Hi H P,
It seems that you have made some progress. I do not know your simulation configuration. As I know the default length of IFQ is 50 packets. If you have not change it, you can change it to a larger value and be sure that your traffic source sends the packets slower than the MAC layer does. Best regards.

I tried to do a fragmentation at the link layer, and I found that as more and more packets are generated, some packets are lost in the IFQ. Has anyone experienced this before? Is there a memory limitation of ns? I did the fragmentation as follows : Many copies of each LL frame is generated and sent down to MAC. At the receiving MAC, these packets are collected to form a frame, and then sent to the Link Layer. Thanks for any reply. |
