Abstract: A method for selectively displaying advertising materials includes receiving an advertising material and an associated advertising rule, wherein the advertising rule specifies a restriction on user generated content that can be displayed together with the advertising material, and receiving user generated content via a network. The method further includes determining if the user generated content violates the advertising rule, and if the user generated content violates the advertising rule, generating a web page containing the user generated content without the advertising material.

Abstract: Embodiments of the present invention provide an optical network and switch architecture that provides non-blocking routing from an ingress router to an egress router in the network on a port-to-port basis. The present invention provides routing for fixed and variable length optical data packets of varying types (including Internet Protocol (IP), data, voice, TDM, ATM, voice over data, etc.) at speeds from sub-Terabit per second (Tbps), to significantly in excess of Petabit per second (Pbps). The present invention includes the functionality of both large IP routers and optical cross-connects combined with a unique, non-blocking optical switching and routing techniques to obtain benefits in speed and interconnected capacity in a data transport network. The present invention can utilize a TWDM wave slot transport scheme in conjunction with a just-in-time scheduling pattern and a unique optical switch configuration that provides for non-blocking transport of data from ingress to egress.

Abstract: One embodiment of the present invention includes a router comprising an ingress edge unit with one or more ports and an egress edge unit with one or more ports connected by a switch fabric. The ingress edge unit can receive optical data and convert the optical data into a plurality of micro lambdas. The ingress edge unit can convert the incoming data to micro lambdas by generating a series of short-term parallel data bursts across multiple wavelengths. The ingress edge unit can also wavelength division multiplex and time domain multiplex each micro lambda for transmission to the switch fabric in a particular order. The switch fabric can receive the plurality of micro lambdas and route the plurality of micro lambdas to the plurality of egress edge units in a non-blocking manner.

Abstract: Embodiments of the present invention provide a system and method for routing optical data. In one embodiment of the present invention, data can routed in a non-blocking fashion from a plurality of the ingress edge units to a plurality of egress edge units by selectively connecting the ingress edge units to the egress edge units at a photonic core. Switching at the photonic core can be driven by a clock signal and does not require an electrical to optical conversion to occur at the core. This can allow switching on the nanosecond level, substantially faster than many prior art systems.

Abstract: Systems and methods for optical cross connects which switch data at a container (packet) level. In one embodiment, a plurality of optical switch edges are coupled to an optical switch core via a minimal number of optical fibers. The switch core is configured to optically switch data from an ingress edge to one of a plurality of egress edges in a nonblocking fashion. The ingress edge receives data streams and distributes the data among a plurality of container processors. Each of these container processors produces an optical signal of a different wavelength, which can then be multiplexed with others to form a multiple-wavelength optical signal that is transmitted to the switch core. The switch core then switches successive portions (containers) of the multiple-wavelength signal to the egress edges to which they are respectively destined. The respective egress edges perform the reverse of this process to form output data signals.

Abstract: A system and method for providing non-blocking routing of optical data through a telecommunications router that allows full utilization of available capacity. The router includes a number of data links that carry optical data packets to and from an optical router. The optical router includes a number of ingress edge units coupled to an optical switch core coupled further to a number of egress edge units. The ingress edge units receive the optical data packets from the data links and aggregate the optical data packets into “super packets” where each super packet is to be routed to a particular destination egress edge unit. The super packets are sent from the ingress edge units to an optical switch fabric within the optical switch core that routes each super packet through the optical switch fabric to the super packet's particular destination egress edge unit in a non-blocking manner (i.e., without contention or data loss through the optical switch fabric).
