摘要： PROBLEM TO BE SOLVED: To provide a packet switching node, having a pipelined packet processing architecture which processes received packets. SOLUTION: Packet header field values, comprising packet addresses unique for a received and determined packet frame type, are selectively extracted, which determines the initial action to be performed for packets; searches packet switching information to be pursued by a packet switching node based on the packet address information; classifies packets as one of plural packet flows; changes an initial switching response and a packet header based on either classified packet flow, or default port action corresponding to an input port, and processes packets, based on a switching response. Advantage here is obtained by pipelined packet processing which can simplify remained processing regarding improper packets. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fail-over mechanism, based on hardware which makes quick end-to-end recovery. SOLUTION: Hardware logic is sent from one end of a network to another, and then returned packets in important parts are generated, sent, received, and processed periodically. When a communication network node or a communication link failure is experienced along a transfer path, the hardware logic changes the influenced traffic in the middle of carriage to previously established backup transfer path in typically less than a few microseconds. The advantage of enabling continuous transmission of the supplied communication service, which has improved resilience, and availability of communication network is derived by quick fail-over performed between the terminals (end-to-end).

摘要： PROBLEM TO BE SOLVED: To disclose a method and an apparatus for controlling echo canceller in a communication channel with a very small amount of calculation.
SOLUTION: In the method and the apparatus for controlling the echo canceller in the communication channel, an input signal from the communication channel is made to be a sub-band by a decimeter 14 and a sub-band filter 16. An echo position within the sub-band is identified by an echo position deciding unit 12 and a peak detecting unit 20, and is used for controlling the echo canceller. Typically, the echo canceller is a full band echo canceller having an adaptive filter, and an identification echo position is used for controlling the filter coefficient.
