These days, mobile phones often have more than one network interfaces. For example smartphones and tablet PCs can access the internet either from connecting via WiFi or via a mobile network. Devices that are simultaneously connected in different networks are called Multihomed. The ability to use many addresses (whether that is in the same or in many interfaces) makes internet access possible and with bigger tolerance towards errors that might occur. Especially in the case of mobile terminals where the possibility of a sudden internet disconnection is bigger. The usage of multiple paths simultaneously is called Multipath (routing). Recently, a work group from IETF was created, so they could determine a multipath protocol in the transport layer called Multi-path TCP (MPTCP). MPTCP is an extension of the transmission control protocol (TCP), which is the most often used transfer protocol on the internet, aiming to handle multiple hyperlinks on different paths between two ends. In this thesis we study the MPTCP protocol, and simulate it using the NS-3 simulator. For simulating different scenarios and exporting numerical results and conclusion we use NS3.
