Load Balancing Behavior in Cisco Unified MeetingPlace Web Conferencing

Allow External Web

This meeting is reserved for internal attendees only. When the first attendee launches the meeting

No

 

web server with the fewest currently active meetings in the internal cluster. This web server now owns

 

 

the meeting. Subsequent attendees may be directed to any internal web server when they join the web

 

 

conference.

 

 

Allow External Web

This meeting is accessible to external attendees, that is, participants attending from outside the

Participants is set to

firewall.

Yes

 

If the first attendee attempts to join the web conference from an external web server, Cisco Unified

 

 

 

 

MeetingPlace Web Conferencing directs the web-conferencing session to the web server with the

 

 

fewest currently active meetings in the external cluster. This web server now owns the meeting.

 

 

If the first attendee attempts to join the web conference from an internal web server, Cisco Unified

 

 

MeetingPlace Web Conferencing determines if it has an associated external web server. Such

 

 

information is found on the Web Server Properties administrative page in the DMZ Web Server field.

•If there is an entry in the DMZ Web Server field, Cisco Unified MeetingPlace Web Conferencing performs a redirection to that external server.

•If Cisco Unified MeetingPlace Web Conferencing does not find an entry in the DMZ Web Server field, the web-conferencing session is directed to the least loaded internal server as described for internal meetings. All subsequent attendees are directed to an internal web server for their web conference.

Internal users can join both internal meetings and external meetings. If a meeting is designated as external, internal users who log in to an internal web server are redirected to an external web server.

External users can join only external meetings on external web servers.

Recommendations for a Robust Cisco Unified MeetingPlace System

To ensure a robust system with redundancy and failover, we recommend that you have the following:

•An internal web cluster.

•An external web cluster.

•A dedicated remote SQL Server system for each cluster.

•Remote storage location with an appropriately sized RAID array and a comprehensive backup policy.

End-User Experience During Meeting Console Failover

When failover occurs on a system that is configured for redundancy and failover, users will experience the following behavior:

1.The web server to which the participant is connected stops responding (for example, the computer loses power or the Web Conferencing services are shut down).

2.Users who are connected to the edge server on that web server lose their connection to the meeting.
