[lwip-users] Request to post the message under category "UDP bradcast frames filtering"

[Pranita . Gujarathi]

Hi,

 

I want to post below message to all lwip users mailing list.

 

Message is as below:

 

We are receiving 4 UDP frames (broadcast) at 2 ms interval but these frames are not meant for us. We have discarded these broadcast frames in udp_input() function.

These frames are received at repetitive interval like; 4 frames at 2ms interval each, then after 100 ms again 4 frames and repeated.

UDP broadcast frames which are meant for us are received at 7-8 ms interval time. But due to above repetitive behaviour, performance is degraded.

Can we filter out these unwanted broadcast UDP frames at earlier level? Is there any other way not to degrade the performance?

 

               

Regards,

Pranita
