An environmental control system controls monitoring and operation of a multiplicity of disparate environmental control devices by determining an appropriate configuration for each control device and communicates corresponding monitoring and control commands to each device in accordance with its corresponding communication protocol over a selected I/O port. An operational instruction set includes a structural definition of an enterprise facility in which devices are defined by personality modules and communicate with a system host in accordance with a protocol defined in a protocol module. Facility implementation is defined by a node tree structure which collects suitable protocol nodes under a corresponding I/O interface port node. Device (personality) nodes are collected under corresponding protocol nodes, and data point nodes depend from their corresponding device nodes. Data points nodes are individually accessible by merely traversing the node tree using a URL-like notational structure, allowing off-site users to control and monitor environmental devices by issuing commands in the form of a URL.

A system and method is described for saving power in a wireless network, using a physical layer address filtering protocol based on a partial address subset of the complete destination MAC address. The system comprises a PHY layer filtering protocol for generating the partial address and writing the partial address into a PHY layer header portion (e.g., PLCP header) of a sending station, or reading the partial address from the PHY layer header portion upon transmission of each frame. A receiving station receives and decodes these PHY layer header portion bits, in accordance with the protocol, and compares whether the subset of bits match that of the stations' own partial address. If a station finds a match, the station then continues further decoding the frame at PHY layer and send the complete frame to the MAC layer for further processing. The stations that do not have a match will not activate their MAC layer components. Thus, the stations of the network will avoid wasting power decoding a significant portion of the complete frame of other stations of the wireless local area networks and unnecessary MAC layer processing. When group addressed, control/management frames or other such frames are detected at the sending station, the address filtering protocol may be “disabled” using a partial address containing a predetermined value (e.g., all zeros).

The technology in this application provides a method and apparatus for efficiently using common uplink radio resources, e.g. a common uplink enhanced-dedicated physical channel (E-DCH) resource. A UE releases a common E-DCH resource very quickly after a completed transmission. In addition or alternatively, a base station may release a common E-DCH resource configuration from the network side to free up common E-DCH resources for use by other UEs. A low overhead signaling scheme for quickly and effectively releasing of common E-DCH resources between a UE and a base station is also described. For example, existing signaling fields on protocol layer 2 (L2) or layer 1 (L1) may be used. In one preferred example embodiment, signaling fields already in use in a CELL_DCH service state are given a different meaning for UEs in a CELL_FACH service state so that common E-DCH resources are quickly and effectively released.

A network monitoring system that summarizes a plurality of data packets of a session into a compact session record for storage and processing. Each session record may be produced in real-time and made available during the session and/or after the termination of the session. Depending on protocols, a network monitoring system extracts different sets of information, removes redundant information from the plurality of data packets, and adds performance information to produce the session record. The network monitoring system may retrieve and process a single session record or multiple session records for the same or different protocols to determine cause of events, resolve issues in a network or evaluate network performance or conditions. The session record enables analysis in the units of session instead of individual packets. Hence, the network monitoring system can analyze events, issues or performance of the network more efficiently and effectively.

The present invention relates to a method for improved and efficient usage of radio network resources with regard to the transmission properties of applied communication channel types and total network load by means of using early indications on the uplink or downlink of requests to establish new communication connection or adjust parameter settings of already existing connections regading the expectable amount of additional traffic due to such a connection. Early indications are, e.g., information on protocol type, the kind of requested communication service, the profile of the user equipment that has sent the request, or traffic history. In response to such indications the inventive method can forward, e.g., an uplink request and at the same time initiate a channel type switching providing appropriate channel parameter settings or adjustments. In case of congestion control it is another possibility to delay or even suppress uplink requests.

According to one embodiment, a network architecture includes a plurality of application monitoring modules for monitoring network traffic data that store the data in meta-flow tuples with associated measures. The meta-flow tuples include a protocol dimension with a value corresponding to a leaf node in a protocol identifier array. The protocol identifier array represents a protocol tree structure based on a set of nodes with pointers to parent, sibling, and child nodes corresponding to the protocol tree. The pointers include protocol identifier values that correspond to memory offset values with respect to the array. For queried protocol dimensions, the protocol identifier array is used to traverse the protocol tree from the leaf node in the meta-flow to a matching node matching the queried protocol. If the queried protocol is found in the protocol lineage of the meta-flow, the measures for the meta-flow are used to satisfy the query.

A transport neutral technique allows an object manager to communicate with a CIM repository using any of a variety of protocols. The object manager software is independent of the transport mechanism used and need not be changed if the transport mechanism changes. A computer system to be managed includes a CIM object manager and any number of provider APIs that provide resource information about the computer system. A CIM repository stores classes and instances used by the object manager. A remote application computer runs a software management application that communicates with the object manager of the computer system using a local client API. A Repository API of the object manager includes an interface definition defining all methods called by the object manager. Also included is a protocol-specific class that implements the interface definition; there is a protocol-specific class for each protocol desired to be supported. Each class implements methods using a specific protocol. A factory class is executed when the object manager invokes a method call passing in a desired protocol parameter. The factory class creates a protocol-specific object of one of the protocol-specific classes depending on the protocol parameter. The object is returned to the object manager which executes one of its protocol-specific methods thus allowing communication to a repository using a protocol independent of the object manager.
