Network Security
System security can be enhanced by separating the Media, Signaling and Management
Networks.
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 Collaboration Server.
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.
For more information see the RealPresence Collaboration Server (RMX) 1500/2000/4000
Deployment Guide for Maximum Security Environments, Enable Network Separation (RMX 2000).
Multiple Network Services
Media, signaling and management networks can be physically separated on the
Collaboration Server 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 media and signaling networks can be defined for the RealPresence Collaboration Server
(RMX) 4000, or for the RealPresence Collaboration Server (RMX) 2000 and two for the
RealPresence Collaboration Server (RMX) 1500. Multiple IP Network Services can be defined, up
to two for each media and signaling network connected to the Collaboration Server. The
networks can be connected to one or several Media cards in the Collaboration Server unit.
The Management Network is logically and physically separated from the media and signaling
networks. There can be one Management Network defined per Collaboration Server system.
Each conference on the Collaboration Server can host participants from the different IP
Network networks simultaneously.
