• A highly reliable and available network which automatically can restore itself from failures is an important concept for the future high capacity broadband networks.Selfhealing algorithm, restoring the failed VPs(Virtual Paths)in the backbone ATM networks, is an indispensable technique to meet these requirements.In this paper we propose a coordination-based restoring self-healing algorithm called C-TRUS, which meets different requirements of service classes of survivability by using a simple rerouting and capacity reserving protocols.The simulation results show that the proposed algorithm can restore VPs quickly and improve the restoration time in case of multifailures by using network resources very efficiently.Furthermore, C-TRUS outperforms the combination method in both restoration ratio and restoration time.In addition, the significant improvement of restoration ratio in the multi-failure scenario has been achieved.
