In some examples, a software-defined network (SDN) controller determines a link aggregation (LAG) configuration for a node in the SDN that is controlled by the SDN controller. The LAG configuration is based on hardware capability information and dynamic network traffic information of the SDN. The SDN controller can further instruct the node to forward traffic in accordance with the LAG configuration.

A receiver node receives, over a communication fabric, a transaction packet that includes an identifier of a sender node and an identifier of a process at the sender node, the transaction packet sent by the process for a transaction. The receiver node performs authentication for the transaction based on the identifier of the process and the identifier of the sender node.

The present disclosure is directed to an input/output module. In some embodiments, the input/output module includes: a plurality of communication channels, each channel of the plurality of communication channels configured to connect to one or more field devices; switch fabric configured to selectively facilitate connectivity between an external control module and the one or more field devices via the plurality of communication channels; a serial communications port configured for connecting the input/output module to the control module in parallel with a second input/output module, the serial communications port configured for transmitting information between the input/output module and the control module; and a parallel communications port configured for separately connecting the input/output module to the control module, the parallel communications port configured for transmitting information between the input/output module and the control module, and transmitting information between the input/output module and the second input/output module.

An NFA hardware engine includes a pipeline and a controller. The pipeline includes a plurality of stages, where one of the stages includes a transition table. Both a first automaton and a second automaton are encoded in the same transition table. The controller receives NFA engine commands onto the NFA engine and controls the pipeline in response to the NFA engine commands.

A control system 9 according to the present invention is mounted on a moving object. The control system 9 includes: an observing device 92 which transmits observation result data indicating an observation result of surroundings of the moving object; a first control instruction device 91 which transmits first control data indicating the control contents determined based on the observation result data; a movement control device 93 which controls movement of the moving object; and a relay device 95 which relays the first control data transmitted from the first control instruction device 91, to the movement control device 93. When a second control instruction device 94 which transmits second control data indicating the control contents determined based on the observation result data is provided to the control system 9, the relay device 95 transmits the second control data instead of the first control data, to the movement control device 93.

A telecommunication system employs dynamic shaping across a plurality of access modules of an access node using a dynamic bandwidth allocation (DBA) algorithm that is based on current load conditions for each of the access modules in order to achieve a fair allocation of network bandwidth at the access node. In one exemplary embodiment, access modules at an access node communicate via a control channel with shaper control logic that receives load information from each of the access modules. Using such load information, the shaper control logic dynamically controls the shaper rates for the access modules so that a fair allocation of network bandwidth is achieved across all of the access modules. Specifically, the shaper rates are controlled such that packet flows for services of the same class achieve the same or similar performance (e.g., average data rate) regardless of which access module is communicating each respective packet flow.

A cable signal detector for being provided at a connector at an end of a communication cable transmitting differential signals or at a relay connector to be connected to the connector to detect an existence of information communication. The cable signal detector includes an amplifier circuit that branches and extracts a portion of a signal transmitted through the communication cable, amplifies the extracted signal and outputs the amplified signal, and a display portion that display the existence of information communication based on the output of the amplifier circuit. The amplifier circuit is mounted on a detection device formed separately from the connector or the relay connector. The connector or the relay connector is configured to transmit the extracted signal to the detection device.

Embodiments of the invention are directed to communication systems and methods that allow a resident of a controlled environment facility to report a past, on-going or threatened crime, such as a rape. The resident is able to make the report using a facility communications system without alerting other residents of the controlled environment facility that the crime has been reported.

The present invention provides a method and an apparatus for data packet switching, and an access switch and a switching system, so as to satisfy requirements of a datacenter for a switching bandwidth and a switching granularity. The method includes: receiving MAC frame control information; determining an interface used for forwarding an MAC frame according to the MAC frame control information and through performing a query on a MAC address forwarding table, where the interface used for forwarding the MAC frame includes a downlink interface, an uplink electrical packet switching network interface and/or an uplink optical packet switching network interface; transmitting a control signal to an electrical packet switching unit, so that the MAC frame is forwarded to the determined interface. According to the method provided in the present invention, the utilization rate of each interface can be improved.
