RealPresence Collaboration Server (RMX) 1500/RealPresence
Collaboration Server (RMX) 4000
On the RealPresence Collaboration Server (RMX) 1500 and RealPresence Collaboration
Server (RMX) 4000, Media, Signaling and Management Networks are physically separated to
provide enhanced security. The IP Network Service and the Default Management Network have
been logically and physically separated from each other. In the IP Network Service each IP
address is assigned a physical port and media (RTP) inputs are routed directly to an MPM+
or MPMx card. This provides for a more secure network with greater bandwidth as each
media card has its own dedicated port. All signaling communications are processed on a
single stack of the processor in the RMX.
RealPresence Collaboration Server (RMX) 2000
On the RealPresence Collaboration Server (RMX) 2000 a RTM LAN or RTM ISDN card is
required to enable the separation between the networks. By defining Multiple Network
Services, a separate network can be defined for each media card installed in the system.
Multiple Network Services
Media, signaling and management networks can be physically separated on the RMX
system to provide enhanced security. This addresses the requirement in an organization
that different groups of participants be supported on different networks. For example, some
participants may be internal to the organization while others are external.
Up to eight media and signaling networks can be defined for the RealPresence
Collaboration Server (RMX) 4000, or four for the RealPresence Collaboration Server (RMX)
2000 and two for the RealPresence Collaboration Server (RMX) 1500. Multiple IP Network
Services can be defined, or up to two (RealPresence Collaboration Server (RMX) 1500)for
each media and signaling network connected to the RMX. The networks can be connected to
one or several Media cards in the RMX unit.
The Management Network is logically and physically separated from the media and signaling
networks. There can be one Management Network defined per RMX system.
Each conference on the RMX can host participants from the different IP Network networks
simultaneously.
The following figure shows the network topology with three different media and signaling
networks and one Management network connected to the RealPresence Collaboration
Server (RMX) 4000.
