Abstract:

A system, apparatus, and method for network traffic management. The method includes establishing a building zone corresponding with a physical space in the building, determining how many networked devices are in the building zone, determining a current multicast use level, establishing a virtual group threshold based on a current portion of a network multicast capacity that is being used, and unicast transmitting a message to a plurality of networked devices in the building zone when the number of networked devices in the building zone is less than the virtual group threshold.

Assignee:

California Eastern Laboratories, Inc. - Santa Clara CA

International Classification:

H04L 12/841
G06F 9/30

Abstract:

A system, apparatus, and method for network traffic and processor activity management. The invention includes a network communication device for communicating data to remote devices, a data storage device for storing a plurality of messages to be communicated on the network by the network communication device, a real-time clock, and a processor. The processor includes instructions which, when executed by the processor, cause the processor to receive a signal from the real-time clock that at least one message in the data storage device is to be communicated on the network through the network communication device, retrieve the at least one message from the data storage device, transmit the at least one retrieved message and up to a predetermined number of retrieved messages onto the network through the network communication device, and prevent any messages retrieved from the data storage device that are more than the predetermined number from being transmitted on the network for a predetermined period of time.

International Classification:

H04L 12/28

H04W 76/02
H04W 88/16

Abstract:

Systems and methods are disclosed for interleaving communications with a home area network (HAN) and a data network. A gateway device interleaves communications within timeslots of a time slotted channel hopping protocol. A gateway device can be configured to determine, during a first portion of a timeslot, whether the gateway device received a portion of a message from a data network. If the gateway device receives no messages from the data network during the first portion of the timeslot, the gateway device switches to listen for communication from the HAN during a second portion of the timeslot. If the gateway device receives a portion of the message from the HAN, the gateway device continues to receive receives the remainder of the message until one or more trigger conditions that cause the gateway device to listen for communication from the data network.

Appl. No.:

Inventors:

- Alpharetta GA, US
James Hartman - Canton GA, US

International Classification:

H04W 56/00

Abstract:

Disclosed are various embodiments for optimizing network event timers for a node. The node obtains data for transmission by the node via a network. The node uses time intervals of a clock as a basis for determining actions associated with the network. A transmission duration is calculated that corresponds to the time for transmitting the data via the network based on a data rate of the network and a size of the data. The node calculates a transmission delay based on the transmission duration. The transmission delay is less than a clock interval and controls when transmission of the data is completed by the node. After the expiration of the transmission delay, the node transmits the data via the network. The node initiates an event timer when the transmission is completed, where the event timer measures time based upon counting the time intervals elapsed since the event timer began.

- Alpharetta GA, US
James Hartman - Canton GA, US

Assignee:

Landis+Gyr Innovations, Inc. - Alpharetta GA

International Classification:

H04B 1/69

Abstract:

Systems and methods are provided for adjusting time in a synchronized network by a central device on the network. Each device on the network provided current time, hopping pattern, time slot duration, and an absolute slot number. Devices on the network synchronized to communicate on a repeating schedule of time slots. The central device receives an updated time and determines a time difference between the updated time and the current time. The current time is adjusted in integer multiples of the hopping pattern length up to the time difference. The absolute slot number is updated based on the number of time slots in the adjusted time difference. The updated absolute slot number is propagated to other devices on the network. In turn, these other devices may also propagate the updated absolute slot number.
