摘要： In today's reconf?gurable optical add/drop multiplexer (ROADM) based optical node, ROADMs multiplex (and demultiplex) colored optical signals to form wavelength-division multiplexed (WDM) signals. Transponders connected to the ROADMs' add/drop ports convert noncolored optical signals to colored optical signals (and vice versa). Dedicating transponders to given ports degrades the node's ability to route around network failures. Example embodiments of the invention include an optical node and corresponding method for routing optical signals within an optical node that compensate for this inflexibility. The optical node may include two ROADMs to transmit respective WDM signals onto at least two internode network paths and a routing module that can direct channels of the same wavelength along different internode network paths. Advantageously, a transponder may transmit (receive) different signals at the same wavelength to (from) different network node interfaces within the optical node, thereby improving the optical node's ability to route around network failures.

The method includes measuring a length and width of a card module slot of the chassis, a first opening width of a first rack for housing the chassis, and a second opening width of a second rack for housing the chassis, where the first opening width is greater than the second opening width.

If the first opening width is sufficiently wide, a dimension of at least one parameter related to the configuration of the chassis is determined so that the second opening width is a multiple of a total chassis width of the chassis. A chassis configured according to the method is provided.

摘要： Erroneous data due to faults are prevented from propagating through a distributed network node having diversely routed communications links by using a fault masking technique that eliminates the 60 ms of error propagation time associated with SONET networks. The fault masking technique can also prevent random bit errors from propagating through the distributed network node. A frame alignment technique used in the network node is scalable for very wide words (e.g., 128 bits) for use with high speed optical communications protocols, such as OC-192.

摘要： Systems and methods for cell-based wrapped wave front arbiter (WFFA) with bandwidth reservation are disclosed. The method for reserving bandwidth of a given priority using the WWFA for arbitrating bandwidth among virtual links between input and output ports, each link supporting priorities and corresponding to an arbitration unit (AU) of the WWFA generally includes performing at least one arbitration pass of a wave front of the WWFA where AUs having a reserved bandwidth request of a given priority and reserved bandwidth credit of the given priority compete for the bandwidth associated with the wave front, and where AUs not having a reserved bandwidth request of the given priority and reserved bandwidth credit of the given priority do not compete for the bandwidth, and performing at least one subsequent arbitration pass where AUs having a reserved bandwidth request of the given priority compete for the bandwidth. Each virtual link perferably supports a high priority and a low priority such that the WWFA performs four passes. Each priority of each virtual link may be associated with a bandwidth credit accumulator register indicating the level of remaining reserved bandwidth credit, a reserved bandwidth weight register for programming a predetermined level of reserved bandwidth, a request counter register for tracking the number of bandwidth requests, a rate counter register that is periodically incremented to generate reserved bandwidth credits for the bandwidth credit accumulator register, and an optional burst register having a predetermined value for limiting the maximum value of the bandwidth credit accumulator register.

摘要： Optical networks are increasingly employing optical network nodes having multiple interfaces to allow a node to direct optical signals received at any interface to any other interface connected to the node. Constructing a larger wavelength selective switching (WSS) module used in such a node can be complex and expensive. A method an apparatus for constructing a large WSS using parallelism is provided. In example embodiments, a larger WSS may include multiple parallel non-cascaded smaller WSSs and an optical coupler configured to optically couple the multiple parallel, non-cascaded smaller WSSs. This technique may be used to construct both N x 1 and 1 x N WSSs. Because the technique employs multiple parallel, non-cascaded WSSs, all inputs of a larger N x 1 WSS and all outputs of a larger 1 xN WSS are available receive or transmit external signals rather than being rather than being unavailable due to, for example, cascading smaller WSS devices together.

摘要： The specification discloses methods and apparatus for selecting the better of two or more copies of a cell in a cell-oriented redundant switching system (107, 108) connected to an external communication network. In the preferred embodiment, the best cell copy selection (109) aligns redundantly transmitted cell streams before selecting cells for insertion in the data stream. Because the streams are aligned before the selection is made, the best cell copy selector compares each cell at the same instant in time, rather than basing its selection on past events.
