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 Default IP Network Service and the Management Network Service 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 a media 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 1800
On the RealPresence Collaboration Server 1800 the Default IP Network Service and the Management
Network Service have been logically and physically separated from each other to provide enhanced
security. The Collaboration Server 1800 includes two LAN ports that can be used for separating the
management network from the signaling and media network or if Multiple Networks option is enabled, each
LAN port is used for signaling, media and management per Network Service.
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, Procedure 5: 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 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) 1500/1800.
