Putting SHIM6 into practice

SHIM6 is a host-centric solution for multihoming in IPv6 networks. It is fully implemented in hosts and does not affect the Internet routing system. We present the results of experiments with SHIM6 in the lab and over the Internet. The aim is to evaluate the behaviour of SHIM6 in case of link failure. We tried two transport protocols, TCP and DCCP, measuring traffic and recovery time, two important performance metrics. In addition, the experiments revealed some operational issues which must be addressed before SHIM6 can be deployed world-wide.
