Abstract: There is provided a new architecture for all-optical logic architecture. In this architecture the gate is partitioned into a linear front-end followed by a nonlinear back-end. The logic calculation is practically performed within the linear stage, easing the requirements placed on the non-linear part and thus reducing the gate complexity. The new structures provide flexibility and improved performance for the all-optical logic. The proposed scheme may be integrated optics/electronics. An important additional attribute of our all-optical logic family is reconfigurability, i.e. the ability of the hardware architecture or devices to rapidly alter the functionalities of its components and the interconnection between them as needed.

The method includes the steps of: receiving the multiplex; associating a transmitter timing information to media packets; whereas the multiple media packet streams are associated to different time bases; transmitting the media packets and the associated transmitter timing information over a timing violation inducing communication channel to a receiver; receiving, by the receiver, the transmitter timing information and the media packets; providing at least one timing violation compensated stream of media packets in response to the transmitter timing information.

Abstract: A cable modem termination system includes a data over cable service interface specification (DOCSIS) subsystem that manages a flow associated with a gate and a gate manager (GM) that manages a state of the gate. When the flow is admitted by the DOCSIS subsystem, the DOCSIS subsystem signals to the GM to transition the state of the gate to a reserved state. The GM transitions the state of the gate to the reserved state when the DOCSIS subsystem signals to the GM to transition the state of the gate to the reserved state. When the flow is activated by the DOCSIS subsystem, the DOCSIS subsystem signals to the GM to transition the state of the gate to a committed state. The GM transitions the state of the gate to the committed state when the DOCSIS subsystem signals to the GM to transition the state of the gate to the committed state.
