  • Patent number: 11722366
    Abstract: A load control system may be commissioned using beacons. The load control system may include control devices that each include a beacon transmitting circuit configured to transmit a beacon that comprises an identifier associated with the control device. A network device, such as a mobile device, may discover a control device based on the beacon received from the control device. In response to discovery of the control device, the control device may be added to a temporary group of control devices for being collectively configured and/or controlled. Control devices may be discovered based on the signal strength at which the beacons are received. The control devices may provide feedback to a user in response to confirmation messages to indicate to a user that the lighting control device has been added to the temporary group. The control devices may stop providing the feedback after they are removed from the temporary group.

  • Patent number: 11722367
    Abstract: Some embodiments provide an elastic architecture for providing a service in a computing system. To perform a service on the data messages, the service architecture uses a service node (SN) group that includes one primary service node (PSN) and zero or more secondary service nodes (SSNs). The service can be performed on a data message by either the PSN or one of the SSN. However, in addition to performing the service, the PSN also performs a load balancing operation that assesses the load on each service node (i.e., on the PSN or each SSN), and based on this assessment, has the data messages distributed to the service node(s) in its SN group. Based on the assessed load, the PSN in some embodiments also has one or more SSNs added to or removed from its SN group. To add or remove an SSN to or from the service node group, the PSN in some embodiments directs a set of controllers to add (e.g., instantiate or allocate) or remove the SSN to or from the SN group.

  • Patent number: 11722401
    Abstract: This application discloses a method, an apparatus, and a system for processing a transmission path fault. In this application, after a first network device receives a packet, and when the first network device determines that a third network device is faulty, a difference between an initial value of a segment routing global block SRGB of the first network device and an initial value of an SRGB of the third network device is determined, and a backup path is determined based on the difference and a backup forwarding table. The first network device sends a first packet based on the backup forwarding table.

  • Patent number: 11722402
    Abstract: Provided is a Routing Early Warning System (“REWS”) that preemptively detects and corrects network issues based on control plane messaging. REWS receives control plane messages for network paths to a source node, groups the control plane messages to different bins based on time, detects an anomaly based on a number of a first set of control plane messages grouped to a particular bin differing, by a threshold amount, from a steady state number of control plane messages grouped to at least one other bin, and isolates a cause of the anomaly based on a number of updated paths and addressing of one or more nodes specified in the first set of control plane messages. REWS modifies routing of the source node data plane traffic before the anomaly significant impacts the data plane in response to detecting the anomaly and isolating the anomaly cause using the control plane messages.

  • Patent number: 11722403
    Abstract: A method may include receiving a domain name system (DNS) query at a network device, where the DNS query may be associated with a traffic flow identified for rerouting through an alternative path utilizing an alternative network device instead of a default path. The method may also include rewriting the DNS query such that the DNS query is routed through the alternative network device along the alternative path and to a DNS server associated with the alternative path. The method may additionally include receiving a DNS response from the DNS server, where a resource identified in the DNS response may be based on the DNS query coming through the alternative network device.

  • Patent number: 11722404
    Abstract: Techniques and mechanisms for compressing the size of SIDs to be smaller than a complete IPv6 address (or “micro SIDs”), and scaling micro SIDs across a multi-domain environment using micro SID-domain-blocks. Segment routing over IPv6 (SRv6) uses 128-bit IPv6 addresses as SIDs for segment routing. According to this disclosure, multiple SRv6 SIDs may be expressed in a compact format such that a 128-bit IPv6 address, such as the destination address field of the IPv6 header, may store multiple micro SIDs. Further, SID-domain-blocks may be assigned to each domain in a multi-domain network such that micro SIDs may be expressed in the context of a given domain, rather than being shared in the global multi-domain network. In this way, lists of domain-specific SIDs may be fully expressed in the IPv6 destination address of the packet to scale micro SID into large, multi-domain networks.

  • Patent number: 11722405
    Abstract: In exemplary embodiments of the present invention, a router determines whether or not to establish a stateful routing session based on the suitability of one or more candidate return path interfaces. This determination is typically made at the time a first packet for a new session arrives at the router on a given ingress interface. In some cases, the router may be configured to require that the ingress interface be used for the return path of the session, in which case the router may evaluate whether the ingress interface is suitable for the return path and may drop the session if the ingress interface is deemed by the router to be unsuitable for the return path. In other cases, the router may be configured to not require that the ingress interface be used for the return path, in which case the router may evaluate whether at least one interface is suitable for the return path and drop the session if no interface is deemed by the router to be suitable for the return path.

    Abstract: The disclosure provides an approach for deploying an software defined networking (SDN) solution for overlay routing of traffic on a host with colocated a workload virtual machine (VM), addressable on an overlay network and VM addressable on an underlay network. An overlay interceptor in a hypervisor of the host can intercept traffic from a virtual switch and route the traffic to destination VM. The overlay interceptor can route the traffic directly, without the traffic exiting the host. A fast path can be created for the routing.

  • Patent number: 11722414
    Abstract: Embodiments provide techniques for device-level traffic shaping in a communications network. Embodiments operate in communication networks providing connectivity to large numbers of user-side network nodes via shared communications links. For example, customer premises equipment (CPE) devices behind one of the user-side network nodes are classified into device types according to a predetermined rate-relevant characteristic of the CPE device. Upon receiving a forward-link (FL) traffic flow destined for one of the CPE devices, the device type of the CPE device is identified, and the FL traffic flow is shaped in accordance with a traffic shaping policy that corresponds to CPE device type. Various embodiments are tailored to support architectures having device-level shapers and/or network address translators (NAT) in user-side network nodes and/or in a provider-side network node.

  • Patent number: 11722416
    Abstract: This disclosure is directed to system to monitor and control data flow in a network. At least one device in a core network may be responsible for charging functions related to the data requests. During certain high usage scenarios (e.g., emergencies, special events, etc.), it may be possible for the charging system to be overwhelmed. For example, a policing system may be implemented in the core network to at least manage the flow of requests to the charging system. The policing system may monitor and control request flow to the charging system based on at least one policy. When a request is determined to violate a policy, the policing system may take corrective action to prevent the charging system from being overwhelmed. For example, the policing system may block the request, divert the request to another charging system that may have available capacity, etc.
