As Internet traffic is unexpectedly and rapidly growing, a single-link failure in networks can cause critical problems, especially,
survivability. Because it can lead to the failure of all paths traversing the failed link, and thus result in significant
loss of traffic. In this paper, we propose the end-to-end protection and restoration algorithm considering shared links and
then analyze it in terms of restoration time, blocking probability and bandwidth efficiency in the IP over WDM network.
