" e procurement of these capabili-

However, DISA can only do so much
through its own e orts. To truly enable
enterprise UC, the military services are
responsible for putting their networks
on an IP path so that systems can achieve interoperability.
"DISA has been working with the DOD CIO and our mis-
sion partners at the service, combatant command and agency
levels," said Army Col. David Grauel, DISA s deputy program
executive o cer for enterprise services. " ese mission part-
ners have begun their own local transitions to UC-type solu-
tions. But we realize that not everybody has the same set of
circumstances. ey ve all got unique mission sets, timelines,
budget constraints and interests."
A MORE COLLABORATIVE ENVIRONMENT
UC encompasses a broad range of communications, includ-
ing voice, video, instant messaging/chat, voice mail and
email. According to Grauel, UC will include myriad services
on the unclassi ed and classi ed side, including enterprise
voice-over-IP (VOIP), global video services, IP video, Web
conferencing and uni ed messaging. ose services will
also be interoperable with DOD s enterprise email o ering
hosted by DISA.
"We re creating a exible environment where these servic-
es, for example, can choose the particular user experience
that they want for their particular service," Grauel said. "And
it will work together with our enterprise o erings --- such
as enterprise directories, as one example. It really is a great
opportunity to bring this all together and deliver a set of
capabilities that will improve the e ciency and productivity
of our DOD workforce."
Enterprise VOIP is designed to provide a full range of
voice-related capabilities to more than 2.7 million DOD us-
ers that take full advantage of DISN and IP technologies.
e purpose is to avoid the duplication of costs for voice
services, operations and maintenance, network operations,
sustainment and information assurance at nearly 2,000
locations worldwide with a lower total cost of ownership.
Enterprise classi ed VOIP is available today over the core
network, and before the end of the calendar year, it will be
available over satellite communications, Sebastian said.
Uni ed messaging integrates voice-mail and email capa-
bilities, thereby enabling subscribers to access voice mail via
email or email via voice mail. She added that uni ed mes-
saging would be turned on by the end of the year.
UC services are driven by emerging IP and changing com-
munications technologies, which recognize evolving com-
munication capabilities from point-to-point to multipoint,
voice-only to rich-media, multiple devices to a single device,
wired to wireless, non-real time to real time, and scheduled
to ad hoc.
" ese capabilities absolutely will all be integrated into
various client experiences and feature sets that support both
the needs of the user and the resource con guration of the
environment," Sebastian said. "For example, we ve demon-
strated an IP video capability in a mobility pilot. e IP
video solution that we re rolling out works in a resource-
constrained environment and on multiple platforms."
ese kinds of enterprise services will be consumed via
a variety of end-user equipment, such as computers, IP
phones and mobile devices. Combined together, these ca-
pabilities will result in ubiquitous access to services by any
user at any location on any approved device.
" ere are pieces of UC that are very centralized that we
do across the core infrastructure, and then there are other
things, like applications, that are deployed on a device or
close to the edge for rich content," Sebastian said. " e piec-
es of UC are going to be placed based on where they need to
be for maximum performance."
Several of the UC capabilities are being introduced into
the operational environment and can be used as indepen-
dent capabilities today. Many others are in the planning
phase and are being scheduled for pilot releases.

The beauty of IP convergence
is that voice, video and
all these cool applications
operate and interoperate
across the IP network.
