Fast, Secure Failover for IP

We describe a mechanism for fast, secure failover for IP. The mechanism is invisible to end-systems: sessions are maintained during failover. Our novel approach is to model the failover as a mobility problem, and use a mobility solution in order to implement change in connectivity. Our system is based on the Identity Locator Network Protocol (ILNP), an Experimental IRTF protocol which is realised as superset of IPv6. Our empirical results from a test bed emulation show that there is almost zero gratuitous loss during failover.
