unavailable, the FaxSav network will automatically re-send a fax until it
is sent. Users will receive notification if a fax transmission was not
possible. The FaxSav network also provides RSATM encryption to ensure that
fax transmissions are secured and confidential.
The IQ-Fax feature will be included with all of Panasonic’s 1998 SoHo line
of fax machines.
NetPhone and Cabletron Team to Develop Voice and Data Switches
NetPhone has announced a partnership with Cabletron Systems to integrate
its VoIP technology into Cabletron’s SmartSwitch 2000, 6000, and 9000
models. The VoIP technology will translate voice traffic into data packets
to enable existing computer networks to simultaneously support voice and
data communications. Cabletron is offering the VoIP technology as a plug-in
module, the SmartVoice HSIM (High Speed Interface Module), for its
switches, or as a stand alone VoIP platform.
The VoIP solution will enable up to 24 simultaneous phone calls to be
connected over an IP based corporate intranet or data center. It is
manageable via Cabletron’s SPECTRUM enterprise management platform.
SmartVoice technology is expected to be available by Fall. A SmartVoice
plug-in module is priced at $6,995. The SmartVoice stand alone solution is
priced at $7,995 US.
Advanced Research of Technologies to Distribute ArelNet’s IP Technology
Advanced Research of Technologies (ART) has announced that it will
distribute ArelNet’s i-Tone IP telephony gateway solution. ART plans to
market the voice/fax over IP solution to ISPs, carriers and integrators in
The i-Tone voice/fax over IP solution utilizes a carrier grade
gateway/gatekeeper architecture to manage more than 6000 ports and more
than 1 million queries per day. It is H.323 compliant to provide
interoperability with other H.323 compliant products. The product employs
DSP based processing to support voice codecs such as G.711, G.723 and
G.729. The gateway will provide connectivity from phone to phone, fax to
fax, or PC to phone. In addition, it provides store and forward services
such as PC to fax, email to fax and fax broadcasting. Its modular
architecture will enable users to expand service functionality
incrementally by adding modules as needed.
The i-Tone’s network management system (NMS) module enables the centralized
management of a network from local or remote locations. The NMS enables
administrators to manage intelligent routing, routing tables, system
configuration, scheduling tables and stored customer data.
The i-Tone system also includes a billing module that is customizable to
meet the operator’s requirements. It features inter-billing, reporting,
secured data transfer and calling card services. The solution will also
interface with existing billing solutions to provide CDR data exporting
