Mobility Support in Multi-Path TCP

摘要：

Mobile devices are emerging with multiple interfaces with diverse access technologies. Simultaneously use multiple interfaces can bring lots of benefits to users. However, current TCP fails to support to simultaneously use multiple interfaces. Thus MultiPath TCP is proposed to overcome the limitation. But MPTCP itself cannot provide mobility support, which may impose mobility restriction on mobile devices. We thus propose a mobility management scheme inside MPTCP protocol. We first propose several requirements for Multi-Path TCP mobility management and then present our solution. Our solution is based on the concept of ID/Locator separation. We use a permanent address and several temporary addresses to separate host identity and locations. By the cooperation of dynamic DNS and MPTCP, our solution has a good support in MPTCP mobility. Finally, we implement a real-world system of MPTCP with mobility support as a proof of feasibility of our approach.
