摘要： Techniques for implementing traffic deduplication in a visibility network are provided. According to one embodiment, a packet broker of the visibility network can receive a control or data packet replicated from a core network. The packet broker can then apply a first stage deduplication process in which the packet broker attempts to deduplicate the control or data packet based on one or more interfaces of the core network from which the control or data packet originated, and apply a second stage deduplication process in which the packet broker attempts to deduplicate the control or data packet based on the content (e.g., payload) of the control or data packet.

摘要： The invention optimizes a VM (virtual machine) that configures a virtual network function. A virtual network function management apparatus obtains information related to performance of a physical machine allocated to the virtual network function. The virtual network function management apparatus transmits information related to the performance of the physical machine allocated to the virtual network function to a virtual machine that configures the virtual network function. The virtual network function management apparatus causes the virtual machine that configures the virtual network function to change a congestion determination threshold that is set to the virtual machine based on the performance of the physical machine.

摘要： A communication device (100) includes: communicator (101) that transmits a confirmation signal; and controller (102) that controls a DHCP server function, in which controller (102): transmits a first confirmation signal to an other communication device through communicator (101); starts the DHCP server function and transmits a second confirmation signal to the other communication device through communicator (101) when a first response signal is not received from the other communication device in response to the first confirmation signal; stops the DHCP server function when a second response signal is received in response to the second confirmation signal; and performs a transmission control of a third confirmation signal to the other communication device through communicator (101), based on the second response signal.

摘要： An automatic failure recovery system that, using machine learning, creates an operation procedure for recovering from a network failure or corrects the created operation procedure has a plurality of recovery tasks for recovering from the network failure; outputs failure data indicating network configuration information and failure information acquired upon occurrence of the network failure; selects an execution procedure of the recovery tasks, based on the failure data and a recovery model acquired in advance; executes the selected execution procedure when the network failure occurs; determines whether or not recovery from the network failure was achieved by the execution procedure; and notifies that the procedure is to be corrected, depending upon the result of the determination and a recovery level of the network failure.

摘要： The invention enables optimal selection of a physical machine that causes operation of a VM configuring a virtual network function. A virtual network function management apparatus includes: a physical machine candidate query part configured to query, when creating a virtual network function, about a physical machine candidate in which a virtual machine configuring a virtual network function can be deployed, with respect to a virtual infrastructure management apparatus that manages a virtual infrastructure configured by using 2 or more types of physical machine; a physical machine selection part configured to select a physical machine that can satisfy performance required by the virtual network function, from among physical machine candidates received from the virtual infrastructure management apparatus; and a virtual machine creation instruction part configured to instruct the virtual infrastructure management apparatus to specify the selected physical machine and create a virtual machine configuring the virtual network function.

摘要： A wireless communication method and protocol for wireless RF transmission of data, e.g. audio data, with low latency. The method involves a fixed part (FP) serving as synchronization master, and one or more portable parts (PP) being synchronization slaves. The FP performs scanning between a set of supported channels within one limited frequency band, such as within an ISM band. Further, the FP performs collecting measures of RF interference level on at least a plurality of the supported channels in response to the scanning, preferably using own interference level measurement and by collecting RSSI data from the PP for the supported channels. In response to these measures of RF interference level, the FP executes a selection algorithm for selecting and re-selecting first and second different frequencies for respective first and second duplex RF bearers from the set of supported channels to select the channels with least RF interference. Finally, the FP transmits, in one frame of such as 1 ms to 3 ms length, the same data packet on both of said first and second duplex RF bearer frequencies to the PP. This provides a roboust and low latency wireless interface suitable for Human Interface Devices and audio devices, e.g. for gaming equipment.
