Feature Changes
Configuring the MMEDEMUX
Previous Behavior: MMEDEMUX had insufficient waiting time to distribute the incoming traffic to the associated
MMEMGRs because all MMEMGRs were not up and running on startup of the box.
MMEMGRs because all MMEMGRs were not up and running on startup of the box.
New Behavior: A new CLI command is introduced in the MMEDEMUX system, which allows operators to configure
the percentage of MMEMGRs to be associated, and the waiting time to process the incoming traffic. The MMEDEMUX
distributes the incoming traffic to the associated MMEMGRs based on the percentage value and wait time configured in
this command.
the percentage of MMEMGRs to be associated, and the waiting time to process the incoming traffic. The MMEDEMUX
distributes the incoming traffic to the associated MMEMGRs based on the percentage value and wait time configured in
this command.
Customer Impact: The new configuration provides the following:
By default, MME waits for ten minutes to check if 90% of the MMEMGRs have started.
MMEDEMUX allows users to configure the waiting time up to 3600 seconds.
MMEDEMUX allows users to configure from 1 to 100% of the available MMEMGRs.
