The Internet is supported by long haul WDM core networks. Reliability is a huge concern in WDM core networks since service disruption would carry significant revenue, reputation and prospect loss. In ensuring reliability to network services, two means of protection scheme are usually used in WDM core networks; dedicated path protection and shared path protection. A comprehensive comparison of dedicated and shared path protection is discussed in this study. Availability concerned path protection implemented in the study will be based on random dynamic arrival traffic with adaptive routing method. The comparison will be based on several quality benchmarks such as availability satisfaction ratio, blocking probability, link utilization, provisioning complexity and network utilization.
