The invention provides a system and method for remotely diagnosing and repairing a plurality of Automatic Data Collection (“ADC”) device platforms. A remote service technician utilizes a computing system having browsing software that communicates with a network of ADC platform devices. Diagnostic queries for particular ADC devices may be retrieved by the browsing software from a diagnostic server that sends Hypertext Mark-Up Language (“HTML”) documents, Dynamic Hypertext Mark-Up Language (“DHTML”) documents, and / or Extensible Mark-Up Language (“XML”) documents containing appropriate diagnostic applets. The remote technician sends diagnostic queries to a Simple Network Management Protocol (“SNMP”) master agent at the ADC device platform, and a translator translates the diagnostic queries sent to the ADC device platform into a format suitable for reception by its ADC devices in order to effect anomaly diagnosis and functionality restoration. Another translator translates data received from the ADC device into the SNMP format for transmission to the remote service technician in order for the remote service technician to perform diagnostic analysis. The SNMP master agent communicates with the remote computing system using the Transmission Control Protocol (“TCP”), the User Datagram Protocol / Internet Protocol (“UDP / IP”), and / or the User Datagram Plus Protocol (“UDP+”). The ADC platform device may also utilize a wireless communication system for communicating with the remote service technician.

A system and method enables cluster-wide management of backup operations issued by one or more backup managers to nodes of a cluster using a network management protocol, such as NDMP. An NDMP daemon executing on each node is extended to include a processing module and a backup module. The processing module interfaces with a backup manager to interpret the backup operation and, if necessary, forward (proxy) that operation to another NDMP daemon on another node of the cluster for processing in accordance with cluster's unified namespace.

A scalable flow monitoring solution takes in standard flow records exported from network devices such as routers, switches, firewalls, hubs, etc., and annotates the flow with additional information. This information is derived from a number of sources, including Border Gateway Protocol (BGP), Simple Network Management Protocol (SNMP), user configuration, and other, intelligent flow analysis. These annotations add information to the flow data, and can be used to perform value-added flow analysis. The annotated flow is then resent to a configurable set of destinations using standard flow formatting, e.g., Cisco System Inc.'s NetFlow, in one implementation. This allows the annotated flow to be processed and the enhanced information to be used by other flow analysis tools and existing flow analysis infrastructure.

The present invention provides improvements to load balancing by providing a load balancing solution that allows a user to select metrics, weights and thresholds from metrics collected or determined by a load balancing appliance as well as metrics obtained from another device, such as a server running the service. The systems and methods described providing a load balancing technique in which load balancing decisions can be made based on metrics known by another device monitoring such metrics. The load balancing appliance uses a network management protocol and communication model, such as a Simple Network Management Protocol (SNMP), to identify and collect metrics from a server, service or other device. These metrics are available on the load balancing appliance with appliance determined metrics. Via a configuration interface of the appliance, a user can select one or more appliance determined metrics and / or the metrics obtained via the network management protocol to determine the load of a service.

Methods, apparatuses and systems facilitating the management of wireless computer network environments and the detection of rogue and other devices that may affect the performance and / or security of the wireless computer network. The present invention enables accurate and cost effective WLAN airspace mapping. In one embodiment, the present invention allows any conforming access point the ability to routinely scan its airspace, collect data on all operating frequencies and report this information back to a management platform. In one embodiment, the management and reporting functionality described herein uses a standards-based vehicle, such as Simple Network Management Protocol (SNMP). In one embodiment, the present invention facilitates isolation of rogue wireless devices affecting the computer network environment and effective decision-making as to management of the detected device. The present invention also allows network administrators to optimize the configuration of the wireless network environment for performance and security.

A network controller having a multiprotocol bus interface adapter coupled between a communication network and a computer bus, the adapter including a predictive time base generator; and a management bus controller adapted to monitor and manage preselected components coupled with one of the communication network and the computer bus. The management bus controller is adapted to employ an Alert Standard Format (ASF) specification protocol, a System Management Bus (SMBus) specification protocol, an Intelligent Platform Management Interface (IPMI) specification protocol, a Simple Network Management Protocol (SNMP), or a combination thereof. The network controller also includes a 10 / 100 / 1000BASE-T IEEE Std. 802.3-compliant transceiver and media access controller coupled with the communication network; a buffer memory coupled with the MAC, wherein the buffer memory includes one of a packet buffer memory, a frame buffer memory, a queue memory, and a combination thereof; and a transmit CPU and a receive CPU coupled with the multiprotocol bus interface adapter and the management bus controller. The network controller can be a single-chip VLSI device in an 0.18 micron CMOS VLSI implementation.

Channel trending, including determining a number of viewers watching a multimedia program, is achieved in a digital television network. Cached multimedia frames that correspond to portions of the multimedia program are maintained, for example, on a device located on an edge (i.e., in a network edge device) of the digital television network. In response to a request from a client device (e.g., a set-top box) to receive the multimedia program, cached multimedia frames are fed from the edge device to the client device. Upon a seamless transfer or handoff resulting in a simulcast replicator or multicast replicator providing further portions of the multimedia program, a signal (e.g., a simple network management protocol TRAP statement) is sent to a viewership statistic server for incrementing a counter.
