  • Patent number: 11652736
    Abstract: Systems and methods are provided to enable packets of network traffic to be hashed to available network gateway. Each packet can include a route table with a pool of network gateways as a next-hop of the packet. A network device may intercept the packet and hash the packet to a network gateway of the pool of network gateways. The network gateway can correspond to a stateful network router and the stateful network router can transmit the packet to a network appliance. The network device can monitor and perform health-checks on the network gateways, the stateful network routers, and the network appliances. The network device can remove components that are no longer healthy or available and can add components that subsequently become healthy.

  • Patent number: 11638185
    Abstract: A cell handover method and a device are provided, so that a target eNB uses a current serving small node as a user plane serving node after a UE is handed over. The UE and uses the target eNB as a control plane serving node after the handover. The method includes receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. According to the application, a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great is avoided, because the current serving small node forwards a large amount of data to the target eNB.

  • Patent number: 11632261
    Abstract: Some examples relate to managing multicast group traffic. In an example, a switch anchor controller receives a request for a multicast group from an associated network switch in a multicast-capable network. The associated network switch registers to the switch anchor controller in the multicast-capable network. In response to the request, the switch anchor controller selects a non-anchor controller in the multicast-capable network to serve the multicast group to the associated network switch. The switch anchor controller provides the information related to the non-anchor controller to the associated network switch, which in response creates a specific multicast tunnel between the associated network switch and the non-anchor controller to transfer multicast traffic related to the multicast group.

  • Patent number: 11627603
    Abstract: A first node in a TSCH network may receive a message-initiation packet from a second node on the TSCH network. Based on information in the message-initiation packet, the first node may determine a transmission time for a message content packet that is associated with the message-initiation packet. The first node may generate or modify a node-specific transmission delay that indicates a backoff associated with the second node. The node-specific transmission delay may indicate a quantity of backoff time slots during which the first node delays initiating a transmission with the second node. If the first node receives, during the node-specific transmission delay, an additional packet intended for the second node, the first node may queue the additional packet until after the node-specific transmission delay is completed.

  • Patent number: 11627525
    Abstract: A network system comprises a first logic block providing a link to a first network via an access point of a WLAN and a second logic block communicating with a node of a second network (such as a WPAN) and configured to provide a link between the node and the first network via the access point. The network system is configured to maintain continuous connections to both the access point and the node while receiving power. The second logic block can communicate with the node using a modified communication protocol that is only partially compliant with an 802.11x communications protocol. A wireless hub can integrate a WPAN with a WLAN including, in part, a wireless circuit compliant with the WLAN standard (such as an 802.11x standard), a processor, and a memory. The wireless circuit can connect to the WPAN without losing connectivity (such as association and synchronization) to the WLAN.

  • Patent number: 11621914
    Abstract: Techniques are disclosed for maintaining processing unit core affinity for fragmented packets. In one example, a service physical interface card (PIC) implementing a service plane of a network device receives fragmented and/or non-fragmented packet data for a traffic flow. The service PIC comprises at least one processing unit comprising multiple cores. A routing engine operating in a control plane of the network device defines one or more core groups comprising a subset of the cores. The routing engine assigns the traffic flow to a core group and a forwarding engine operating in a forwarding plane of the network device forwards the packet data for the traffic flow to the assigned core group. A core of the assigned core group applies a network service to the fragmented and/or non-fragmented packet data for the traffic flow, and the forwarding engine forwards the packet data for the traffic flow toward a destination.

  • Patent number: 11622406
    Abstract: The present disclosure relates to dual connectivity methods. In one example method, a first access network device sends a request message to a second access network device, where the request message is used to request the second access network device to serve as a secondary access network device of a terminal served by the first access network device. Then, the first access network device receives an acknowledgment message from the second access network device, where the acknowledgment message is used to acknowledge to the first access network device that the second access network device agrees to serve as the secondary access network device of the terminal.

  • Patent number: 11616685
    Abstract: A data link error feedback signaling system includes a transmitting network device and a receiving network device. The receiving network device may be operable to receive a network data unit from the transmitting network device over a data link, detect an error in the network data unit, and provide data link integrity information based on the error to the transmitting network device. The receiving network device may provide the data link integrity information by marking the data link flawed in a routing protocol, transmitting the data link integrity information via an informational protocol, and so on. The transmitting network device may respond to the data link integrity information, such as by marking the data link less preferred, marking the data link down, transmitting an alarm regarding the data link to a network operator, omitting taking an action upon determining that errors are below an error threshold, and so on.

  • Patent number: 11606294
    Abstract: Some embodiments of the invention provide novel methods for facilitating a distributed SNAT (dSNAT) middlebox service operation for a first network at a host computer in the first network on which the dSNAT middlebox service operation is performed and a gateway device between the first network and a second network. The novel methods enable dSNAT that provides stateful SNAT at multiple host computers, thus avoiding the bottleneck problem associated with providing stateful SNAT at gateways and also significantly reduces the need to redirect packets received at the wrong host by using a capacity of off-the-shelf gateway devices to perform IPv6 encapsulation for IPv4 packets and assigning locally unique IPv6 addresses to each host executing a dSNAT middlebox service instance that are used by the gateway device.
