The Pgm_Source_Admit_High option specifies the maximum number of multicast messages held on the admit queue before RTgms stops queuing additional messages. The admit queue is a queue of multicast messages waiting to be transmitted by RTgms using PGM. The messages in the queue might have been generated by RTgms or in response to a NAK.
If RTgms is stopped from sending data over PGM, SmartSockets buffering is used until RTgms can send messages over PGM again. When the number of messages waiting to be sent is greater than the value you specified for Pgm_Source_Admit_High, RTgms is flow controlled until the number of waiting messages drops below the value you specified for Pgm_Source_Admit_Low.
If you set a value too high for Pgm_Source_Admit_High, it can waste memory in RTgms. Too small a value can waste CPU time by causing RTgms to be stopped too often.
