A multi-mode configuration module for managing switching for an EPS, OCS, and OCS mode is provided. The multi-mode configuration module may include a multi-mode configuration processor, wherein said multi-mode configuration processor receives configuration information for an EPS, OCS, or OBS mode. The module may also provide an optical configuration processor coupled to said multi-mode configuration processor, wherein said optical configuration processor manages wavelength routing of an optical switching fabric; and an electronic configuration processor coupled to said multi-mode configuration processor, wherein said electronic configuration processor manages routing of an electronic switching fabric.

Methods and apparatuses for DWDM multi-mode switching router and dynamic multi-mode configuration and reconfiguration

A Wavelength Division Multiplexing (WDM) multi-mode switching system and method and method provides concurrent switching in various switching modes. For example, WDM links may communicate data in various switching modes including, but not limited to, an electronic packet switching (EPS) mode, optical circuit switching (OCS) mode, and optical burst switching (OBS) mode. Edge routers and core routers in the WDM multi-mode switching systems and methods provide switching and processing necessary to handle data provided in the various switching modes. Further, the WDM multi-mode switching systems and methods can also provide dynamic reconfiguration between the various switching modes.

Dense wavelength division multiplexing multi-mode switching systems and methods for concurrent and dynamic reconfiguration with different switching modes

A method for providing multi-wavelength switching. The method comprising receiving a plurality of signals through at least one input port, and separating the plurality of said signals into at least one wavelength signal set based on wavelengths, wherein a first wavelength signal set of said at least one wavelength signal sets corresponds to a first wavelength. The method further comprises providing a plurality of output lanes to at least one output port, and determining if two signals from said first wavelength signal set traveling on said first wavelength are scheduled output from an output port during an overlapping time period through said plurality of output lanes. The method further comprises determining if one of said plurality of output lanes is available during said overlapping time period when said two signals are schedule for said output port during the overlapping time period, wherein a first signal of said two signals is routed for output on an available lane if one of said plurality of output lanes of said output port is available.
