Abstract: A forwarding information management method and a router system using the method are provided to enable the distributive router system to regularly manage control information required for packet forwarding as ensuring seamless packet forwarding, thus QoS(Quality of Service) is continuously maintained while reliability of the router system is improved. State management flags having the first or second bit value are set in each entry of a table where information for packet forwarding is stored(401). State conversion of a routing processor is confirmed(402). If the routing processor is converted into an abnormal state from a normal state, the state management flags of all of the entries within the table are changed into the first bit value indicative of existing entries(403,404). If the routing processor is converted into the normal state from the abnormal state, the information for packet forwarding is received from the routing processor to update table information according to the received information, and the state management flags of the updated entries are changed into the second bit value indicative of new entries(404-405).

Abstract: The system of the present invention guarantees quality of service with respect to packets transmitted/received between an external network capable of providing differentiated services and a home network. The system includes a packet classifier, a marker, a priority class queue, a scheduler and a token bucket. The packet classifier classifies the packets according to addresses and traffic types. The marker allocates information on priorities to packets transmitted from the home network to the external network. The priority class queue has a plurality of queues classified according to the priorities. The scheduler services packets stored in the priority class queue according to the priorities. The token bucket drops packets, bandwidths of which are above a preset maximum bandwidth, when the packets are generated.

Abstract: PURPOSE: A high speed router system is provided to distribute a portion of an IP(Internet Protocol) packet and a portion of an Internet control message in a line processor, thereby reducing processing load of a non-forwarding packet concentrated on a main processor. CONSTITUTION: Line processor nodes(101) comprise as follows. External physical link connection blocks(1011) are physically connected to external networks. Network processor blocks(1012) perform routing lookup processes after interpreting destination addresses of packets, and forward the routing lookup processes. Microprocessor blocks(1013) communicate with a main processor node(102) with configuration information of the line processor nodes(101). The main processor node(102) consists of a microprocessor block(1021) for communicating with the line processor nodes(101) and processing a routing protocol collecting routing information.

Abstract: Disclosed are a method for forwarding a packet and an apparatus therefor. The method of forwarding a packet includes the steps of: analyzing a plurality of path properties for transmitting the packet; analyzing a signature of the packet; determining a path having the lowest transmission delay among paths based on the path properties when the signature satisfies a predefined packet property; and transmitting the packet through the path having the lowest transmission delay. Thus, an optimal path can be determined from the paths and the packet can be transmitted through the determined optimal path.
