## Abstract
When a router fails in IP-over-EON, some traffics are affected. Each affected traffic attempts to be restored through the best alternate path among alternate paths offered. Some conventional routing schemes are commonly used to solve problems in IP over optical networks, namely k-shortest paths (KSP), hop count (HC), and link-disjoint (LD). The three schemes are fixed-alternate routing (FAR) schemes. However, the alternate paths it generates cannot adjust to the current network conditions due to a router outage. Therefore, this study proposes an adaptive routing, i.e., adaptive lightpath reconfiguration paths (ALRP) routing. ALRP routing explores the number of paths between the source and destination pairs for each affected traffic and then selects the best alternate paths by maximizing the utilization of unaffected lightpaths. The goal is to minimize costs relate to the number of lightpath reconfiguration and additional power consumption due to the recovery of affected traffic. Based on simulations conducted using two network topologies, namely seven-node topology and NSFNET topology, it was found that the proposed ALRP routing produced better results compared to the three conventional routing schemes in minimizing the addition of both costs.
