    摘要: A packet processing apparatus and method are provided. The packet processing apparatus changes a size of an input packet, analyzes the input packet to perform a second layer associated process, generates basic delivery headers of the input packet, processes the input packet to which the basic delivery headers are inserted according to a type of the input packet, transforms the header of the input packet to which the basic delivery headers are inserted, and transitions the header-transformed input packet to delivers the packet. Accordingly, it is possible to process various packets without addition of separate process to the packet processing apparatus. In addition, a use efficiency of a network processing unit can be optimized, so that it is possible to increase a packet processing rate and performance.

    摘要: Provided are a forced protection switching method and a forced protection switching clearing method in an Ethernet ring network. When an operator desires to block a port of a specific node for maintenance and repair, the operator gives a forced switching (FS) command to the specific node in order to block the port. When the operator desires to clear FS, the operator gives a clear command to the specific node in order to clear the blocked port. As a result, operation flexibility of the Ethernet ring network is provided.

    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.
