Abstract: PURPOSE: A transmit control method in a network structure based on dual rings is provided to calculate an equitable transmit rate of nodes based on the number of packets of a transmit buffer in each node, thereby remarkably improving link usage efficiency and equitable properties. CONSTITUTION: A system confirms whether nodes are congested(500). If so, the system confirms whether a received equitable transmit rate is null and the number of packets of a transmit buffer is smaller than a threshold value(501). If not, a lower node confirms a value of the received equitable transmit rate and compares whether a transmit rate of the nodes is smaller than the received equitable transmit rate(503). If so, the system transmits a transmit rate of a current node to an upper node(504). If the transmit rate is not smaller, the system controls the transmit rate of the current node and transmits the equitable transmit rate of the lower node to the upper node(505).

Abstract: PURPOSE: A node system, a dual ring communication system using the same and its communicating method are provided to effectively control congestion occurring as each node transmits packets. CONSTITUTION: If bandwidth occupied by packets which a node 4(104) transfers is too much to transmit packets as many as desired, congestion information packets are transferred in a direction opposite to a data packet flow(S1). A node 3(103), which has been contributed to congestion, adds its congestion-related information to the congestion information packets transferred from the node 4(104) and transfers it to a node 2(102)(S2). The node 2(102), which has not been contributed to congestion, transfers the received congestion information packets to a node 1(101)(S3). The node 1(101), which has been contributed to congestion, allocates bands on the basis of its congestion-related information and the received information on the congestion-related packets, sends corresponding result carried on band allocation packets in the same direction as the data packet flow(S4). The band allocation packets are transferred to the congestion-occurred nodes(103,104) and the nodes(103,104) set the bandwidths allocated to them as maximum transmission bandwidths, and lower their packet transmission rate(S5,S6).

Abstract: 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).

Abstract: A router for supporting differentiated qualities of service (QoS), and a fast Internet protocol (IP) packet classification method performed in the router, are provided. The router hierarchically divides a memory having flow tables into a fast internal cache memory and an external typical memory. The internal cache memory stores recently searched table entries. The router preferentially searches the flow tables of the internal cache memory. Only when the internal cache memory searching fails, the flow tables of the external memory are searched. Consequently, the frequency of interactions between a packet classifier and the external memory decreases to improve the speed of packet classification.
