Abstract: A method, system and computer program product for backup assignment of a mobile electronics device is disclosed. In response to one or more device assignment requests received by a controller apparatus when a server is operating in an off-line mode, one or more device assignment records are created within the controller apparatus, and which indicate assignment of the at least one mobile electronics device to a respective one or more users. When the server is operating in an off-line mode such that communication between the controller apparatus and the server is off-line, the one or more device assignment records, in relation to the at least one mobile electronics device, are stored in the controller apparatus. In response to the server re-entering the on-line mode, the server is updated with the one or more device assignment records.

Abstract: A synchronization scheme is provided that includes querying a managed device to obtain an initial device state, synchronizing the device state in a plurality of management processes, detecting a change in the initial device state, and maintaining a synchronized current device state between the managed device and the plurality of management processes.

Abstract: A method and system include collecting information in a network device, determining in the network device when to send a subset of the collected information to a collection system, and determining in the network device a subset of the collected information to be transmitted at a given time.

Abstract: Methods and apparatus for collecting, storing, processing and using data are described. Network traffic probes are identified and attempts are made to configure the probes to generate network traffic data sets which are as close to a preselected common data format as possible. Application layer traffic data is collected in addition to network layer traffic data. The common data format uses delta count values, and terminal count mode format. Network data is obtained from a probe using one of the available table formats which is selected in the following order of preference: alMatrixTopN (Terminal Mode), alMatrixTopN (AllMode), alMatrix, nlMatrixTopN and nlMatrix. A database of collected network traffic information which includes multiple parallel sets of data stored at different resolutions is created. The data sets for each individual resolution are stored in a separate FIFO data structure and the oldest data records are overwritten when allocated data space becomes fully utilized.

Abstract: Methods and apparatus for collecting, storing, processing and using data, such a RMON2 network traffic data, are described. Network traffic probes are identified and attempts are made to configure the identified probes to generate network traffic data sets which are as close to a preselected common data format as possible. Application layer traffic data is collected in addition to network layer traffic data when possible. In an RMON2 embodiment, the common data format includes the use of delta count values as opposed to absolute count values. The common data format of the present invention utilizes terminal count mode format as opposed to all count mode format for the presentation of RMON2 application layer information. To minimize the amount of data processing required to put a probe's network traffic data into the desired common format and to maximize the amount of information collected, network data is obtained from a probe using one of the available RMON2 table formats.

Abstract: A high impedance tap for monitoring traffic over a communication link of a fast Ethernet local area network (LAN). The circuit of the present invention is advantageously used for tapping into a fast Ethernet communication link (e.g., bi-directional communication channel) of a LAN using, for instance, {fraction (10/100)} BaseT Ethernet communication protocol. The novel circuit is particularly useful in point to point communication links (e.g., supporting fast Ethernet communication) where two communication nodes are coupled together using a bi-directional communication link (e.g., two twisted pair cables). Unlike the prior art monitoring probes, the probe of the present invention does not insert itself in series between the communication link, but rather taps onto the communication link in parallel using a high impedance termination circuit thereby leaving the existing communication link undisturbed electrically.

Abstract: Disclosed are a method and apparatus for collecting network data from a computer network. Control structures are created for groups of data to be collected. The control structures are then associated with corresponding tables for storing the data. Different control structures and extract functions are defined depending upon which data is to be collected, and the form in which the data is to be presented. These control structures and extract functions are then employed to avoid redundant data gathering efforts.
