Demonstration of packet-optic integrated transport system

We propose and experimentally demonstrate a packet optical integrated transport system. The proposed system supports packet transport layer features based on PBB-TE. The restoration time from a link failure is measured to be about 20 ms and 11.8 ms, respectively, in the packet transport layer and optical transport layer. The measured restoration time is much smaller than the 50 ms industry requirement for real-time services. The fast restoration time allows the proposed packet-optic integrated transport system to offer high availability and reliability which is a requirement for transport networks.
