摘要： An optical network includes an optical ring having a plurality of subnets. The subnets each include one or more add/drop nodes that are coupled to the optical ring and that passively add and drop traffic to and from the optical ring in one or more wavelengths. The optical network also includes a plurality of gateway nodes that are each coupled to the optical ring at a boundary between neighboring subnets. Each gateway node forwards a first copy of a received optical signal to a multiplexer/demultiplexer unit of the gateway node, which selectively forwards or terminates the traffic in each wavelength of the first copy. The gateway nodes also forward a second copy of the received optical signal to a regeneration element. The gateway nodes selectively forward or terminate the traffic in each wavelength of the first copy at the multiplexer/demultiplexer unit. Moreover the gateway nodes selectively perform one of the following on the traffic in each wavelength of the second copy at the regeneration element: terminate the traffic, forward the traffic after regenerating the traffic, or forward the traffic after regenerating and converting the wavelength of the traffic.

摘要： A method and system for forwarding packets within containers in a data communication network. Each container may include packets or additional containers. Packets/containers are stored within containers in a predetermined format that includes a Type field, a Length field and a Value field. The Type field includes an indication whether the respective packet/container is the last packet/container in the respective sequence. The Length field specifies the Length of the following Value field and the Value field comprises the payload, which may comprise additional packets or containers. A header, such as an MPLS shim header, is applied to containers to be transmitted over the network. Containers are closed and scheduled for transmission once when it is determined that the addition of a packet/container to the overall container would exceed a predetermined maximum container size or when a timer measures a predetermined time period from the arrival of the first packet within the container.

摘要： A system and method for providing quality of service guarantees in a packet-switched network is provided. A network including nodes linked together by communication links includes a management node for governing the performance of the nodes. Ingress and egress rate restrictions are defined at the nodes and the management module may disallow a portion of a requested transmission to a node if the requested transmission would result in a violation of one of the ingress and egress rate restrictions. Disallowance of a requested transmission may be made by the management node if either an ingress rate restriction of the transmitting node or an egress of the receiving node would be violated by allowance of the requested transmission.

摘要： A method of determining end points for an optical channel in an optical network (Fig.1) to off-load traffic from a target optical link is provided. The method includes the steps of identifying ingress network nodes sourcing traffic through the target optical link, and determining an average ingress bandwidth sourced by the ingress network nodes. Thereafter, the method includes the steps of identifying egress network nodes sinking traffic from the target optical link, and determining an average egress bandwidth sunk by the egress network nodes. The optical channel start point candidates are identified to include ingress network nodes sourcing more traffic than the average ingress bandwidth, and the optical channel end point candidates are identified to include egress network nodes sinking more traffic than the average egress bandwidth.

摘要： In accordance with one embodiment of the present invention, a system for monitoring a performance characteristic of an intensity modulated phase shift keying optical signal includes a splitter, a first detector, and a second detector. The splitter is operable to receive an intensity modulated phase shift keying optical signal from an optical network and route at least a portion of the signal to the first detector. The first detector generates an electrical signal based on the received optical signal without demodulating the optical signal. The second detector measures a performance characteristic of the intensity modulated phase shift keying optical signal based on a signal indicative of the filtered signal.

摘要： A method for protection switching includes receiving an optical signal from a transponder coupled to a client and optically splitting the signal to a first output and a second output. The first output is coupled by a first optical add-drop multiplexer to a first optical fiber, and the second output is coupled by a second add-drop multiplexer to a second fiber. The method further includes selecting one of the output signals for the working channel, and communicating the selected output signal to an optical network. During communication of the selected output signal to the optical network, the method includes monitoring for a failure condition in the optical network and, if the failure condition is detected, selecting the other output signal as the working channel and communicating the new selected output signal.
