Mobile IPv6 protocols are a retrofit of mobility onto the next generation Internet(IPv6) protocols. Many of the original IPv6 protocols have inbuilt timing mechanisms which aim at ensuring fairness of access to media and signalling efficiency. The effect of these timers on Mobile IPv6 traffic has been found to signifcantly affect application traffic on these networks. One proposal to remove unnecessary timers in Neighbor Discovery is called Fast Router Advertisement (FastRA). This paper presents performance comparisons of FastRA with unmodified Neighbor Discovery in Mobile IPv6 environments.
