A novel software architecture protocol stack with embedded routing algorithms under the Internet Protocol (IP) routing layer in order to provide high quality distribution of multimedia (voice, video, and data) services. These routing algorithms may include Logical Link Control, Adaptive Transmission Protocol, Neighbor Discovery, Traffic Control, Ad-Hoc Routing, Flow Processing, Intelligent Access and Admission Control. These routing algorithms when implemented further provide for advantages in speed of service, reliability of service, self-healing in case of catastrophic failure of an infrastructure component, load-balancing and geographic reuse.

Methods, apparatuses, computer program products, devices and systems are described that carry out accepting at least one telephone communication from at least one member of a network; disambiguating the at least one search term including associating the at least one search term with at least one of network-participation identifier data or device-identifier data; and presenting the sender profile in association with the at least one telephone communication.

Computational systems and methods for identifying a communications partner

A method and associated systems for enhanced isolation and security hardening among multi-tenant workloads. An agent running on a processor of a networked computer system on which multicast and broadcast communications have been disabled captures an address-resolution query message from a querying tenant, converts the query message to a unicast message, and forwards the converted unicast query message to a switch. The switch forwards the converted unicast message to a redirection device and in response receives an address-resolution response message only after the redirection device verifies that the query and response messages comply with security policies. The switch forwards the address-resolution response to the querying tenant in conformance with security policies.

Isolation and security hardening among workloads in a multi-tenant networked environment

In one embodiment of the method, a channel quality metric for a first subframe is estimated based at least in part on a channel quality metric for a previous subframe, and a channel quality metric for a second subframe is estimated based at least in part on the channel quality metric for the previous subframe. Here, the second subframe is later in time than the first subframe. Then, a channel quality metric for a time slot located between the first and second subframes is estimated based on the channel quality metrics for the first and second subframes.

An apparatus that includes a coupling, a signal level measurement circuit, a communication circuit and a processing circuit. The coupling is configured to connect to and received broadband RF signals from a coaxial cable termination of a communication network. The signal level measurement circuit is operably coupled to the coupling, and is operable to generate signal level measurements regarding a first set of the broadband RF signals. The communication circuit operable to obtain voice over internet protocol data packets from a second set of broadband RF signals. The processing circuit is operably connected to the communication circuit, and is operably connected to receive signal level measurements from the signal level measurement circuit. The processing circuit is operable to obtain diagnostic data relating to the second set of broadband RF signals. The processing circuit is further operable to cause communication of information representative of the signal level measurements and the diagnostic data in human-perceptible form.

Signal level measurement and data connection quality analysis apparatus and methods

A method and signal therfor embodied in a carrier wave for sending information from transmit stations to receive stations over a transmission medium of a frame-based communications network. The information is sent in transmit frames having a frame format comprising a fixed rate header, followed by a variable rate payload, followed by a fixed rate trailer. The fixed rate header includes a preamble. The preamble has a repetition of four symbol sequences for facilitating power estimation, gain control, baud frequency offset estimation, equalizer training, carrier sensing and collision detection. The preamble also includes a frame control field. The frame control field has scrambler control information for frame scrambling initialization, a priority field to determine the absolute priority a transmit frame will have when determining access to the transmission medium, a payload encoding field which determines constellation encoding of payload bits in the variable rate payload, and a header check sequence for providing a cyclic redundancy check. The variable rate payload is transmitted pursuant to dynamic adjustable frame encoding parameters for improving transmission performance for a transmit frame being transmitted from a transmitting station to a receiving station. The header also includes a destination address field, a source address field and an ethertype field.

Methods and systems for generating anonymous MAC addresses and determining permanent MAC addresses from anonymous MAC addresses are disclosed. Permanent MAC addresses may be associated with a location in a location database. Generating anonymous MAC addresses may protect user privacy and allow manufacturers and users of wireless access points to control their inclusion in location databases.

Frame-based communication with variable rate payload

Systems and methods for providing dynamic substream definition and handover are provided. In embodiments, a user device includes a multiple radio access technology (RAT) communications modules and a communication controller. Each RAT communication module is further configured to communicate using a different RAT. The user device identifies available networks for communication. Then, the controller determines whether a need to split a communications stream exists (e.g., the user device is engaged in a bandwidth intensive application). If the communications stream is to be split, the controller defines the substreams (either equally or unequally) and assigns a first substream to a communication pathway in a first available network and assigns a second substream to a communication pathway in a second available network. The destination then recombines the substreams. In embodiments, the controller inserts synchronization in the substreams.
