摘要： A method and apparatus for making assignment of virtual path and virtual channel identifiers under a "free status" in an asynchronous transfer mode switching system, at high speed, without delaying a call processing speed of a call processing circuit. The method for assigning virtual path and virtual channel identifiers placed in a cell header area includes the step for setting predetermined header values in a memory having a FIFO function; the step for checking a storage state of the memory when a connection requirement of a call occurs; the step for transferring stored header values to interface circuits corresponding to the connection requirement after the stored header values are read from the memory when the memory is not in an empty state; and the step for storing in the memory the header values used for the call required for a release when a releasing requirement of a call occurs.

摘要： In allocating bandwidth using a Resilient Packet Ring (RPR) fairness mechanism in a node connected to an RPR network, when congestion occurs, an amount of traffic that the node has transmitted to a ring during one aging interval is stored together with its own identifier in a fairness message as a fairness transmission rate to be advertised to its own upstream nodes. The amount of traffic transmitted from the upstream node during the aging interval is measured and stored. When the congestion has been solved, an available bandwidth is calculated with reference to the fairness transmission rate and the amount of traffic transmitted from the upstream nodes, and the fairness transmission rate is calculated to fairly allocate the available bandwidth to the upstream nodes so that the fairness transmission rate is transmitted to the upstream nodes.

摘要： An Internet Protocol address look-up method for looking up an Internet Protocol address of an Internet Protocol packet in order to forward the Internet Protocol packet uses a ternary content addressable memory (CAM) which has routing entries, each including a pair of data strings having a prefix of an Internet Protocol address and a mask string representing a length of the prefix, which compares a search key as a destination address of the Internet Protocol packet to be forwarded with the routing entries, which sets a match line of a matching routing entry, and which outputs a mask string of the matching routing entry. The method comprises the steps of: comparing prefix lengths of mask strings outputted in correspondence to set match lines when at least one match line is set in the ternary content addressable memory (CAM); and determining, as a longest prefix matching (LPM) entry, a routing entry corresponding to a mask string having the longest prefix length.
