Abstract
The OBLSR protection architecture using the ONPE was introduced into the IP network. The all-optical protection effectively achieved a faster protection of IP packets than OSPF-based IP layer protection. We demonstrated the protection time for IP layer to be less than 21 milliseconds in a 500 km bi-directional ring network by using the OBLSR protection and the proper guard time of IP routers.
