A method is presented for determining optimal or preferred configuration settings for wireless or wired network equipment in order to obtain a desirable level of network performance. A site-specific network model is used with adaptive processing to perform efficient design and on-going management of network performance. The invention iteratively determines overall network performance and cost, and further iterates equipment settings, locations and orientations. Real time control is between a site-specific Computer Aided Design (CAD) software application and the physical components of the network allows the invention to display, store, and iteratively adapt any network to constantly varying traffic and interference conditions. Alarms provide rapid adaptation of network parameters, and alerts and preprogrammed network shutdown actions may be taken autonomously. A wireless post-it note device and network allows massive data such as book contents or hard drive memory to be accessed within a room by a wide bandwidth reader device, and this can further be interconnected to the internet or Ethernet backbone in order to provide worldwide access and remote retrieval to wireless post-it devices.

Distributed remote monitoring (dRMON) of network traffic and performance uses distributed nodes to collect traffic statistics at distributed points in the network. These statistics are forwarded to collectors which compile the statistics to create combined views of network performance. A collector may mimic a prior art, non-distributed, network probe and may interact with network management software as though it were a stand alone network probe thereby simplifying a user's interaction with the distributed system. The invention is designed to work in accordance with a variety of standard network management protocols including SNMP, RMON, and RMON2 but is not limited to those environments. The invention has applications in a variety of communication system environments including local area networks, cable television distribution systems, ATM systems, and advanced telephony systems. A specific embodiment of the invention solves is particularly optimized to work in LAN environments with end systems running under Windows-compatible network operating systems.

A system and method for estimating the position of wireless devices within a wireless communication network combines measured RF channel characteristics for the wireless device with one or more predicted performance lookup tables, each of which correlates an RF channel characteristic to some higher order network performance metric and/or a position within an environmental model. Measured RF channel characteristics for wireless devices are compared against the performance lookup tables to determine the sent of lookup tables that most closely match the measured RF channel characteristics. The positions within the environmental model corresponding to the selected set of matching lookup tables are identified as possible locations for the wireless device. The performance lookup tables are uniquely constructed by site-specific location, technology, wireless standard, and equipment types, and/or the current operating state of the communications network.

A method and apparatus for the distributed monitoring of network traffic deploys end system agents to collect traffic statistics at distributed points in the network. These statistics are forwarded to collectors which compile the statistics to create higher level pictures of network performance. A collector may act as a proxy for a prior art standalone network probe and may interact with network management software as though it were a standalone network probe. The invention is designed to work in accordance with a variety of standard network management protocols including SNMP, RMON, and RMON2 but is not limited to those environments.

A Domain Name System (DNS) server is configured for dynamically selecting, for a client device, a selected resolution from available resolutions, the selected resolution identifying at least one destination for the specified service. The dynamic selection of the selected resolution is based on an attribute of the client device and/or a determined attribute of the network. Hence, the selected resolution directs the client device to a specific server based on prescribed selection criteria, for example service level agreements, the location of the client device, network performance or detected congestion conditions, authentication of the user of the client device, etc. The selected resolution also can be for enforcement of load balancing policies.

A method and system for identifying causes of performance metric changes in a network by selecting, from a pool of network event counters, a plurality of candidate counters relevant to a performance metric; grouping the candidate counters into clusters of similar counters; selecting, from each cluster, one or more representative counters; and fitting the selected representative counters to a model of the performance metric to determine thereby a set of representative counters most relevant to the performance metric.

An automated meter reading network system to collect utility usage data from multiple utility meters having utility meter sensors, program product, and associated methods are provided.

The present invention makes it possible to obtain debug- and other diagnostic information from mobile electronic devices in a system operator network. A Log Management object provides support for logging diagnostic data. A log file is employed to collect information on various device features for which tracing or debugging is turned on in a mobile electronic device such as, for example, a mobile handset, cellular phone, a personal digital assistant, a pager and a personal computer. It is also used to selectively collect information on specific events that are monitored, device specific data being collected, and network performance data, among other items. The diagnostic agent in the mobile device is a client side application that may run on the mobile device when required, or continuously as a monitoring application, and which manages and collects tracing information wirelessly to a server using a cellular data network. A diagnostic client may also be downloaded and executed to collect diagnostic data from applications, for example. Traps may also be set and data collected from them. The Log file may be retrieved from the server side in pull or push mode.
