An asynchronous mode transfer (ATM) switch conducting switching based upon the calculation of weights for entries corresponding to cells in an input queue to achieve a high throughput rate which avoids head of line blocking. The switch includes a cell scheduler driven by the iterative resolution of a...http://www.google.com/patents/US5923656?utm_source=gb-gplus-sharePatent US5923656 - Scalable broad band input-queued ATM switch including weight driven cell scheduler
