IP NETWORK LOAD DISTRIBUTING METHOD, IP NETWORK, IP ROUTING DEVICE AND ROUTE SERVER

摘要

PROBLEM TO BE SOLVED: To realize dynamic load distribution of a network in an IP(internet protocol). SOLUTION: IP routing devices 10a, 10b and 10c transfer MIB(management information base) information regarding a load and MIB information regarding topology to a route server 20 by SNMP(simple network management protocol). The route sever 20 constructs all topology data bases of an IP network considering load information and feeds a calculated piece of topology information to all the IP routing devices 10a, 10b and 10c. As a result, the IP routing devices 10a, 10b and 10c create a routing table in consideration of a load state of the IP network and transfer an IP packet to the optimal route obtained by the routing table.
