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 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.
