摘要： A node structure of a multiway search tree can accelerates a search speed by making a key, a key pointer and a node pointer coincident with the size of a cache line through the use of only one pointer written on a node regardless of the number of keys used in the node and, thereafter, reduce the main memory capacity, a search method using the node structure and a computer readable recording medium in which a program implementing the search method is recorded. The method for generating nodes of a multiway search tree includes the steps of: a) assigning at least one key to each of the nodes; and b) assigning pointer information so that related information written on the node is accommodated in a cache line regardless a number of keys.

摘要： Disclosed is a broadcasting and communication combining system based on an Ethernet and a method thereof for providing an Internet service and a multi-channel broadcasting service. The broadcasting and communication combining system and method based on an Ethernet uses Ethernet broadcasting frames on a data communication network to provide a wideband Internet service and a multi-channel digital broadcasting service. To support both Internet and broadcasting with one wavelength, the broadcasting traffic is converted to Ethernet data and multiplexed, and the multiplexed broadcasting traffic comprising the same band (one wavelength) of Internet data is transferred to a subscriber network. The subscriber terminal unit discriminates between Internet traffic and broadcasting traffic and outputs the Internet traffic and the broadcasting traffic to the final receiver.

摘要： A ring selection method for a dual ring network to perform node-to-node packet transmission. A transmission node transmits a reception node address request message for packet transmission to all nodes, and updates a routing table using information on a short path transferred from the reception node. The information on inter-node hop numbers included in the routing table is used to select a ring having the lowest hop number between the reception nodes It is then determined whether the selected ring is wrapped, and if the ring is not wrapped, comparing its usage rate and hop number to the reception node with reference values based on a ring selection algorithm; and if the ring is suitable based on the reference values, selecting the ring for packet transmission.

摘要： The present invention relates to a method for supporting Internet Protocol version 6 (IPv6) in a wireless communication system. According to an exemplary embodiment of the present invention, a wireless communication system consists of an access router, a bridge, and a base station. The access router allocates a common network prefix to all subscriber stations served by it. When receiving IP multicast data destined for all nodes on the same link, the access router forwards the data back to the bridge. The bridge transmits IP multicast data with reference to an identification cache table (ICT) which includes MAC addresses of each subscriber stations, identifiers for point-to-point connections between the bridge and base station, IPv6 addresses of each subscriber station and valid flags for the IPv6 addresses. The base station provides point-to-point connections to both the bridge and each of subscriber stations.
