This table reports the content that clients have
subscribed to the CDM-IP using the IGMP protocol.
This allows a user to determine which services are
being used and the minimum time before a service will
be terminated.
CDM-IP as Server:
IGMP query period
Q
The IGMP protocol requests that a server periodically
publish to users on the LAN the Multicast IP Addresses
that it can service. The IGMP query period defines the
time interval (in seconds) between each of these
queries for membership.
CDM-IP as Server:
IGMP max. response time
R
The IGMP max response time defines the time interval
(in seconds) that the CDM-IP should wait before it
assumes that no parties are interested in the content
published via an IGMP query. This option is expressed
in seconds, and the max response time that is
accepted by the CDM-IP is 25 seconds.
