摘要： The present invention provides an optical signal quality selection system for optimizing the quality of information transmission. The system splits an incoming optical signal into two equal signals. The split signals are evaluated in optical performance monitors, transmitting an electrical output message to a signal selector relating to the quality of the respective signal. A second electrical message is sent from the optical performance generator to an alarm indicator signal generator, which sends an optical signal to the signal selector to drop the one of the split signals and transmit the non-dropped split signal. An unequipped optical signal from an optical idle signal generator is triggered if no active optical signal is being transmitted.

摘要： In a novel restoration management method and system, the restoration messages are treated in two ways simultaneously so as to avoid delay in transmitting to a next node. In particular, a router alert bit is attached to each restoration message at an edge of the restoration network, which is read by a Label Switched Router so as to identify the restoration message as such. Then the restoration message is duplicated. The original one is directly forwarded to the next node through the shim player so as to avoid any delay. The duplicated one is sent to the application layer at the node for being processed there.
