Abstract

In this paper we will analyze the many components of a L3 hand-off and will introduce a novel algorithm for reducing the L3 hand-off time. We will introduce the concept of Temporary IP address (TEMPIP) as a way to resume communication immediately after the handoff while waiting for the DHCP server to assign us a new IP address (NEWIP). We will show how, with our approach, it is possible to reduce the L3 handoff latency to values that in some cases allow us to have seamless VoIP sessions.
