    摘要: A dynamic bandwidth allocation (DBA) processor comprises a DBA co-processor having DBA co-processor components and operative to perform and accelerate DBA functions, and a processing core logically coupled to the DBA co-processor through a processing bus and operative to configure and dynamically control all the DBA co-processor components and to run sections of algorithms that cannot be accelerated on the DBA co-processor. The DBA processor significantly accelerated the bandwidth allocation in a communications network such as an optical communications network or a fast wireless network. The DBA co-processor and the processing core may be integrated on a chip.

    摘要: Systems and methods for bandwidth doubling in an Ethernet passive optical network (EPON) enable an optical line terminal (OLT) to transmit downlink to at least one double rate optical network unit (ONU). The double rate transmission is preferably facilitated by use of single rate devices (OLT and ONU) functionally connected to provide the double rate capability. The methods include packet-by-packet multiplexing, bit-by-bit line code interleaving, doubling an inter-packet gap (IPG) length, defining windows of transmission for different transmission rates, using the 8B/10B code, removing the 8B/10B code from just the downlink transmission and symbol-by-symbol multiplexing is downlink transmissions from the double rate OLT.

    摘要: A protocol for communicating data on a passive optical network conforming to the Ethernet standard provides processes for remote network node discovery and synchronization. Uplink packet transmissions to a central controller, such as an optical line terminal, are scheduled by the central controller. Downlink packets from the central controller to a remote network node, such as an optical network unit, are encrypted to preserve privacy, and the key used for encryption is changed periodically. The protocol further provides processes for detecting the loss of physical or logical connection between the central controller and the remote network nodes.

    摘要: In a passive optical network that includes a plurality of optical network units (ONUs) coupled to an optical line terminal (OLT), dynamic bandwidth allocation (DBA) methods and algorithms designed to support a short delay as well as best effort services, while maintaining fairness between subscribers. In a preferred embodiment, a DBA allocation method comprises the steps of calibrating requests issued by each of the ONUs to obtain respective calibrated requests, allocating a bandwidth amount to each ONU based on the calibrated requests using an allocation scheme selected from the group consisting of an under-utilization allocation scheme and an over-utilization allocation scheme, and based on the bandwidth allocation, granting the ONUs a second plurality of constant delay grants per each cycle.

    摘要: In a system that includes a host and a memory controller that is separate from the host and stores data for the host in a non-volatile memory, a method for data storage includes transferring from the memory controller to the host one or more source blocks from the non-volatile memory for compaction. The source blocks are compacted in the host by copying valid data from the source blocks into one or more destination blocks. The destination blocks are transferred from the host to the memory controller, and the destination blocks are stored by the memory controller in the non-volatile memory.

    摘要: A method includes storing data in an analog memory cell by writing an analog value into the memory cell. After storing the data, the data stored in the memory cell is read by discharging electrical current to flow through the memory cell, during a predefined time interval, while applying a variable voltage to a gate of the memory cell. A fraction of the predefined time interval, during which the variable voltage allows the electrical current to flow through the memory cell, is estimated. The stored data is estimated based on the estimated fraction.
