Network Security - Polycom realpresence 1800 Administrator's Manual

Network Security

System security can be enhanced by separating the Media, Signaling and Management Networks.
Collaboration Server (RMX) 4000
On the 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.
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.
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 Procedure 5: Enable Network Separation (RMX 2000) in the RealPresence
Collaboration Server (RMX) 1800/2000/4000 Deployment Guide for Maximum Security Environments.
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 Collaboration Server (RMX) 4000, or four
for the RealPresence Collaboration Server (RMX) 2000 and two for the Collaboration Server (RMX) 1800.
Multiple Networks are not supported by Collaboration Server (RMX) 1800 with no DSP cards.
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.
