Embodiment Construction

[0053] figure 1 is a block diagram of a distributed router.

[0054] refer to figure 1 , the distributed router 100 includes a plurality of line cards (LCs) 111 to 116 , a switch fabric 130 , and a routing processor 140 having a routing table 141 .

[0055] The LCs 111 to 116 include forwarding tables (FT) 121 to 126, respectively.

[0056] The routing processor 140 handles routing for external peer distributed routers connected via LCs 111 to 116, respectively.

[0057] That is, when an external peer-to-peer distributed router is connected through a network, the routing processor 140 processes ingress information transmitted from the respective external peer-to-peer distributed router according to a routing protocol, thereby generating / managing the routing table 141 .

[0058] The routing protocol processed in the routing processor 140 may be Routing Information Protocol (RIP), Open Shortest Path First (OSPF) protocol, Border Gateway Protocol (BGP), or the like. LC111 to ...

Abstract

A distributed router includes: a number of ports adapted to be connected to peers via a network, to receive messages containing packets and entry information from the peers, and to output the packets for transmission to destinations; a switching fabric adapted to switch the packets received through the respective ports to output the packets to corresponding output ports; and at least one line card adapted to extract the entry information of the peers from the messages received via the input ports, to process the entry information according to a preset routing protocol to determine a best route, and to output the packets received from the peers through the corresponding output ports according to the best route.

Description

technical field [0001] The present invention relates to a distributed router, in particular to a distributed router and its routing method and a program storage device readable by a machine, which truly realizes the instruction program executable by the machine so as to execute the routing method, A routing protocol distributed in the distributed router is processed therein. Background technique [0002] A router generally consists of four components: an input port, an output port, a switching fabric, and a routing processor. [0003] The input port is a point of contact with the physical and receives packets from the outside. A switch fabric provides an internal connection between an input port and an output port. [0004] The output port stores the data packet and executes the planning scheme to send the data packet to an output link. [0005] The routing processor processes a routing protocol and generates a forwarding table for forwarding packets. [0006] When a rou...
