TCP Retransmission in Information tab of Ethereal


Hi
I am working on socket programming. i am using ethereal to check the network latency. can anyone tell me what condition occurs when Information column of the display window shows TCP Retransmission.
Is it a chat/warn?
How to eliminate TCP Retransmission?
i also get checksum error but the data send at server and data received at client are same i.e. no data packet is lost... when and why does this checksum error occur?
Thanks

A retransmission occurs when the remote end does not Ack the packet in sufficient time, or at all.

Checksum errors are likely occurring because your NIC has TCP checksum offloading enabled. Disable the NIC from performing the checksum itself while you are packet capturing.
