RADVISION Awarded Distributed Multipoint Conferencing Patent

Wednesday February 25, 8:00 am ET

RADVISION's Patent Enables Scalable, Distributed Video Conferencing Deployments
Across Enterprise IP Networks

TEL AVIV, Israel--(BUSINESS WIRE)--RADVISION(R) Ltd. (Nasdaq: RVSN - News), a
leading provider of video network infrastructure and developer tools for unified
visual communications over IP, 3G, and emerging next-generation IMS networks,
today announced it has been granted a U.S. patent, numbered 7,461,126, for
distributed multipoint conferencing with automatic endpoint address detection
and dynamic endpoint-server (MCU) allocation.

The widespread deployment of video conferencing endpoints along with the
increasing use of high definition is driving the need for intelligent management
across the enterprise network. While most enterprises have sufficient bandwidth
in their LANs to support multiple video conference participants, bandwidth
between sites over WAN connections is limited and expensive. Historically,
multiparty conferencing was hosted on large centralized ISDN MCUs but today's IP
environment requires a distributed network of MCUs at each location where there
are concentrations of endpoints.

RADVISION's patented conferencing solution connects users to their "local" MCU
over inexpensive LAN connections and those MCUs connect to each other when
multi-site conferencing is required. This significantly reduces bandwidth use
across expensive WAN connections by creating a large, distributed "virtual MCU"
across the network. This capability becomes more critical with the bandwidth
demands of high definition along with the increasing numbers of room and desktop
video conferencing systems deployed in an enterprise.

When an endpoint first connects to a conference, RADVISION's management system
dynamically assigns the most appropriate MCU on the network to act as the
endpoint's "local" MCU. The management system then automatically creates
connections between individual MCUs as appropriate and manages the multipoint
system topology including determining the connection types (e.g. unicast or
multicast). Bandwidth utilization is significantly enhanced using this
technology. Video conferencing endpoints will send and receive conference media
from the automatically assigned local MCU, which will intelligently manage
sending media to other conference participants on other MCUs. Participants that
are not being viewed by anyone else in the conference will not have their video
stream transmitted across the network, thus conserving bandwidth.

Noted benefits of this patented technology include:

     o    A simplified  approach for deploying a distributed network of multiple
          MCUs for high scalability;

     o    Simple conference entry for all users through a single access number;

     o    Dynamic   conference   creation  across  multiple  MCUs  transparently
          connecting  users to the optimal MCU  according to  location,  network
          topology and administration rules;

     o    Dynamic intelligent setup of cascade connections between MCUs;

     o    Effective bandwidth management across the WAN for conferencing.


"Today's conferencing environment of telepresence, high definition and desktop
video scalability must be deployed and managed in light of today's existing
network infrastructures," said Zeev Bikowsky, General Manager, Networking
Business Unit for RADVISION. "Early on we recognized the importance of
intelligently managing a distributed video network while other companies were
still developing solutions for ISDN. RADVISION's technology breaks new ground
for effectively deploying these demanding applications in today's enterprises."
