    摘要: Systems and methods according to these exemplary embodiments provide for mechanisms and methods that allow for improving the efficiency of a passive optical network (PON). Upstream data transmission can occur by allowing an optical network unit (ONU) cycle to overlap more than one GPON transmission convergence (GTC) frame. Additionally, or alternatively, multiple different bandwidth maps can be transmitted per dynamic bandwidth allocation (DBA) cycle to inform ONUs of their respective, upstream bandwidth allocations.

    摘要: Exemplary embodiments provide for methods and systems that enable frame generation by fields taken from various queues. Protocol control can also or alternatively be distributed so that one or more header fields can be generated separately from other portions of a frame, e.g., the payload. The one or more header fields can be entered into queues from which they are taken to generate frames.

    摘要: Systems and methods according to these exemplary embodiments provide for methods and systems that enable decoupling of medium access control (MAC) functions from other optical transceiver functions to, for example, promote scalability of passive optical networks (PONs). A MAC frame processing unit can communicate MAC frames to optical transceiver modules via an interconnect using an encapsulating frame according to another communications protocol, e.g., XAUI.

    摘要: The invention relates to a method and circuit for aligning a serial bit stream with a parallel output. The method comprises latching Q bits from the serial bit stream into a register, locating a position P of a first bit of a start of frame delimiter (SFD) in the register and discarding P-1 bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output. The circuit comprises a latch, a fault tolerant analysis logic (FTAL) for locating a position P of a first bit of a start of frame delimiter (SFD) in the register and a shift register for discarding P-1 bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output.

    摘要: A framework for providing cluster-wide cryptographic operations, including: signing, sealing, binding, unsealing, and unbinding. The framework includes an interface module (a.k.a., HAT agent) on each of a plurality of nodes in the cluster. Each HAT agent is configured to respond to an application's request for a cluster crypto operation by communication with other HAT agents in the cluster and utilizing a trusted platform module local to the node where the HAT agent resides.
