Title: Congestion control method
Inventor: TANIGUCHI HIROKI
IPC: H04Q3/00
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide the congestion control method in which data abort on the occurrence of congestion is suppressed and re-transmission control between transmission reception terminal equipments is prevented to the utmost. SOLUTION: In the congestion control method conducted by nodes N1-N4 which have a data flow monitor function monitoring a data flow flowing through a transmission path is a preset specified value or below and a self- routing function selecting a data transmission path automonously. When a node predicts it that its own node may reach a congestion state by using the data flow monitor function, the node sends the data received newly back to a pre-stage node being the data supply source and inhibits the reception of new data from the pre-stage node. When the congestion state of its own node is relieved by the detection of the data flow monitor function, the node releases the inhibited input of data from the pre-stage node being the data supply source.

Filed: 1988-08-31
Abstract: PURPOSE:To assure high coupling efficiency, wide band characteristic and low noise characteristic by providing a spherical lens part to the tip of an optical fiber and condensing propagated light through the reflecting film on the surface to a photodetector. CONSTITUTION:The spherical lens 2 is formed to the end of the optical fiber 1 by deviating a center 3 with respect to the optical axis 4. The reflecting film 5 is provided on the surface of this lens. The light propagated in the optical fiber 1 is introduced through the reflecting film 5 to the photodetecting surface 6 of the photodetector 7 by which the light is subjected to opto-electric conversion. The reflecting mirror 5 acts as a concave mirror and the spherical lens 2 acts as a convex lens in such a manner and, therefore, the light is condensed to the min. spot at the proper point of the photodetecting surface 6 parallel with the optical fiber axis 4. The high optical coupling efficiency is thus obtd. even with the small photodetecting surface 6. Since the photodetecting surface 6 can be formed in parallel with the optical axis of the optical fiber 1, the miniaturization of the device is possible.
