Abstract:
1. A cell disposal avoidance system in a buffer, said buffer including category buffers classified by category in an ATM switch, said category buffers each for storing a cell, said buffer reading out said cell, said system comprising: a weight representing a priority that determines the reading rate for each of said category buffers; a reader for laying out allocation in a time division mode according to said priority, said allocation being read out of each of said category buffers when a cell in a buffer is read out, and reading out said allocation in a round-robin format; a detector for detecting cell disposal of said buffer; a controller for changing to a higher weight a weight of the priority in a buffer in a cell disposal state detected by said detector; an informer for informing a maintenance terminal of the fact that said buffer in a cell disposal state has stopped its cell disposal; and a first resetting unit for resetting a weight representing the priority of said buffer in the cell disposal state by commands input by said maintenance terminal.
