<p><P>PROBLEM TO BE SOLVED: To provide a management method of a route table for which complicated design or BGP protocol expansion is not required, and a management server. <P>SOLUTION: A route table is received from a router 10 and a prefix is collected by a BGP receiver 2. Destination IP addresses of data packets relayed by the router 10 for a predetermined period are collected by a packet information receiver 3. Each destination IP address is allocated to the prefix and a use frequency as a destination of the prefix for a predetermined period is aggregated by a frequency aggregation part 4. A message to delete the prefix whose aggregated frequency is low is transmitted to the router 10 by a message transmitter 5. Further, a default route is set to the router 10 as another router for securing an arrival possibility of the prefix from which the next hop has been deleted. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
