A communication method is provided in a communication network, including a plurality of devices forming an ordered communication segment. At least one intermediate device of this segment is connected to at most two other devices called a previous device and a next device. The intermediate device receives data from the previous device and emits at least these data to the next device to propagate the data on the segment. A concentrator initializes transmission of a first frame of data through the segment to a terminal device ending the segment, which sends back a symbol initiating transmission of a second frame of data to the first concentrator through the segment. The method includes receiving a first symbol from the previous device, which triggers emitting a WAIT symbol to the previous device and emitting at least first symbol to the next device.

Methods, systems, and devices for determining a subset of user devices from among a complete set of user devices based on a set of received information, i.e., attributes, associated with a photograph or user device that transmitted the photograph and attributes, where the disposition of the information may be used to determine the subset and then perform facial recognition check on the subset of user associated photographs in order to accurately identify each user or users present in the photograph.

The present invention provides a methods, apparatus and systems for improving a systems-level data rate on a communications link such the orthogonal frequency division multiplexed multiple access (OFDMA) downlink used in used in WiFi and LTE cellular/wireless mobile data applications. The present invention preferably uses a form of multilevel coding and decoding known as tiled-building-block encoding/decoding. With the present invention, different receivers coupled to different parallel downlink channels with different channel qualities decode different received signal constellations at different levels of resolution. This allows the downlink of the OFDMA system to operate with a significantly higher data rate, thus eliminating existing inefficiencies in the downlink and significantly increasing system level bandwidth efficiency.

A flow management method comprises receiving (210) of incoming downlink packets. The received downlink packets are classified (220) in sub-flows, based on information that is available in a header of respective such received downlink packet. The downlink packets of each sub-flow are queued (230) in a respective sub-flow queue. Downlink packets are extracted (250) from the sub-flow queues into a common outgoing flow. A sub-flow queue from which no downlink packets yet have been extracted is prioritized (240). The extraction comprises assigning of an indicator of last service occasion to each sub-flow queue when a predetermined amount of data has been extracted from said sub-flow queue. When no prioritized sub-flow queues are present, the sub-flow queue with the earliest last service is selected. When a prioritized sub-flow queue is present, the prioritized subflow queue is selected. The downlink packets of the common outgoing flow are sent (260).

A method of configuring at least one switch involves configuring the at least one switch to direct communication to at least one of a plurality of computers according to at least one outcome of simulated interaction of a plurality of virtual network routers. A method of simulating interaction of a plurality of virtual network routers involves: causing a first at least one processor circuit to simulate the interaction of the plurality of virtual network routers; and causing a second at least one processor circuit, different from the first at least one processor circuit, to simulate the interaction of the plurality of virtual network routers redundantly to the simulated interaction of the plurality of virtual network routers on the first at least one processor circuit. Apparatuses and computer-readable media are also disclosed.

A technique for differentiation controllers and reconcilers for software operators in a distributed computing environment is described herein. In one example of the present disclosure, a system can include a node of a distributed computing environment that includes a container configured to execute a controller associated with a software operator. The controller can determine a reconciler that is associated with the container, detect an event that is associated with the reconciler, and invoke the reconciler via a selected communication protocol. The system can include the reconciler configured to process the event in response to being invoked by the controller and to provide a response associated with the event to the controller via the selected communication protocol.

A device may receive network protocol data identifying a network protocol trace associated with network devices of a network, and may divide the network protocol trace into multiple segments. The device may identify a set of segments, in the multiple segments, that includes a first segment and second segments related to the first segment, and may process the multiple segments, in parallel, to determine first results data corresponding to the multiple segments. The device may process the second segments, in parallel, to determine second results data, and may combine the first results data and the second results data to generate final results data, wherein the final results data indicate utilization by the network devices of a network protocol associated with the network. The device may perform one or more actions based on the final results data.

Signalling messages in an Internet Protocol, IP, communications network comprising a chain of at least two entities applying object oriented processing of signalling messages are exchanged between the at least two entities of the IP communications network comprising object oriented based data items. Parsing and inverse parsing of text based signalling messages are effectively avoided, thereby reducing system resources and increasing processing speed of the system as a whole.

A system may include a processor and packet controller logic circuits implementing a distribution module, packet processing paths each including at least one configurable parsing engine and concatenating module pair, and an aggregation module. The distribution module can distribute an information unit between the plurality of packet processing paths. At least one of the packet processing paths can include multiple configurable parsing engine and concatenating module pairs coupled sequentially, and at least a portion of the information unit can be processed sequentially by the multiple configurable parsing engine and concatenating module pairs. The aggregation module can collect outputs from the packet processing paths.

A method for visualizing interdependent network protocol fields for fuzzing and progress reporting includes providing a graphical user interface including a stacked representation of network protocol fields to be fuzzed. The method further includes displaying, in the stacked representation, an indication of network protocol fields that can or cannot be fuzzed. The method further includes receiving, via the stacked representation, selections of network protocol fields to be fuzzed and specifications of fuzzed parameter values for the selections. The method further includes generating and sending to a device under test network protocol packets with fuzzed parameter values according the selections and specifications.
