A Soft, Prioritised Early Packet Discard System is provided, which is suitable for satellite onboard switching and very-high-speed terrestrial switching applications. The system counts the number of newly arriving packets, calculates and regularly updates an average queue size, which is used in setting a packet-count threshold via a descending staircase function. When the number of newly arriving packets reaches the packet-count threshold and when the average queue size reaches or exceeds the congestion threshold; a packet is discarded and the packet-counter is reset to zero. The counting of packets is halted while the average queue size remains below the congestion threshold. The regular dropping of packets allows simplified hardware implementations. In calculating the average queue size, a progressively higher exponential queue-length averaging parameter is used for higher instantaneous queue length, to provide faster reaction to congestion situations. The averaging parameters and packet-count thresholds are implemented using lookup tables. A priority-based method is incorporated to better match the Quality of Service requirements associated with a service class.

An amorphous silicon layer is deposited on a glass substrate via an underlayer insulating film, and further a light-emitting layer is inserted between the glass substrate and the underlayer insulating film in a partial region on the glass substrate. To measure light intensity distribution of laser light applied to the amorphous silicon layer, the laser light is applied to the light-emitting layer from the surface of a substrate to be treated. The light intensity distribution of the light emitted from the light-emitting layer is two-dimensionally imaged using an optical image pickup system from the back surface of the substrate to be treated, and measured using an image pickup device. The light intensity distribution of the laser light in the face to be treated is obtained from the light intensity distribution of the emission measured in this manner.
