A centralized control point determines a correspondence between at least two multicast groups and at least two RPs in a rendezvous point set according to information about the at least two multicast groups and information about the at least two RPs, where in the correspondence between the at least two multicast groups and the at least two RPs, each RP is corresponding to a same quantity of multicast groups; the centralized control point evenly allocates the at least two multicast groups to the at least two RPs according to the correspondence between the at least two multicast groups and the at least two RPs and diffuses the correspondence between the at least two multicast groups and the at least two RPs to all multicast routers on a PIM network.

A transceiver is designed to share memory and processing power amongst a plurality of transmitter and/or receiver latency paths, in a communications transceiver that carries or supports multiple applications. For example, the transmitter and/or receiver latency paths of the transceiver can share an interleaver/deinterleaver memory. This allocation can be done based on the data rate, latency, BER, impulse noise protection requirements of the application, data or information being transported over each latency path, or in general any parameter associated with the communications system.

A control device (15a) includes a control unit configured to: acquire a switching request based on a latency measured in a first application function (AF) (30) disposed in a first network slice (5) or in a terminal device (40) communicating with the first AF (30); and switch, based on the acquired switching request, a core network to be connected to the terminal device (40) from a first core network (10a) disposed in the first network slice (5) to a second core network (10b) disposed in a second network slice (6) by using the first AF (30), or using the first AF (30) and the terminal device (40), as an anchor.

A distributed deep learning system includes a plurality of calculation nodes connected to one another via a communication network. Each of the plurality of calculation nodes includes a computation unit that calculates a matrix product included in computation processing of a neural network and outputs a partial computation result, a storage unit that stores the partial computation result, and a network processing unit including a transmission unit that transmits the partial computation result to another calculation node, a reception unit that receives a partial computation result from another calculation node, an addition unit that obtains a total computation result, which is a sum of the partial computation result stored in the storage unit and the partial computation result from another calculation node, a transmission unit that transmits the total computation result to another calculation node, and a reception unit that receives a total computation result from another calculation node.

A method includes establishing communication between a first user device and a second user device using a first codec and filtering an input signal indicating an estimated unfiltered available bandwidth for the communications by applying a current filter including one of a first filter when the estimated unfiltered available bandwidth is less than a first threshold value or greater than a second threshold value or a second filter when the estimated unfiltered available bandwidth is between and including the first and second threshold values. The method includes adaptively switching the current filter as a function of the filtered input signal and the first and second threshold values. When the filtered input signal satisfies a channel bandwidth threshold for at least a predetermined period of time, the method includes switching from using the first codec to using a second codec for the communication between the first and second user devices.
