    Abstract: An apparatus and method for switching and/or routing electronic data between two networks communicating at different bit rates, where the bit rate of the faster network divided by the bit rate of the slower network is a non-integer. A switching/routing unit interconnects the networks via two set of lanes, one set connected to each network. Each lane communicates at a bit rate that is a common factor of the two bit rates. One set of lanes communicates with a set of transceivers that communicate at the faster bit rate on the faster network. The other set of lanes communicates with a (larger) set of network elements (NEs) that communicate at the slower bit rate on the slower network. Each transceiver and NE is structured so that the total bit rate of the lanes communicating with it is equal to the bit rate of its respective network.

    Abstract: An optical packet switch switches optical packets according to bit-rates at which the optical packets are provided. For example, optical packets that are received at similar bit-rates may be routed to a destination at separate time slots over a single channel wavelength, and optical packets that are received at different bit-rates may be routed to the destination over separate channel wavelengths. When optical packets are provided at different bit-rates on a plurality of input paths, optical packets provided at low bit-rates may be compacted before switching to the destination. Alternatively or additionally, the bit-rates of the optical packets may be balanced before switching to the destination. Bandwidth contention among optical packets may be resolved by polarizing optical packets originating from separate input paths in different polarization directions, and merging optical packets having different polarization directions onto a single switched channel wavelength. Compaction of optical packets may alternatively be employed for resolution of bandwidth contention. Related apparatus and methods are also described.
