Abstract :
Describes the design and implementation of a set of tools, called MobileChannel, for use with the Isis system. A simple scheme to support user mobility-switching a control point between replicated servers-provides a uniform mechanism to handle both client migrations and server failures. The hands-off mechanism is simplified by integrating a FIFO channel implementation into the server replication mechanism. Our scheme provides a simple abstraction of migration, practically eliminates hands-off protocols, provides fault tolerance, and is implemented within the existing group communication mechanisms of Isis
