Our organisation's desktop computers have been performing not satisfactorily during their accessing of network resources. Out of suspicion, I perform a TCP retransmission statistics. Below picture is what I got.

I saw that the retransmissions (blue series) are happening in a regular pattern. Is this normal? TCP retransmission graph

Some TCP retransmission is normal, but this looks excessive. Looks like you have packet loss and will have to "walk the line" and check physical connections, cabling, speed/duplex mismatches. Check out the link below.
