Currently no communication service meets these data transport needs cost effectively. LightForce demonstrates the potential for transporting multiple gigibits of data with virtually no jitter by exploiting the capabilities of dymanic lightpath switching. It uses dynamic Layer-1 services and rapidly changing topologies that integrate multiple source and destination nodes, including remote nodes. Key technologies demonstrated include transparent mapping, lightpath control algorithms, resource allocation, arbitration among contending demands, extended FEC, error control, traffic stream quality, performance monitoring, and new protocols that exploit enhanced methods for low levels of BER. |
