On the use of failure detection and recovery mechanism for network failure

Future of internet is predicted to be multi-interfaced. Site Multi-homing by IPv6 Intermediation-Shim6 is a proposal presented in IETF to provide multi-homing support in IPv6 based networks. Although initially it was intended for static networks but recently it has been tested to provide end host mobility. Failure detection and recovery in Shim6 is performed through REAchability (REAP) Protocol. This protocol shows significant improvements over MIPv6. Recently, due to inherited flaws in MIPv6, more protocols and combination of protocols are implemented and also been tested. In this contribution we implemented LinShim6 test bed and observed the behavior of switching locators under the use of REAP. This work is done by keeping in view that how the QoS factors are affected when REAP is used for network failure and recovery in home environment. REAP is activated when the communication path is failed. Sometimes host has access to multiple ISPs through its multiple locators. If one locator fails, communication is shifted to another locator. In Shim6 context it is called locator change. We experimentally validated the working of LinShim6 and condition of network considering packet loss, jitter, throughput and data transferred. In addition we propose that if an intelligent approach is used, switching delay can be reduced. We called this Shim6 Assisted Mobility Scheme (SAMS). Some initial experimental results are also presented in this work.
