Mptcp is a tool for raw packets manipulation that allows a large number of options. Its primary purpose is to diagnose and test several scenarios that involving the use of the types of TCP/IP packets. It is able to send certain types of packets to any specific target and manipulate its various fields at runtime. These headers can be modified in its structure as the the Source/Destination IP address and Source/Destination MAC address. Many types of network based attacks (packet attacks) also are treated by MpTcp.
