Latest Patents

One of Obana's latest inventions is the "Polling Period Controlling Apparatus." This apparatus is designed to poll with a period that can trace temporal variations of management information values of a managed unit. It features a polling period calculator that decomposes a sequence of management information values stored in sequence memory into the sum of sinusoids with different frequencies. By finding the maximum frequency, the apparatus determines the polling period from an inverse of two times the largest frequency. A central controller then compares the required bandwidth specified by the polling period with the network management bandwidth. If the required bandwidth is smaller, it obtains the management information value using the polling period. Conversely, if the required bandwidth is greater, the central controller uses the polling period determined from the network management bandwidth. The management information value obtained is saved in the sequence memory while the oldest group of management data is eliminated.
