METHOD AND APPARATUS FOR PROVIDING INFRASTRUCTURE PROCESSING AND COMMUNICATIONS
Method and apparatus for deploying infrastructure electronics. An electronics bay is amounted on a streetlight pole. Power from the streetlight pole is apportioned between a streetlight and a power converter that generates direct current power for the electronics. Electronics are installed onto/into the electronics bay and power delivered to an electronic element is metered.
Synchronizing playback by media playback devices
Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.
Overlay management protocol for secure routing based on an overlay network
A method for creating a secure network is provided. The method comprises establishing an overlay domain to control routing between overlay edge routers based on an underlying transport network, wherein said establishing comprises running an overlay management protocol to exchange information within the overlay domain; in accordance with the overlay management protocol defining service routes that exist exclusively within the overlay domain wherein each overlay route includes information on at least service availability within the overlay domain; and selectively using the service routes to control routing between the overlay edge routers; wherein the said routing is through the underlying transport network in a manner in which said overlay routes is shared with the overlay edge routers but not with the underlying transport network via the overlay management protocol.
DATA PACKET TRAFFIC CONDITIONING THROUGH A LOSSY DATA PATH WITH FORWARD ERROR CORRECTION
Embodiments herein disclose conditioning traffic through multiple data paths of a Software-Defined Wide Area Network (SD-WAN). Some embodiments include monitoring a path through an SD-WAN to reach a destination node, determining a quality score for packets to the destination node on the path, determining a link utilization for the path, sending a data packet sequence to the destination node on the path, generating a forward error correction (FEC) packet for the data packet sequence, and sending the FEC packet to the destination node on the path in response to the quality score being less than a quality threshold and the link utilization being less than a high utilization threshold.
IP Address and Routing Schemes for Overlay Network
A communication system includes multiple Point-of-Presence (POP) interfaces distributed in a Wide-Area Network (WAN), and one or more processors coupled to the POP interfaces. The processors are configured to assign to an initiator in the communication system a client Internet Protocol (IP) address, including embedding in the client IP address an affiliation of the initiator with a group of initiators, to assign to a responder in the communication system a service IP address, including embedding in the service IP address an affiliation of the service with a group of responders, and to route traffic between the initiator and the responder, over the WAN via one or more of the POP interfaces, in a stateless manner, based on the affiliation of the initiator and the affiliation of the service, as embedded in the client and service IP addresses.
Spreading and precoding in OFDM
A user equipment (UE) in a wireless network employs orthogonal polyphase codes for encoding data symbols to generate a set of coded data symbols, which are modulated onto Orthogonal Frequency Division Multiplex (OFDM) subcarrier frequencies assigned for use by the UE, and the resulting OFDM signal is transmitted to a base station in the wireless network. The orthogonal polyphase codes include pairs of orthogonal polyphase codes that are complex conjugates of each other.
Systems and Methods for "Machine-to-Machine" (M2M) Communications Between Modules, Servers, and an Application using Public Key Infrastructure (PKI)
Methods and systems are provided for supporting efficient and secure “Machine-to-Machine” (M2M) communications using a module, a server, and an application. A module can communicate with the server by accessing the Internet, and the module can include a sensor and/or an actuator. The module, server, and application can utilize public key infrastructure (PKI) such as public keys and private keys. The module can internally derive pairs of private/public keys using cryptographic algorithms and a first set of parameters. A server can authenticate the submission of derived public keys and an associated module identity. The server can use a first server private key and a second set of parameters to (i) send module data to the application and (ii) receive module instructions from the application. The server can use a second server private key and the first set of parameters to communicate with the module.
Prioritization for WLAN access for LTE managing WLAN connectivity
Aspects relate to a priority mechanism for prioritizing network identifiers, for example SSIDs. As described herein, a UE may obtain one or more network identifier sets, each of the one or more network identifier sets having one or more network identifiers for a first RAT and a priority level, determine one or more of the network identifier sets that are under control of a second RAT, and after the determining, manage connections to the first RAT based, at least in part, on the priority level of the network identifier sets.
System and method for applying CMTS management policies based on individual devices
At least one aspect is directed to managing policies to control network assets in real-time by dynamically enforcing policies based on a variety of detected conditions including service quality, subscriber usage, network performance, bandwidth, and events. The systems and methods described herein can enforce policy actions using the PacketCable Multimedia (PCMM) protocol, which is supported by Cable Modem Termination Systems (CMTS). The present solution can monitor IPDR usage data and SNMP network utilization data to determine conditions about the network and provide PCMM instructions to a CMTS to control network resources on an individual subscriber level. By providing PCMM instructions to a CMTS, the present solution can make service changes to individual modems without modifying the modem's configuration file, requiring a modem reboot, or the installation of additional hardware in the operator's network.
Systems and methods for traffic load balancing on multiple WAN backhauls and multiple distinct LAN networks
In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for traffic aggregation on multiple WAN backhauls and multiple distinct LAN networks; for traffic load balancing on multiple WAN backhauls and multiple distinct LAN networks; and for performing self-healing operations utilizing multiple WAN backhauls serving multiple distinct LAN networks. For example, in one embodiment, a first Local Area Network (LAN) access device is to establish a first LAN; a second LAN access device is to establish a second LAN; a first Wide Area Network (WAN) backhaul connection is to provide the first LAN access device with WAN connectivity; a second WAN backhaul connection to provide the second LAN access device with WAN connectivity; a management device is communicatively interfaced with each of the first LAN access device, the second LAN access device, the first WAN backhaul connection, and the second WAN backhaul connection; and the management device routes a first portion of traffic originating from the first LAN over the first WAN backhaul connection and routes a second portion of the traffic originating from the first LAN over the second WAN backhaul connection.
