Filed: 2002-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a soft multi-contract rate polishing which does not always handle a packet in the most preferable condition shown by any applicable bandwidth contract. SOLUTION: Many bandwidth contracts are prepared for a customer and different priorities are given to the contracts. Upon receipt of an incoming packet, a polishing engine selects the highest priority bandwidth contract to apply polishing data and determines if the incoming packet is in compliance with the selected bandwidth contract. If the incoming packet is in compliance with the selected bandwidth, the packet is accepted. If the incoming packet is not in compliance with the selected bandwidth contract and this contract has the lowest priority, the packet is discarded. If, on the contrary, the contract has not the lowest priory, the next highest priority bandwidth contract is examined to determine if the packet is to be admitted thereunder.
