Abstract: A deterministic flow forwarding method and apparatus, a storage medium and an electronic device are provided. The method includes: sending, by a controller, a Segment Routing (SR) policy carrying deterministic path information to an edge node of a network, wherein the SR Policy is used for instructing the edge node of the network to forward a deterministic flow according to the deterministic path information. By virtue of the above technical solution, the problem that a controller cannot implement distribution of a deterministic path by an SR Policy is solved.

Abstract: An avionics data communication network includes a computing device configured to asynchronously transmit data packets in parallel via three or more redundant network interface controllers (NICs). The data packets offered to the avionics data communication network are bound using a token bucket filter (TBF). Three or more redundant network switches are configured to receive and relay the data packets from a different NIC of the three or more redundant NICs of the computing device. An avionics device is configured to receive the data packets from the computing device within a deterministic end-to-end transmission delay bound, the avionics device receiving the data packets via at least one of the three or more redundant network switches.

Abstract: A method is disclosed for distributed routing data with latencies using relay nodes. The method includes automatically measuring one-way latencies between a plurality of nodes comprising a first node, a second node, and a relay node, producing a first signal associated with a proof of uptime for the relay node, producing a second signal associated with a proof of bandwidth for the relay node, after the proof of uptime and the proof of bandwidth of the relay node are validated, automatically identifying a relayed data routing path from the first node to the second node via the relay node based on the one-way latencies between the plurality of nodes, in response to a command to transfer data from the first node to the second node, and transferring data from the first node to the second node along the relayed data routing path.

Abstract: The present application relates to egressing traffic from a public cloud network. An egress traffic manager configures routing at hosts and edge routers within the public cloud network. The egress traffic manager determines, for an edge router, a plurality of current border gateway protocol (BGP) sessions with external networks. The egress traffic manager configures a virtual router hosted on the edge router to route a portion of egress traffic to a selected one of the external networks via one of the BGP sessions. A host is configured to route the portion of egress traffic within the public cloud network to the edge router. An edge router configured to route, by the virtual router, the portion of egress traffic from the edge router to the selected one of the external networks.

Abstract: Some embodiments provide a method of implementing context-aware routing for a software-defined wide-area network, at an SD-WAN edge forwarding element (FE) located at a branch network connected to the SD-WAN. The method receives, from an SD-WAN controller, geolocation route weights for each of multiple cloud datacenters across which a set of application resources is distributed. The application resources are all reachable at a same virtual network address. For each of the cloud datacenters, the method installs a route for the virtual network address between the branch network and the cloud datacenter. The routes have different total costs based at least in part on the geolocation metrics received from the SD-WAN controller. The SD-WAN edge FE selects between the routes to establish connections to the set of application resources.

Abstract: An information processing device that performs communication via a network includes: a storage unit that stores a receiving unit that receives data acquired by a device; the data; and past data received by the receiving unit before the data; a calculating unit that calculates a delay time in the network; a determination unit that determines, based on the calculated delay time, one or more past data used for prediction of future data that is not received by the receiving unit from the past data stored in the storage unit; and a predicting unit that predicts the future data using the determined past data.

Abstract: A method of managing inter-branch communication is a network, including generating an end-to-end path, wherein the end-to-end path starts in a first computing device in a first branch and ends at a second computing device in a second branch, wherein the end-to-end path is generated using a plurality of flow records and a plurality of path records and the end-to-end path includes a wide area network (WAN) segment, and issuing, based on the generating, a notification to a network administrator, wherein the notification specifies the end-to-end path and a latency associated with at least one segment in the end-to-end path.

Abstract: Systems and methods for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, an asynchronous system includes a first wireless node having a wireless device with one or more processing units and RF circuitry for transmitting and receiving communications in the wireless network architecture including a first RF signal having a first packet. The system also includes a second wireless node having a wireless device with a transmitter and a receiver to enable bi-directional communications with the first wireless node in the wireless network architecture including a second RF signal with a second packet. The first wireless node determines a time of flight estimate for localization based on a time estimate of round trip time of the first and second packets and a time estimate that is based on channel sense information of the first and second wireless nodes.

Abstract: Embodiments disclosed include a method and apparatus for global traffic control and optimization for software-defined networks. In an embodiment, data traffic is optimized by distributing predefined metrics (data traffic information) to all controllers in the network. The predefined metrics are specific to local network switches and controllers, but are distributed to all peers at configurable intervals. “Local” as used herein implies one POP and its associated switch and controller. The method of distribution of local POP metrics is strictly in band using a packet as defined by the protocol used by the data network.

Abstract: A first machine identifies, from among a non-static collection of machines, a respective set of forward contacts that comprises a set of machines. The set of forward contacts are distributed along the ordered sequence in the forward direction away from the respective machine in an order of increasing similarity between the respective channel number assigned to the first machine and a respective channel number assigned to each of the set of forward contacts. The first machine establishes a respective direct communication channel between the first machine and each of the set of forward contacts. The first machine sends a first query to a first forward contact and sends collected answers for the first query to at least a second forward contact that has a greater similarity to the first machine based on the respective channel numbers of the first machine and the first and second forward contacts.
