20090148162 | METHODS FOR NON-WAVELENGTH-CONVERTING MULTI-LANE OPTICAL SWITCHING - 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. | 06-11-2009 |
20090313465 | METHODS AND APPARATUS FOR SECURING OPTICAL BURST SWITCHING (OBS) NETWORKS - An optical network, having an optical communication link and first and second routers. The first router receives and classifies data, then forms a data burst based on destination. The first router sends an encrypted header and the data burst via the optical link. The second router, at least one hop from the first router, receives, decrypts and authenticates the header. Then, the second router extracts data burst information from the header and determines whether the address of the second router is the destination address for the data burst. If so, the second router receives the data burst and sends data to an appropriate line interface. If not, the second router selects and reserves a wavelength on a second optical link for the data burst. The second router selects an encryption key for the header, encrypts and sends the header, and then routes the data burst to the selected wavelength. | 12-17-2009 |
20120148242 | Dense Wavelength Division Multiplexing Multi-Mode Switching Systems and Methods for Concurrent and Dynamic Reconfiguration with Different Switching Modes - 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. | 06-14-2012 |
20130094856 | METHODS AND APPARATUS FOR TRAFFIC MANAGEMENT IN MULTI-MODE SWITCHING DWDM NETWORKS - A Wavelength Division Multiplexing (WDM) multi-mode switching system and method and method provides concurrent switching 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 in the WDM multi-mode switching systems may provide a traffic management module that processes incoming data and routes the data for transmission in an electronic packet switching (EPS), optical burst switching (OBS), or optical circuit switching (OCS) modes via a WDM link. | 04-18-2013 |
20130182574 | METHOD AND SYSTEM OF CONGESTION CONTROL IN A MOBILE VIRTUAL NETWORK - An approach is provided for dynamic congestion control among mobile virtual routers. A determination is made whether a congested segment of a network of a plurality of physical routers. A temporary congestion point is created at a mobile virtual router to divert traffic away from the congested segment using logical tunnels over non-congested physical links, wherein the mobile virtual router is configured to utilize resources of at least two of the physical routers. | 07-18-2013 |
20130182605 | METHOD AND SYSTEM FOR PROVIDING A MOBILE VIRTUAL ROUTER - An approach is provided for creating mobile virtual routers (MVRs). A mobile virtual router is dynamically configured based on an application, wherein the mobile virtual router includes a control plane instance, a forwarding plane instance, and a management plane instance. Data associated with the application is forwarded over the network using the mobile virtual router. The control plane instance, the forwarding plane instance, and the management plane instance are moveable among the plurality of physical routers. | 07-18-2013 |
20130182606 | METHOD AND SYSTEM OF FORMING A MOBILE VIRTUAL NETWORK - An approach is provided for creating a mobile virtual network. A virtual network is created to include a plurality of mobile virtual routers. A determination is made whether the virtual network has sufficient resources to satisfy a dynamic virtual network requirement. The size of the virtual network is adjusted based on the determination. | 07-18-2013 |
20130185432 | METHOD AND SYSTEM FOR SHARING ROUTER RESOURCES VIA A MOBILE VIRTUAL ROUTER - An approach is provided for creating a single mobile virtual router (MVR) to share pooled resources. A mobile virtual router is formed to utilize resources of multiple routers of a network, wherein the routers include one or more physical routers, one or more virtual routers, one or more other mobile virtual routers, or a combination thereof. The resources of the single mobile virtual router are dynamically partitioned in response to an operational criterion of the network. | 07-18-2013 |
