I have a capture and the network has redundancy built in. I and doing some captures for a client to help them determine why they are losing connection. in the capture, I see a Lott of window updates 740 I see duplicate acks 98 and I see TCP missed segment captured 98
My question is will a huge number of window updates cause a problem on the network? I know window updates are normal, but when there are a large number of updates, I am just wondering about that because I was ask what is the next step to improve the performance In short I don’t know can someone help thanks
There are no windows zero or windows full
No. Window updates are basically status messages about one node announcing a new window size in a TCP packet that contains no other new information. Depending on the application's communication profile it is quite common to have a lot of those. Zero Window and Window full are much more interesting for performance troubleshooting, but you say you've got none.
Without a trace it is kinda hard to help in troubleshooting connection loss issues, so all I can tell you is that you do not have to worry about Window updates in most cases.
