Abstract

   This document describes a novel mobility concept based on a
   combination of SCTP with Dynamic Address Reconfiguration extension
   and Reliable Server Pooling (RSerPool).

1.  Introduction

   An increasing amount of Internet devices is getting mobile.
   Therefore, there is a growing demand for software solutions allowing
   for a seamless handover of communication sessions between multiple
   networks, e.g. to allow for a laptop or PDA to use a fast Ethernet
   connection when available, hand over to a WLAN when moving and hand
   over again to UMTS when the WLAN becomes unreachable - without
   interrupting the running communication sessions.

   Mobility handling is a deficiency of the common IP-based networks.
   Most of the available solutions are based on the network layer.  The
   disadvantage of such solutions is that fundamental changes in the
   network infrastructure are needed.  Therefore, we propose a new
   solution based on the upper layers to overcome these disadvantages.
   In this document, we present our mobility solution based on the SCTP
   protocol with Dynamic Address Reconfiguration extension and Reliable
   Server Pooling (RSerPool).

2.  Existing Mobility Solutions

2.1.  Mobile IP and Mobile IPv6

   In the concept of Mobile IP [RFC5944] every node must register to a
   Home-Agent (HA) in its own home network.  Then, the nodes are
   reachable under their home addresses managed by the HA.  When a node
   leaves its home network, it must also register at a Foreign Agent
   (FA) in the new network.  After that, a tunnel is established between
   the HA and the FA.  Any traffic to the mobile node is then tunnelled
   by its HA to the FA and forwarded by the FA to the node itself.
