  • Patent number: 11909586
    Abstract: Techniques are described for providing logical networking functionality for managed computer networks, such as for virtual computer networks provided on behalf of users or other entities. In some situations, a user may configure or otherwise specify a network topology for a virtual computer network, such as a logical network topology that separates multiple computing nodes of the virtual computer network into multiple logical sub-networks and/or that specifies one or more logical networking devices for the virtual computer network. After a network topology is specified for a virtual computer network, logical networking functionality corresponding to the network topology may be provided in various manners, such as without physically implementing the network topology for the virtual computer network. In some situations, the computing nodes may include virtual machine nodes hosted on one or more physical computing machines or systems, such as by or on behalf of one or more users.

  • Patent number: 11750495
    Abstract: Systems and methods provide congruent bidirectional Segment Routing (SR) tunnels, namely congruent and fate-shared traffic forwarding for bidirectional SR tunnels. A bidirectional SR tunnel, as described herein, includes two unidirectional SR tunnels where the forward and reverse traffic directions follow the same path through the network when forwarded based on prefix and adjacency Segment Identifiers (SIDs). The term “congruent” is used herein to refer to the fact that the two unidirectional SR tunnels, i.e., the forward and reverse traffic directions, follow the same path through the network but in opposite directions. The guarantee of congruency is based on modification of the Segment Identifier (SID) configuration at the source nodes of each tunnel. Accordingly, the present disclosure maintains compatibility with existing Segment Routing configurations with the modifications solely at the source nodes.

The end to end delay considers latency through each layer the data packet transitions through after being conjured at an application layer of the transmitting device. The data packet is then transmitted from the transmitting device via the network path to the receiving device.

If a system detects data loss (e.g., packet loss) on a first port, a second port may be selected based on network reliability metrics for retransmission of the lost data. A port may for example, be selected for retransmission based on the following criteria: (1) the port has the longest consecutive duration without packet loss and (2) the port has received an acknowledgement for a packet that was sent more recently than the initial transmission of the lost packet.

  • Patent number: 11552705
    Abstract: In a wireless optical network with multiple coordinators or other access points, the coverage area of coordinators may overlap. Interference in the communication between coordinators and devices may occur in these overlapping coverage areas. Various embodiments propose an automatic allocation of reserved time slots to coordinators. These time slots support the coordinators to advertise their presence without interference and enable a device to detect the presence of a neighbour coordinator in a single MAC cycle. Cooperation of coordinators can be supervised by a global controller to determine non-interfering time schedules whereby the coordinators rely on interference reports from the devices in the overlapping coverage areas. Fast detection allows fast re-scheduling of time slots in the wireless optical network in order to prevent interference when a device that enters the overlapping coverage area of two coordinators.

    Abstract: Embodiments of this application provide a network optimization method, a network optimization system, and a network device, and relate to the communications field. A first network device adjusts, if it is detected that a communications link between the first network device and a second network device is in an abnormal state, a metric of at least one data flow received by the first network device; and the first network device selects a transmission path for the at least one data flow based on adjusted metric, and transmits the at least one data flow to the selected transmission path. In this way, load of the communications link is reduced, and the communications link is restored to a normal state.

  • Patent number: 11546184
    Abstract: Some examples relate to selection of a rendezvous point in an IP multicast network managing multicast group traffic. An example includes transmitting, from a controller in a cloud computing system, messages to a source device and a host device in an IP multicast-capable network, which may include two peer network devices that are virtualized to function as one virtual device. Based on the response to the messages, the controller may determine that the source device is present in OSI layer 3 and the host device is present in OSI layer 2. The controller may determine that the peer network are located downstream in relation to the determined layer of the source device. The controller may select a non-peer network device as a rendezvous point in the IP multicast-capable network. Further to the selection, the controller may synchronize an active-active configuration between the peer network devices.

  • Patent number: 11509583
    Abstract: Enhanced mesh network performance is provided by computation of a path metric with respect to multi-hop paths between nodes in a mesh network and determination of a path through the mesh network that is optimal according to the path metric. Information is communicated in the mesh network according to the determined path. Nodes in the mesh network are enabled to communicate via one or more wireless links and/or one or more wired links. The path metric optionally includes an effective bandwidth path metric having elements (listed from highest to lowest conceptual priority) including an inverse of a sustainable data rate, a number of wireless links, and a number of wireless and wired links. The sustainable data rate is a measure of communication bandwidth that is deliverable by a path for a period of time.

  • Patent number: 11496180
    Abstract: Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications.

  • Patent number: RE49275
    Abstract: Known intra-domain routing methods (e.g., OSPF and IS-IS) are link-state routing protocols with hop-by-hop forwarding that sacrifice optimal traffic engineering for ease of implementation and management. Known optimal traffic engineering procedures are either not link-state methods or require source routing—characteristics that make them difficult to implement. Certain embodiments of the present invention include a fully distributed, adaptive, link-state routing protocol with hop-by-hop forwarding configured to achieve optimal traffic engineering. Such embodiments facilitate significant performance improvements relative to known intra-domain routing methods and decrease network infrastructure requirements.
