[Winpcap-users] rate limitation

[MARMONIER Cédric]

Hello, 

 

I do :

While(1){

            if (pcap_sendpacket(adhandle, buf, packetSizeInByte) != 0)

            {

                printf("\nError sending the packet: %s\n",
pcap_geterr(adhandle));

                return 3;

            }

}

ð  I send UDP multicast packets (size is 1514 Bytes)

 

With an 100Mb Ethernet Switch,  my PC send an 100Mb flow

But when I connect my PC to a Gigabit  Ethernet switch (D-LINK DGS-1008D),
my PC send a 45Mb flow : it isn’t the switch which drop packets but the
function sendpacket() which run slower (no packets are lost).

 

Do you know why ?

I think it isn’t the Ethernet flow control mechanism (802.3x) because with
wireshark I don’t capture PAUSE packets (wireshark can capture them ?)
