    摘要: A system provides multidimensional tuple Hilbert ordering within a linear storage structure to enable more consistent and efficient access to stored multidimensional tuples. The database system comprises a tuple storage module that receives multidimensional data elements, where each multidimensional data element is defined by a plurality of different object types, and where each object is associated with a different dimension within a multidimensional data space. The tuple storage module further forms a respective tuple for each of the multidimensional data elements by mapping each object to an associated reference and applies a Hilbert function to the references of each of the tuples to determine a respective Hilbert ordering for each of the tuples. The system further comprises a linear data storage structure that includes a B-tree for storing the Hilbert ordering.

    摘要: Techniques are described of applying on-line analytical processing (OLAP) to associative databases. For instance, a database adapter implemented in computer hardware or software may automatically create dimensions in a multidimensional dataset for data types in an associative database. The database adapter may then query the associative database for metadata that describes index values of each dimension of the multidimensional dataset. The database adapter may then query the associative database for data values to populate individual cells of the multidimensional database.

    摘要: A method provides advertisements to optical network units (ONUs) by an optical line terminal (OLT), wherein the advertisements enable the ONUs to identify free channels from a plurality of wavelength-division multiplexing (WDM) channels in a passive optical network (PON). The method includes: transmitting from the OLT to the ONUs an advertisement identifying a free channel for each of a plurality of incompatible channel (ICH) groups, receiving a request from an ONU for the advertised free channel of an ICH group, authenticating the requesting ONU via the advertised free channel, allocating the advertised free channel to the requesting ONU upon successful authentication of the requesting ONU, and transmitting an updated advertisement from the OLT to the ONUs.

    摘要: An optical access network (5) comprises optical network units (10) connected to a node (40). A monitoring unit (35) determines information indicative of energy consumption at the optical network unit (10) over a period of time. An optical network unit (10) can operate in operating states/modes which differ in their energy consumption. Monitoring unit (35) can determine the information by determining a time that an optical network unit spends in the different operating states/modes. Monitoring unit (35) can use a state machine (31) at the node (40) which represents the optical network unit (10). An optical network unit (10) can locally record time spent in states/modes and forward this to the monitoring unit (35). An optical network unit (10) can locally monitor energy consumption and forward this to the monitoring unit (35). An operational parameters of the access network (5) can be modified based on the information determined by the monitoring unit (35).

    摘要: A fiber optic coupler includes a housing that receives upstream optical signals from drop optical fibers that are optically coupled to optical network units in a power splitting passive optical network and provides an aggregate upstream optical signal to a trunk optical fiber that is optically coupled to an optical line terminal in the power splitting passive optical network, without having passed through a power splitter. At least one reflector and/or refractor in the housing is oriented to reflect and/or refract at least one upstream optical signal from at least one of the drop optical fibers, so as to produce the aggregate upstream optical signal for the trunk optical fiber. Various configurations of reflectors and/or refractors may be provided. Relative methods are also disclosed.

    摘要: A Gigabit-capable Passive Optical Network (GPON), including an enhanced Optical Line Termination (OLT) and Optical Network Units (ONUs), provides enhanced features, e.g., features defined in XG-PON. One or more of the ONUs are enhanced ONUs. The enhanced OLT communicates with the ONUs via downstream frames and upstream bursts, each downstream frame and upstream burst being compliant with a GPON framing format. The enhanced OLT transmits downstream frames to the ONUs, the downstream frames including downstream sub-frames with at least one downstream sub-frame being an overhead sub-frame that includes information of the enhanced features. The enhanced OLT receives upstream bursts from the ONUs, the upstream bursts including upstream sub-frames, each upstream sub-frame including an upstream identifier field that indicates to the enhanced OLT whether the upstream sub-frame is an overhead sub-frame. The enhanced OLT and the enhanced ONUs perform network operations to provide the enhanced features specified in the overhead sub-frame.

    摘要: Method and arrangement for protecting optical network systems, the arrangement (20) is based on an optical electrical optical GPON repeater structure. The repeater structure contains two optical modules—a regular ONU transceiver module and a reset-less OLT transceiver module which are working back-to-back. For management purposes, an ONU MAC module comprised in the repeater structure is intercepting the electrical signals from the ONU transceiver. The arrangement comprising the two repeater structures can be used to relay data between two passive optical network (PON) systems thereby opening a way to implement dual homing via the PON domain. Moreover, the arrangement is configured to enabling switch-over of functionality from one PON to the other PON at a communication failure in the former PON.

    摘要: When data containing an unrecoverable error is received, instead of discarding the data, a lower protocol layer delivers the data to a higher protocol layer along with an indication that the data contains an error. The higher protocol layer parses the data to recover portions that are not affected by the error. Additionally, the higher protocol layer can choose to accept the data if certain acceptance criteria are met.
