Abstract: A first set of instructions associated with an egress of a datagram may be determined, the first set of instructions identifying a first subset of a second set of instructions, the first subset including multiple individual network identifiers identifying which network portion to transmit a replication of the datagram. Which one of the multiple individual network identifiers corresponds to the datagram may be determined from the first subset of the second set of instructions and may be based on the egress of the datagram, wherein each network identifier corresponds to a different egress. The replication of the datagram may be provided to the egress of the determined network identifier for transmission to the network portion as identified by the determined network identifier corresponding to the datagram.

Abstract: A method and a system for allocating memory in a memory buffer that is part of a data distribution device. Generally, the allocation of memory is for the purpose of storing datagrams. The method allocates memory in the buffer based, at least partially, on how ingress ports that are operably connected to the memory buffer have previously used the buffer to store datagrams. The system typically includes one or more detectors that monitor how various ingresses into the data distribution device are using and have used the memory buffer.

Abstract: A method and system for processing the signals of a touch panel are provided. Therein, the capacitive values of each sensor on the touch panel are successively taken during a period of time. Then, the average capacitive value of each sensor is calculated for computing estimated touch point coordinates. The distance between each two sets of such coordinates sensed respectively at two sensing time points is calculated. If a distance thus calculated is less than a predetermined distance, the two sets of estimated touch point coordinates corresponding to the distance are defined as valid touch point coordinates. If a series of estimated touch point coordinates are successively defined as valid touch point coordinates for a predetermined number of times, the touch point corresponding to each set of valid touch point coordinates in the series is defined as a valid touch point. Thus, the precision of touch point determination is enhanced.
