    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: 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.
