摘要： Provided is a protection switching method via forwarding table correction in an Ethernet ring network. Upon detecting a failure in a link, a node generates a protection switching frame including an address list of a forwarding table corresponding to a port connected to the link, and transmits the protection switching frame to a port at an opposite direction of the link. A node that receives the protection switching frame deletes its own address from the address list included in the protection switching frame, and changes a port number of an address in the address list of the protection switching frame from among addresses of the forwarding table corresponding to a port that received the protection switching frame to a port number in an opposite direction of the port that received the protection switching frame or deletes the port number of the address in the address list.

摘要： The present invention is directed to an optical router device that is configured to route optical packets in a TDM/WDM optical network. The optical device is disposed in a node of the WDM optical network. The WDM optical network is configured to accommodate a plurality of wavelength channels. Each of the plurality of wavelength channels is configured to propagate optical packets in a time division multiplexed (TDM) arrangement. Each optical packet includes a baseband-payload and a subcarrier modulated (SCM) header. The device includes an optical WDM demultiplexer configured to demultiplex the plurality of wavelength channels. A header recovery component is coupled to the optical WDM demultiplexer. The header recovery element is configured to recover the SCM header in each optical packet propagating on each demultiplexed wavelength channel.

摘要： Provided is an apparatus for transferring optical data in an optical switching system using time synchronization. The apparatus performs time synchronization on optical data to input the optical data at regular intervals through fiber delay lines for time synchronization respectively disposed on input ports. Therefore, the apparatus can efficiently reduce a data blocking rate in comparison with a conventional optical switching system using an asynchronous electric buffer without a synchronous process, and achieve the same performance as conventional asynchronous technology despite using fewer wavelength converters and buffers, thus reducing system cost. In addition, using dynamic time synchronization modules, the apparatus performs time synchronization for minute time variation due to an environment such as temperature.
