Techniques are disclosed for determining predictions from a graph of a network dataset. The graph of the network dataset may include nodes describing entities and edges describing connections or links between the entities. Predictions may be made using a dual-path convolution network that considers both node connectivity and node topology. Node topology includes assessment of similarities in topology roles between nodes in the graph, even nodes that reside in different parts of the graph. The node connectivity and node topology in the dual-path convolution may be aligned using a multi-head attention network. Outputs from previous layers of the multi-head attention network may be provided as inputs to subsequent layers of the dual-path convolution to mutually reinforce the convolutions determining node connectivity and node topology toward alignment.

A network system that uses a cluster of edge nodes to send and receive multicast traffic is provided. The network system is a network virtualization environment that includes one or more distributed routers, each distributed router implemented by virtualization software running on one or more host machines. The network system also includes a cluster of edge nodes for sending data from the one or more distributed routers to one or more uplink/upstream physical routers outside of a datacenter and for receiving data from the physical routers to the distributed routers. One of the edge nodes is a designated edge node that queries for membership information for one or more multicast groups to be received by at least two edge nodes of the cluster of edge nodes. The cluster of edge nodes forwards multicast traffic to and from the distributed routers according to the received membership information.

A method and an apparatus for routing data packets. The solution in a communication network including a set of nodes, storing information regarding nodes of the network; and when transmitting a data packet to a destination node in the network, determining and including in the data packet the recipient identification; determining and including in the data packet the direction of the destination node in the network; determining and including in the data packet a hop count indicator indicating the number of node-to-node hops to the destination node; setting in the data packet the transmission direction indicator equal to a value corresponding to direction down and transmitting the packet.

A network apparatus for a network software service layer (NSSL) service bus. The network apparatus includes a memory storing executable instructions and a processor coupled to the memory, the processor executing the executable instructions, where the processor is configured to receive a service description comprising a named service and a network identifier identifying a network node associated with the named service, select a service description according to the named service, and transmit a named service request to the network node according to the service description selected.

For logical multicasting in overlay networks, at a data processing system, an original unicast packet is received from a first component in a first computing node in an overlay network. To cause multicasting in the overlay network the received original unicast packet was unicast by the first computing node only to the data processing system, and a multicast data structure for the overlay network is maintained only by the data processing system, the multicast data structure containing information of each receiver that is configured to receive unicast packets during logical multicasting in the overlay network. From a set of subscriber receivers in the multicast data structure, a subset of the subscriber receivers is selected. A copy of the original unicast packet is unicast to each subscriber receiver in the subset.

An apparatus includes a low noise amplifier (LNA) multiplexer configured to receive a plurality of radio frequency (RF) signals at a plurality of input terminals and to combine the plurality of RF signals into a combined RF signal that is output at an output terminal. The LNA multiplexer includes a plurality of input signal paths, and each input signal path is coupleable to a respective input terminal of the plurality of input terminals and is configured to receive a respective RF signal of the plurality of RF signals. The apparatus further includes an LNA demultiplexer configured to receive the combined RF signal at an input port coupled to the output terminal and to distribute the combined RF signal to a plurality of output ports, each output port of the plurality of output ports configured to output the combined RF signal to a respective downconverter of a plurality of downconverters.

Methods, systems, and devices for wireless communications are described. A wireless device may establish connectivity between the wireless device and a user equipment (UE) via a first communication path, and between the wireless device and the UE via a second communication path that includes a relay device. The wireless device may transmit, via the first communication path, a first message in a first format to the UE, including first data, and transmit, via the second communication path to the relay device, a second message in a second format and including the first data, the second format indicating that the relay device is to relay the first data to the UE. The relay device may receive, via a first portion of the second communication path, the first message and may transmit, to the UE via a second portion of the second path, a second message including the first data.
