摘要： A distributed router able to reduce occurrence of ping-pong of data and information packets within the architecture of the distributed router constructed with a main processor, a plurality of line connection units and a switching unit, is disclosed. The main processor manages a routing table, updates the routing table, and broadcasts the changes in routing information that are received. The switching unit switches packets either to the main processor or to the respective line connection units. A plurality of forwarding tables are positioned in different corresponding ones of the plurality of line connection units, to copy, store and manage a part of the routing table. A plurality of forwarding processors are positioned in different corresponding ones of the plurality of line connection units, to transmit each packet to an output port, to determine whether the output port of a packet received from the switching unit is connected to either an external router or the switching unit, and to transmit each packet to the external router when the output port is connected to the external router, and discard any packet when the output port is connected to the switching unit.

摘要： In an apparatus for distributively processing a border gateway protocol (BGP) and a method thereof, a central processing unit does not process all tasks for processing the BGP, and distributed BGP processing units are formed in the central processing unit so that each distributed BGP processing unit manages TCP sessions with external BGP routers belonging to the distributed BGP processing unit. Information is internally transmitted in the distributed BGP processing units using a multicast scheme and a broadcast scheme so that loads can be distributed. The apparatus comprises a number of BGP routers existing externally, a BGP router corresponding to a server, and a number of distributed BGP processing units in the BGP router. The distributed BGP processing units only manage the BGP routers connected directly to each distributed BGP processing unit in accordance with an operator's policy. When each distributed BGP processing unit receives update information from the external BGP routers connected directly to it, it performs a filtering function for deciding whether or not a route is to be transmitted in accordance with an INPUT policy, a route-map function for a transmission path mapping, and a damping function for deciding whether or not the update information is to be transmitted in accordance with a threshold value when flapping occurs.
