Unrelated packets in TCP communication capturing results

Question

I am using Wireshark to capture TCP communication packets in my experiment (using Mininet Simulation). The experiment involves a client (10.0.0.2) who requests HTTP page from the server (10.0.0.1). The following screenshot shows the capturing number 75 when the client sends HTTP GET and capturing number 89 when the server responds. Between them, I don't know what these packets are. Are they important in terms of TCP communication?

Thank you

depends on what you are analyzing. If you are concerned with the HTTP conversation then right click on one of the http rows and click- follow TCP stream. This lets you see entire http session. If you are having issues with the underlying TCP connection then those in-between rows become important.

Can I ask what is the purpose of PDU packet? Is it another meaning of saying (packet payload) ? – Frank Dec 12 '16 at 20:04
I have had the same question in the past and have run across this post from wireshark: https://www.wireshark.org/lists/wireshark-users/200805/msg00206.html – E LaRoche Dec 12 '16 at 20:28
