Abstract:
1. An IP processor provided for ATM switches connected to an IP network, said IP processor comprising: a line interface unit for interfacing with said ATM switch; an IP packet buffer unit for storing an IP packet from said line interface unit, and sending out the IP packet after address resolution to said line interface unit; and an IP address resolution unit that responds to address resolution request from said IP packet buffer unit, and returns the destination address information after address resolution; wherein said IP packet buffer unit includes an inter-IP processor transfer analyzing unit and an IP processor table, and further sends out, when the inter-IP processor transfer analyzing unit determines the destination IP processor based on information obtained from the IP processor table, said stored IP packet to the destination IP processor via a direct connection line fixedly routed between a plurality of IP processors without mediation by said IP network and ATM switches.
