See my other post for an introduction of MPTCP. Even though it is an extension of TCP, the changes are deep enough that it could be considered a new protocol. How to install MPTCP on linux
Follow mptcpanalyzer’s README instructions to install the software.
First we need some pcaps, you can either capture some traffic yourself, or download some PCAPs from either the wireshark wiki or mptcpanalyzer examples.
Start mptcpanalyzer then load the pcap with:
load-pcap examples/client_2_filtered.pcapnghelp shows you the available commands.
To inspect at high level the pcap, run:
list-tcpto list tcp connections.
Similarly you can list mptcp-sessions:
examples/client_2_filtered.pcapng> list-mptcp
