Title:
REPEATER
Document Type and Number:
Japanese Patent JP3950754
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a repeater which shortens the time necessary for comparing received path information and a path information registered in a path information table.
SOLUTION: A hash value calculator 102 converts the path information, including a plurality of members into a single hash value. A path information cache section 104 stores path information already registered and its hash value, as a path information table. A path information comparator 103 compares the hash value of the received path information with the hash value stored in the path information cache section 104. A path information processor 105 additionally registers the received path information in the path information table, on the basis of a comparison result of the path information comparator 103.
