Abstract: A software-defined networking (“SDN”) capable forwarding switch includes ports for receiving and/or outputting data packets and a packet pipeline including a forwarding table. The forwarding table is configured to contain a number of flow table entries (“FTEs”), that determine the forwarding switch's configuration and control behavior. The switch further includes a control engine configured to manipulate the forwarding switch's forwarding tables by adding, updating, and/or removing FTEs in the forwarding tables. An FTE of a forwarding table is configured to contain a specific action part that includes an action instruction to create a control packet and to send it to the control engine. The control packet includes embedded control instructions that cause the control engine to change the forwarding switch's configuration and/or control behavior.

Abstract: A method for synchronizing data parallel deep learning nodes includes: training, by a deep learning node of the data parallel deep learning nodes, a deep learning model, having a hierarchy of layers, using backpropagation; interleaving, by the deep learning node, layer-wise backpropagation calculations with backpropagation message communications; assigning, by the deep learning node, priority levels to the backpropagation message communications based on the hierarchy of layers; and prioritizing, by the deep learning node, transmission among the backpropagation message communications based on the priority levels. At least one of the backpropagation message communications transmits a message having information on at least one of a gradient or a weight.

Abstract: A method for operating a home gateway that implements hybrid access with a number of interfaces to different access networks includes resolving, by a domain name service (DNS) proxy function of the home gateway, DNS resolution requests received from a client of the home gateway; and returning, by the DNS proxy function, corresponding DNS resolution responses to the client. The DNS proxy function, based on a single DNS resolution request from the client, requests a number of DNS resolutions via different interfaces of the home gateway transparently to the client.

Abstract: A method of managing a multipath TCP (MPTCP) connection includes establishing the MPTCP connection as a logical connection between end-points that utilizes multiple network paths with one TCP subflow per network path. At least two subflows of the MPTCP connection are terminated at different end-points.

Abstract: A method for performing load balancing among a plurality of multipath-capable servers being provided behind a load balancer and being configured to process requests from multipath-capable clients includes contacting, by a first multipath-capable client, the load balancer for establishing an initial subflow. The method further includes selecting, by the load balancer from the plurality of multipath-capable servers, a selected server by applying a load balancing algorithm, and forwarding, by the load balancer, packets of the initial subflow to the selected server and not accepting any further subflows from the client. The method further includes announcing, by the selected server, at least one public interface to the client via the initial subflow for establishing any subsequent subflows directly between the client and the selected server.
