More particularly, there is provided a technique for identifying virtual lanes using multi-frame alignment signals (MFASs) at a receiver without modifying an existing frame structure of an optical transport network signal by periodically changing a rotating direction of the virtual lanes when applying an Ethernet virtual lane scheme to a ultra-high speed OTN signal, particularly to OTU4 (100G).

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： The present invention relates to a method and apparatus for transmitting data over a WLAN mesh network. Transmission sections of priority frames and general frames are initially set, and the priority frame transmission section is varied step-by-step within a specific range. Thus, QoS with respect to data requiring the real-time property can be guaranteed and transmission of general frames can be guaranteed to some degree. Accordingly, there is an effect that data transmission efficiency can be improved significantly.

摘要： A packet forwarding apparatus forwards packets by hardware implementation in a packet switch system for an internet protocol service. In the packet forwarding apparatus, an interface transmits/receives a packet through interfacing with a data link layer. A bus operator converts the packet received from the interface by a pre-set logic. A header parser parses a header of the converted packet. A network search engine controller receives a parsed result and the packet from the header parser and controls a command for forwarding the packet by interworking with an external network search engine and a processor.
