ADDRESS TABLE MANAGEMENT METHOD AND ADDRESS TABLE MANAGEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress to a minimum the movement of an entry associated with the entry registration and deletion of IP addresses.

SOLUTION: The head and tail of a storage area for each block in an address table 13a registered with IP addresses are pointed by a pointer and the address of a unused entry caused by the deletion of an entry is registered in a stack memory 11b. When registering an IP address in the address table 13a, a processor 12 for device management detects the unused entry from the stack memory 11b and a network processor 14 performs the entry registration of this IP address in the unused area of the address table 13a.
