摘要： An apparatus and a method of transmitting a normal packet from a transmitting node in a Wavelength Division Multiplexing (WDM) based network system are included. Using the apparatus and method in accordance with the present invention, the WDM based network system is able to avoid any collisions between the packets that are already loaded into the mini slots and the packets that are about to be loaded into the mini slots. Therefore, the defects of the synchronous packet transmitting/receiving method are eliminated. The packet-receiving channel of the packet-receiving node can be set to a fixed wavelength; consequently, the problems of the related art techniques are solved. In conclusion, the efficiency of the whole network system is greatly enhanced.

摘要： The present invention relates to packet switched interconnection protocols for use in high-speed optical Star-configured Local Area Networks (LANs). In the present Star LAN, a plurality of N+1 wavelength division multiplexed (WDM) channels are provided for use by M transceivers connected to the Star coupler (15), where preferably M>N. N of the N+1 WDM channels are used for transmission of data packets, and the remaining WDM channel is used by all transceivers for transmitting control packets only. In the present protocols, a transmitter (11) in an active transceiver first send a control packet over the control channel using a first protocol such as, for example, ALOHA or CSMA. The control packet includes the transmitter's unique address, the destined receiver's address, and the address of the data channel to be used in transmitting the associated data packet. Immediately after the control packet is sent, the associated data packet is transmitted over the chosen one of the N data channels using a second protocol such as, for example, ALOHA, CSMA or N-Server Switch. In the Star network, the transceivers receive their own transmissions and detect if a collision or not has occurred, and if a collision is detected the transmission procedure is repeated until successful.

摘要： PURPOSE: A self-healing annular optical communication network of WDM(Wavelength Division Multiplexing) is provided to effectively operate a network by reducing the number of optical fiber links to half by using a circulator. CONSTITUTION: Each node of an annular optical communication network(6) includes an optical branch couplers(310a,340a) having a demultiplexer and a multiplexer each with 1xN capacity. A pair of switching units(210a,280a) are connected with an optical fiber line for protectively switching. Each node also includes a pair of circulators(410a,480a) connected between the optical branch couplers(310a,340a) and the pair switching units(210a,280a). Two ports of the circulators(410a,480a) are connected to the optical switching units(210a,280a) and one port thereof is connected to the optical branch couplers(310a,340a). In this case, a signal inputted to the first port is outputted to the second port, and a signal inputted to the second port is outputted to the third port. The optical switching units(210a,280a) switch an optical signal by discriminating a case where an optical fiber link is normal with respect to two output terminals respectively connected to the two ports of the circulators(410a,480a) and a case where the optical fiber link has an error.

摘要： An optical cross-connect node architecture interfaces plural optical fiber input and output links, each link containing plural wavelength channels. In one embodiment, the input links are connected to an optical coupler. Pairs of tunable optical filters and optical wavelength converters are each connected to an output port of the optical coupler and perform wavelength channel routing and switching in the wavelength domain, i.e., without the need for any optical space switch. In another embodiment, an additional input wavelength converter is connected to each input fiber link to convert the plural wavelength channels on each link to different, noninterferring wavelengths. This prevents wavelength contention in the optical coupler to which the input wavelength converters are connected. New fiber links may be added in modular fashion without significant impact on the pre-existing optical cross-connect structure. Similarly, new wavelength channels may also be multiplexed onto existing fibers to provide wavelength modularity without having to reconfigure the node.

摘要： PURPOSE: A packet transmission/reception method of a network system adopting a WDM(Wavelength Division Multiplexing) is provided to prepare a separate flow capable of prohibiting a collision between packets and so unify the transmission/reception procedure of the packet between nodes as a synchronization system. CONSTITUTION: A network system(200) of a WDM method includes channels(40) arranged with a ring shape. Nodes(50) form a series of networking relation through the channels(40). A plurality of mini-slots(4) are flowed to the respective channels(40) in order to convey the packet. The nodes(50) can reserve fixed reception channels, for example, a node 0(51) can reserve a channel(3) as a fixed reception channel and a node 1(52) can reserve a channel(1) as a fixed reception channel and a node(53) can reserve a channel(2) as a fixed reception channel. At the respective nodes(50), a wave tunable transmitter(61), a wave tunable receiver(63), a wave fixed receiver(62), a queue(65), and a priority queue(64) are arranged uniformly. At this time, a series normal packets for using any node as a target is stored stably to the queue(64).
