Embodiments described herein include systems, apparatuses, and methods for attempting to wirelessly communicate with a networkable device with a mobile device to retrieve an identifier for the networkable device; receiving the identifier from the networkable device; storing the identifier in the mobile device; and sending a request to a provisioning server to provision the networkable device.

Installation of networkable devices

Described herein are systems, methods, and apparatuses for device communication over IP. In some embodiments, IPv6 addresses are compressed into ISO/IEC 14908-1 addresses, and use leading zero suppression to compress the headers. In some embodiments, IPv4 the least significant two bytes of the IPv4 address are used as an ISO/IEC 14908-1 subnet and node number.

Systems, methods, and apparatuses using common addressing

An improved programming interface which provides for event scheduling, improved variable declarations allowing for configuration of declaration parameters, and improved handling of I/O objects. In modern day computing devices and especially in networks of such devices it is important to provide for event scheduling; known computing devices allow for event scheduling based on the occurrence of a predefined event. However, such a system present shortfalls in that flexibility is not provided to allow scheduling based on any arbitrary condition. Therefore, it is disclosed to provide a programming environment which allows for event scheduling where the event may be any arbitrary condition thus providing increased flexibility in event driven programs. In addition, programs which run on such computing devices typically declare one or more variables; such variables having one or more parameters associated therewith. These parameters are set to a state by the programmer, which state presumably is the state expected by the programmer to be the optimal state. The present invention provides flexibility in allowing such states to be changed, for example at the time a network implementing the computing device is configured. Additionally, it is disclosed to have improved declaration and control of I/O devices providing for ease of use and flexibility.

Task scheduling in an event driven environment

Method and apparatus for treating a logical programming expression as an event in an event-driven computer environment

An improved apparatus and method for communicating information in a networked system wherein network variables are employed to accomplish such communication. Network variables allow for standardized communication of data between nodes in a network. A first node may be programmed, for example, to sense certain information and to report the information as a network variable X. A second node may be programmed to receive the variable X and to control devices based on the current value of the variable. The present invention provides for defining connections between the first and second node to facilitate such communication and for determining addressing information to allow for addressing of messages, including updates to the value of the variable X, between the nodes.

Method for enhancing the performance of a network

A method of determining a transaction identifier for a message to be sent from a node on a network. The node has an address table and a memory. The method comprising the steps of: accessing the address table to determine an address for the message; and accessing the transaction identifier at a memory location corresponding to the address.

Networked variables

In a communications system, an apparatus and method for detecting a valid signal from noise. An adaptive threshold is used to qualify a received signal. The adaptive threshold is set according to the number of false detects occurring within a given time interval. The number of false detects is initially determined by a quick qualification process. This initial number is subsequently adjusted by a more accurate qualification process. The transmitted signal is modulated with a particular pattern. Upon receiving the signal, it is demodulated to retrieve that pattern. The demodulated pattern is correlated against multiple reference patterns and combined to provide a measure of peak correlation that is independent of pattern phase. Furthermore, a tone detector is used to distinguish valid signals from interfering tones. Two different types of detection methods are performed in parallel. One is based on the energy of the received signal, whereas the other is based on the correlation of the received signal.

Apparatus and method for detecting a signal in a communications system

An apparatus and method for network node identification and network configuration. Prior to physical installation, a first node of a network is communicated with by a dedicated apparatus wherein the first node is requested to transmit a first unique identifier for the node to the apparatus. The apparatus then stores the first unique identifier received from the first node, and generates the first unique identifier on a medium (e.g. a label). This first unique identifier may be represented on the medium in a coded format. In one embodiment, the coded format is a code 39 bar code and the medium is an adhesive label. The labels obtained from querying the nodes prior to physical installation may be affixed to a floor plan of a networking system during installation, indicating each node's physical placement in that system. Each of the identifiers may then later be automatically read by an automated apparatus for network configuration. This apparatus (e.g. a general purpose programmed computer system) displays a physical layout of the networking system. This apparatus automatically reads the labels comprising the unique identifiers of nodes and assigns the identifiers to the respective positions on the physical layout of the networking system according to the position of the nodes on the diagram. Each of the codes, in a preferred embodiment, are associated with the physical placement of node in the networking system by a floor plan displayed on a display device (e.g. a CRT). Then, nodes in the system may be configured (by grouping, network address assignment, etc. . . . ) to communicate with other nodes in the network via the communication medium which is represented on the floor plan.

System for installing and configuring (grouping and node address

Method and apparatus using network variables in a multi-node network

An apparatus useful in the configuration of communication network. The present invention provides for improved apparatus and techniques for configuration of network nodes. In particular, what is described is a device which may be coupled with each node of a network. When coupled to a node, the device and node cooperate in allowing communication of information identifying the node and the node type to the device. The node identification and type information may then be utilized to reliably complete configuration of a network.

Configuration device for use in a networked communication system

An improved apparatus and method for routing of messages in a networked system wherein reduced unnecessary retransmission of messages across routers is achieved by examining the address of the source of messages to be forwarded and, if the source of the message is on the transmit side of the router, not retransmitting the message. Further, when messages are originated which do not include source subnet address information, a router receiving such a message will update the source subnet address field of the message with its own source subnet address so as to allow other routers to use the updated source subnet address information in making routing decisions.

Method and apparatus for preventing unnecessary retransmission of

An improved network for communication of message packets. The network of the present invention implements an improved collision avoidance, detection and backoff system for communication on a media between nodes. The apparatus calculates a time period P after detecting the media is idle using a formula F which is a function of a pseudo-random delay factor T. If the media remains idle during the time period P, the device may transmit a message. The apparatus further has the ability to assign messages as being either priority or non-priority messages. Priority messages may be transmitted during priority message slots preassigned to transmitting nodes. Non-priority message contend for the media during a period of time following the period set for transmission of priority messages.

Multiaccess carrier sensing network communication protocol with priority

An improved network for communication of message packets. The present invention provides for improved reliable multicast messaging wherein messages may be reliably multicast to members of a multicast group and acknowledgements may be handled in an improved and efficient manner. In particular, a message may be transmitted to all members of a group, each member of the group responding to receipt of the message with an acknowledgement message. Further, facility is provided to allow for transmissions of reminder messages in the event one or members of a group do not respond to a message with an acknowledgement.
