A method and system for dynamically wedging data received from one or more automatic data collection ("ADC") devices on an ADC device platform into a destination application based upon wedging criteria. A dynamic wedge receives data from one or more ADC devices and automatically wedges the data into applications based upon user-provided data characteristics or a predetermined set of rules. Applicable wedging criteria used to route data include those that are user-composed and those that pertain to firmware or software characteristics. The dynamic wedge may comprise an ADC data server, ADC device handlers, ADC protocol handlers, and a wedging grid for retaining wedging directives. The ADC data server receives wedging directives from local and remote client applications and stores the wedging directives in the wedging grid. When data arrives from an ADC device, the ADC data server analyzes the data to determine its characteristics. The ADC data server compares the identified characteristics against the wedging directives stored in the wedging grid. The ADC data server then determines for which clients a match has been found. For those clients for which a match has been found, the ADC data server then performs the wedging directive in order to dispose properly of the received ADC data.
A node management method and system that supports multiple SNMP agents in a single platform (e.g., a network element or node) with capability to include the AgentX standard. An SNMP master agent and one or more subagents are provided for managing the node, and use the AgentX standard for communication therebetween. At least a select portion of a MIB associated with the management functionality of the managed node is supported by an SNMP peer agent that is proxied via an AgentX subagent (PSA).
A high level transformation method and apparatus for converting data formats in the context of network applications, among other places. A flexible transformation mechanism is provided that facilitates generation of translation machine code on the fly. A translator is dynamically generated by a translator compiler engine. The translator compiler engine implemented according to the present invention uses a pair of formal machine-readable format descriptions (FMRFDs) and a corresponding data map (DMAP) to generate executable machine code native to the translator platform CPU. When fed an input stream, the translator generates an output stream by executing the native object code generated on the fly by the translator compiler engine. In addition, the translator may be configured to perform a bi-directional translation between the two streams as well as translation between two distinct protocol sequences.
The invention relates to a microprocessor-based decoder board for an optical reader having in one embodiment a plurality of imaging modules that provide frames of image data having a plurality of formats. In one method for operating the decoder board of the invention, and a multiple imaging module reader comprising the decoder board, a frame of image data captured by a selected imaging module is decoded. The decoder board determines the format of the frame of image data from information about which of the plurality of imaging modules provided the frame of image data or from information about the frame of image data, activates as necessary a command to prepare the decoder board to decode the frame of image data according to the format provided by the imaging module, and performs the decoding.
