A Simple Solution to Scale-Free Internet Host Mobility

We introduce a simple solution for the support of host mobility in the Internet called DIME (Dynamic Internet Mobility for End-Systems). DIME is based on dynamic address translation between the transport and network layers of end hosts, combined with a new out-of-band protocol that updates host-address bindings between communicating hosts opportunistically. It does not require modifications to the end-host operating systems, end-user applications, existing communication protocols or hardware, or the domain name system and any host-identifier namespace. A number of experiments based on a Linux daemon implementation of DIME are used to show that DIME is deployable on a wide range of hardware, and that it outperforms existing mobility proposals such as MIPv6 and HIP across a wide range of performance metrics

End-to-end mobility for the internet using ILNP

This work was partially funded by the Government of Thailand through a PhD scholarship for Dr Phoomikiattisak.As the use of mobile devices and methods of wireless connectivity continue to increase, seamless mobility becomes more desirable and important. The current IETF Mobile IP standard relies on additional network entities for mobility management, can have poor performance, and has seen little deployment in real networks. We present a host-based mobility solution with a true end-to-end architecture using the Identifier-Locator Network Protocol (ILNP). We show how the TCP code in the Linux kernel can be extended allowing legacy TCP applications that use the standard C sockets API to operate over ILNP without requiring changes or recompilation. Our direct testbed performance comparison shows that ILNP provides better host mobility support than Mobile IPv6 in terms of session continuity, packet loss, and handoff delay for TCP.Publisher PDFPeer reviewe

A Deployable Identifier-Locator Split Architecture

Despite the vast set of prior work on identifier-locator split architectures, no one approach has seen much success, adoption, or deployment in the Internet at large. We identify the key set of challenges that have inhibited the deployment of these proposals to date, and introduce the Dynamic Internet Mobility for End-Systems (DIME) approach. DIME is based on dynamic address translation between the transport and network layers of end hosts, combined with a simple out-of-band protocol that updates host-address bindings as needed. DIME is the first and only proposal that achieves a clean identifier-locator split without  requiring modifications to the end-host OS or applications; modifications to existing network protocols, security mechanisms, or hardware; or  a new host-identifier namespace. We  evaluate a Linux daemon implementation of DIME, and show that it i outperforms existing mobility proposals such as mobile IP (MIPv6), multipath TCP (MPTCP), and the Host Identity Protocol  (HIP) across a wide range of performance metrics
