A decade
or so ago, the internet caused its first revolution
by making a new mode of communication available to all,
which was later amplified by the advent of broadband.
From then on, IP networks
have been allowing people to keep in touch in various
ways - e-mail, forums, instant messaging, and even telephony.
HIGHLIGHTS - VoIP

Telephony
over IP |
| |
If
telephony over IP looks set to replace "traditional"
telephony in many enterprises, a lot of it has
to do with its aggressive development.
Its success is due mainly to the slashed prices
of calls made via this technology, in addition
to the numerous services that are accessible.
Videoconference, for example, is a simple operation
in telephony over IP, whereas costly terminals
have to be purchased in classic telephony.
Several protocols are hidden behind this new
medium, guaranteeing the transmission of information
over the network. Telephony over IP, also known
as VoIP, relies on several standardized protocols. |

NETASQ's
solution |
| |
For many years,
NETASQ has considered VoIP an up-and-coming
technology. Even though enterprises are slow
to adopt it now, these protocols will one
day catch up with HTTP in terms of usage.
The real-time aspect of telephony makes the
need for reliable performance critical when
VoIP traffic has to be analyzed. ASQ's ability
to inspect the protocol H323 in real time
ever since 2002 has provided a concrete answer
to the security and performance requirements
that are necessary for VoIP..
In 2005, NETASQ invented "Stateful QoS",
which guarantees the fair distribution of
bandwidth among all users within the same
quality of service rule. This innovation enables
the efficient management of available bandwidth,
which is essential for protocols that are
highly conditioned by their response times.
Every new version of NETASQ products continues
to improve the security of existing protocols
and allows interoperability with new VoIP
protocols. Businesses that are protected by
NETASQ solutions will therefore be ready to
switch over from classic telephony to telephony
over IP.
