I have experiencing a UDP Multicast packet drop with Intel I340-T4 quad port network adapter.
I believe this is caused by open/close Multicast receiving socket on the same physical network port.
Here is my setup:
OS: Windows Server 2003
I340-T4 Driver version 126.96.36.199
Multicast receiving socket which suffer dropped MCast packet:
- MCast IP: 188.8.131.52
- Port: 12345
- Interface: 192.168.8.11
- receving a 14MBit source
- experience packet drop once every 1 min
Open and closing socket:
open a socket, listen to a source for 2 second, then close it. Repeat this cycle every 4 second.
- Port 12345
- receive a 14MBit source
Socket 2 - 7
- MCast IP: 184.108.40.206
- Port 25000
- no source
- MCast IP: 220.127.116.11
Receive the same MCast source, from the same NIC card, but different physical port.
NO packet drop.
- Interface: 192.168.9.11
So far we believe it's likely a driver problem.
Can you confirm it?
