摘要： An apparatus for transferring data on a network. The apparatus includes a switch comprising a primary component for switching the data through the switch. The apparatus includes a secondary component for switching the data through the switch if the primary component fails. The apparatus includes a mechanism for counting the data that has been received, transmitted or dropped by the switch without including any redundancy in the counting of the data due to the primary component and secondary component both able to switch data through the switch. A method for transferring ATM cells on a network. The method includes the steps of switching the ATM cells with an ATM switch of the ATM network having a primary component for switching the cells and a secondary component for switching the cells if the primary component fails. Then there is the step of counting the cells that have been received, transmitted or dropped by the switch without including any redundancy in the counting if the cells due to the primary component and secondary component both able to switch the cells through the switch.

摘要： A timing distribution apparatus. The apparatus includes a source for producing a signal. The apparatus includes a first filter for removing jitter from the signal. The apparatus includes a second filter for removing wander from the signal separate and apart from the first filter. A method for producing a timing distribution signal. The method includes the steps of removing jitter from a signal with a first filter. Then there is the step of removing wander from the signal with a second filter separate and apart from the first filter.

摘要： An apparatus for storing a packet. The apparatus comprises a buffer in which packets are stored. The apparatus comprises a mechanism for determining an average buffer fill of the buffer, where the average buffer fill is an average fill state of the buffer. The determining mechanism is connected to the buffer. The apparatus comprises a mechanism for calculating a drop probability associated with the packet which identify is the probability the packet will be dropped from a the buffer. The apparatus comprises a mechanism for generating a random number. The apparatus comprises a mechanism for discarding the packet from the elements if the drop probability is greater in than the random number. A method for access control. The method comprises the steps of receiving a packet at an element having a buffer. Then there is the step of determining if an average buffer fill of the buffer in which the packet is to be stored is greater than a minimum threshold and less than a maximum threshold, where the average buffer fill is an average fill state of the buffer. Next there is the step of calculating a drop probability associated with the packet which identifies a probability the packet will be dropped from the element. Then there is the step of comparing the drop probably to a random number. Next there is the step of discarding the packet from the element if the drop probability is greater than the random number.
