QoS API for packet scheduler

From: Angie on 4 Apr 2008 17:28 All, I find one problem with the Netmeeting running on the WAN adapter when the packet scheduler is enabled. The problem I found as follows. During the conversation session(voice data is transmiting), if I send a ping packet to the peer, the ICMP echo packets are blocked by the packet scheduler when they are received. By running theWireShark to capture the packets, I can see the ICMP echo packets there. However, ping test cannot go througth. If I disable the packet scheduler, the problem is solved. Is there anyone who knows what QoS API in windws that I can call to control the packet scheduler programatically?

Are you sure that packet scheduler blocks any packets on receiving side? AFAIK it deals only on the sending direction. --PA > If I disable the packet scheduler, the problem is solved. > > Is there anyone who knows what QoS API in windws that I can call to > control the packet scheduler programatically? > > >
From: Angie on 4 Apr 2008 18:33 Yes, the ICMP echo packets (receiving side) are blocked becasue I could see them from the WireShark when I captured the packets from the PPP adapter. In addition, I captured the packets from the peer and ICMP(request, echo) packets could be found there.

From: Angie on 4 Apr 2008 21:52 I am reading the Traffic Control API. I am not sure that those APIs can help or not.
