METHOD FOR TRANSCEIVING FORWARDING TABLE OF DISTRIBUTED ROUTER SYSTEM

摘要

PURPOSE: A method for transceiving a forwarding table of a distributed router system is provided to simultaneously transmit a forwarding table to all LP boards from a routing process board in a UDP/IP/broadcast method when driving an initial system, and to apply a TCP/IP/unicast method when transmitting the table to an LP board having an error and a newly inserted LP board, thereby reducing time for transmitting the forwarding table. CONSTITUTION: If a distributed router system starts operating(S301), a routing process board generates a forwarding table(S302) and configures the forwarding table by adding CRC values for both the forwarding table and size value information on the forwarding table(S303). The routing process board adds a UDP header to the forwarding table(S304), and adds an Ethernet header for broadcasting a destination address(S305). The routing process board transmits the forwarding table where the UDP header and the Ethernet header are included to an IPC board(S306). The IPC board checks the destination address of the received forwarding table, recognizes that the forwarding table is to be broadcasted, and broadcasts the forwarding table to all LP boards(S307).
