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 three media and signaling networks can be defined for the RealPresence Collaboration
Server 800s for each media and signaling network connected to the Collaboration Server.
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.

Resource Allocation and Capacity

The Resolution Configuration settings are configured per MCU and affect the resource
capacity of the MCU. They are reflected in the port gauges displayed on the Collaboration
Server management application's main screen.
In Multiple Networks mode, the port gauges do not reflect the resource availability per
Network Service.
Polycom, Inc.
Multiple Services system mode is a purchasable option and it is enabled in the MCU
license.
Multiple Services system mode is enabled when the system configuration flag
MULTIPLE_SERVICES is added and set to YES.
On the RealPresence Collaboration Server 800s, LAN redundancy cannot be enabled in
parallel to Multiple Networks and the LAN_REDUNDANCY flag must be set to NO
when the Multiple Networks option is enabled.
Participants on different networks can connect to the same conference with full audio,
video and content capabilities.
Traffic on one network does not influence or affect the traffic on other networks
connected to the same MCU. If one network fails, it will not affect the traffic in the other
connected networks.
The Signaling Host IP Address and the Media IP Address cannot be different.
Maximum number of services that can be defined per Collaboration Server platform:
A DNS server can be specified for each IP Network Service and for the Collaboration Server
Management Network Service.
— In the Network Services that do not include the DNS, use the IP addresses of the
various devices to define them in the Network Services.
Participants are associated with a Network Service and use it resources as follows:
— Dial-in participants - according to the network used to place the call and connect to
the Collaboration Server.
— Dial-out participant - according to the Network Service selected during the
participant properties definition or during conference definition, according to the
Network Service selected as default.
