I have two machines connected to the same LAN and multicasting UDP streams at rate of about 30Mbps. Analyzers often show packet losses on one machine, but never on another.
What could be the reasons for packet losses on particular machine?
I use ubuntu OS. Multicasts passes through router. But when I multicast in LAN with switch, it works fine with zero loss. Packet looses only when router added. Both machines has same hardware, same every piece of hardware.
Multicast from other machine doesn't loose any packets even through router.
