    The handoff latency of many new access technologies such as wireless LAN devices is very large, on the order of hundreds of milliseconds. This results in significant performance degradation during handoff. In this document we propose an approach that uses multiple transceivers of the same access type to enable...

    According to IPv6 standards, when there is a router solicitation, router advertisements will be sent after a random delay of up to 500ms. This degrades the performance of mobile IP handoffs. In this document we propose a scheme that enable routers to auto-configure this delay. Specifically it results in a zero delay...
