System and methods for locating events and/or devices on a network are described.

System and method for locating events and/or devices on a network

Systems and methods for improved geolocation in a low power wide area network are disclosed. One example method may include receiving an instruction to determine a geolocation of an end in a low power wide area network. An instruction may be transmitted to the end node for the end node to transmit a high-energy geolocation signal at a power of about 0.5 Watt to about 1 Watt. The end node may transmit the high-energy geolocation signal and a plurality of gateways of the low power wide area network may receive the high-energy geolocation signal. A plurality of receipt times may be identified. Each receipt time may be indicative of the time at which the high-energy geolocation signal was received by the respective gateway of the plurality of gateways. Based at least in part on the plurality of receipt times, a geolocation of the end node may be determined.

A reduced-complexity Internet of Things sensor is disclosed. An example apparatus comprises memory storing one or more sensor event messages, a radio configured to determine a sensor event, a counter configured to output incremental counter states, and a control circuitry. The control circuitry may be in communication with the memory, the radio, and counter, and the sensor. The control circuitry may be configured to determine, based on the sensor event, a select sensor event message of the one or more sensor event messages. The control circuitry may be further configured to output, via the radio signal, a packet comprising the select event message and an indication of a counter state associated with the sensor event message.

Modern day user applications leverages new communication technologies such as WebRTC, WebEx, and Jabber allow devices to connect and exchange media content including audio streams, video streams, and data stream/channels. The present disclosure describes mechanisms for a Port Control Protocol (PCP) server to provide feedback to PCP clients to enforce certain policies on the transport of such media content for a network. A policy may include a traffic handling policy for enforcing differentiated quality of service characteristics for different types of media streams. Another policy may include a security policy ensuring a data files being transmitted over a data channel from one endpoint travels to a security application via a relay element before the packets reaches another endpoint. The mechanisms are transparent to the endpoints, and advantageously preserve the user experience for these user applications.

Smarter policy decisions based on metadata in data flows

According to one configuration, a wireless communication system includes one or more wireless communication devices and gateway hardware. The gateway hardware can be configured to notify the one or more wireless communication devices of a change associated with frequency hopping settings (such as switchover from first frequency hopping settings to second frequency hopping settings). Further, the gateway hardware can include a first radio frequency interface and a second radio frequency interface. In accordance with the frequency hopping settings, the gateway hardware: i) fixedly tunes the first radio frequency interface to a first wireless channel; and ii) while the first radio frequency interface is fixedly tuned to the first wireless channel, the gateway hardware dynamically tunes the second radio frequency interface to hop amongst multiple different wireless channels. The frequency hopping settings support different wireless power levels depending on a number of pseudorandom wireless channels that are hopped.

Wireless system and device communication management

Systems and methods for effectuating communication in a low power wide area network using a mobile data-handling device are disclosed. A method may comprise moving a mobile data-handling device to a first position that is within communication range of an end node of a low power wide area network. The mobile data-handling device may receive a data packet from the end node and may move to a second position at which the mobile data-handling device connects to a data-receiving device. The mobile data-handling device may transmit, via the data-receiving device, the data packet to a computing system for further processing.

Embodiments include detecting an increase in delay of a flow assigned to a first queue of a network device, where the increase is sufficient to cause the flow rate of the flow to decrease if the flow is delay-sensitive. Embodiments further include determining whether an amount of bandwidth consumed by the flow decreases sufficiently after the increase is detected, and assigning the flow to a second queue based, at least in part, on determining the amount of bandwidth consumed by the flow does not decrease sufficiently. Specific embodiments include evaluating a series of two or more bandwidth measurements of the flow according to a bandwidth reduction measure to determine whether the amount of bandwidth consumed by the flow decreases by sufficiently. More specific embodiments include the first queue being configured to receive delay-sensitive flows and the second queue being configured to receive delay-insensitive nice flows.

Setting delay precedence on queues before a bottleneck link based on flow characteristics

A computer-implemented method includes sending a first request message to a first server associated with a first access network indicative of a request for an indication of whether the first server is configured to support prioritization of tunneled traffic, receiving a first response message from the first server indicative of whether the first server is configured to support prioritization of tunneled traffic, establishing one or more first tunnels with a security service when the first response message is indicative that the first server is configured to support prioritization of tunneled traffic, sending first flow characteristics and a first tunnel identifier to the first server; and receiving the first flow characteristics for each first tunnel from the first server at a first network controller. The first network controller is configured to apply a quality of service policy within the first access network for each tunnel in accordance with the flow characteristics.

Differentiated quality of service using tunnels with security as a service

In one embodiment, a method comprises receiving a stream of transport packets encapsulating media packets, and generating a reference to the point-of-interest media packet relative to the location of the point-of-interest within the transport packet stream. The reference is generated for each media packet that is identified as a point-of-interest.

Locating points of interest using references to media frames within a packet flow

In one embodiment, characteristics of a connection traversing a packet switching device is determined, which includes, but not limited to, determining a network port number and/or address of an established connection based on a signature of the connection. In one embodiment, a packet switching device receives and forwards packets of particular communication between a device and a remote node in a network. The packet switching device maintains information of the particular communication and identification data for use in subsequent identification of said particular communication. In response to receiving a communications information request specifying a signature related to said particular communications, the packet switching device prepares and sends a response, which typically includes matching the signature to said maintained identification data resulting in identification of said information including a characterization of said particular communications, and sending a reply including the characterization of said particular communications.

An example method for facilitating on-demand bandwidth provisioning in a network environment is provided and includes receiving a request from a client at a first network for accommodating flow characteristics at a second network that is associated with executing an application at the first network, determining that the request cannot be fulfilled with available network resources allocated to the client by the second network, advising the client of additional cost for accommodating the flow characteristics, and authorizing additional network resources in the second network to accommodate the flow characteristics after receiving notification from the client of payment of the additional cost.
