    摘要： A method for providing mobility of a mobile node in a packet transport network, and a packet transport network system are provided. The packet transport network system includes a plurality of gateway switches configured in a plurality of packet transport access networks to connect a packet transport core network and transmit/receive a packet to/from a certain terminal via a certain access switch. When the certain terminal moves, each gateway switch updates a tunnel mapping and management table according to the movement of the certain terminal, allocates a pre-set tunnel by using information included in the tunnel mapping and management table, and transmits/receives a packet to/from a counterpart terminal via the allocated tunnel. Thus, a packet loss and delay due to the influence of handover occurring when the mobile node moves between networks can be minimized and the handover procedure can be simplified.

    摘要： An apparatus for processing packets in a high speed router and a method thereof are provided. The high speed router includes a forward processor and a control processor where the forward processor having an input terminal processor and an output terminal processor. The output terminal processor manages a Layer 2 Address Table by dividing the Layer 2 Address Table into a layer 2 indirect address table and a layer 2 direct address table and by managing them. The indirect address table is directly indexed in the Next-hop Table of the input terminal processor table. The direct address table is composed of a hashing table for a destination IP address. Therefore, the system efficiency can be improved by reducing the memory which is used for storing the forwarding information table occupied by the forward processor and by reducing the IPC message between the control processor and the forwarding process.
