  • Patent number: 10938732
    Abstract: Various systems and methods take advantage of physical interfaces that are a part of Link Aggregation Group (LAG) to avoid traffic drops when disruptive configurations are applied to a port of a switch or router. In embodiments, in networking topologies using (SAN)-based traffic, where zero losses are expected, lossless deployment may be accomplished by using LACP to proactively intervene and redirect traffic flow in both ingress and egress directions of a to-be-configured port, e.g., to other ports of the LAG.

  • Patent number: 10911296
    Abstract: Techniques are described for providing targeted selection of cascade ports of an aggregation device. In one example, the disclosed techniques enable dynamic assignment of active and backup cascade ports of an aggregation device for each extended port of satellite devices. In this example, rather than allocating resources for each of the extended ports of the satellite devices on all of the cascade ports of the aggregation device, the aggregation device instead allocates resources for each of the extended port only on the assigned active and backup cascade ports for the respective one of the extended ports of the satellite devices. The techniques are also described for providing traffic steering to a backup cascade port in the event the assigned active cascade port is unreachable, and, if the cascade port remains unreachable for a specified duration, the aggregation device may assign new active and backup cascade ports for the extended port.

  • Patent number: 10912004
    Abstract: In a cellular telecommunications system, outage management is managed in respect of each cell B by a nominated neighbor cell A, the identity of which is recorded in a neighbor list for cell B. If a cell C, D, other than the nominated neighbor, detects a suspected outage in a cell B, the cell detecting the outage identifies the nominated neighbor A from the neighbor list of cell B, and transmits an outage report to the nominated neighbor cell A, which coordinates a handover and outage management process. This avoids multiple detections of the same outage resulting in conflicting attempts to manage the recovery process.

  • Patent number: 10819563
    Abstract: Systems, methods, and non-transitory computer-readable storage media for recovering from a partial failure of a virtual port chain (vPC) domain. The first and second vPC peers may be paired to create a vPC having a virtual address. An endpoint host may communicate with a network via the virtual port channel. The system may detect that the first virtual port channel peer is down. During or after the first vPC reboots, the reachability cost for the first vPC with regards to the virtual address can be set to an inflated value. The first vPC peer may also delay its bring up time while it synchronizes its vPC state information with the second vPC peer. The second vPC can continue to advertise the association between the endpoint host and the virtual address. Upon completion of the synchronization, the first vPC peer may bring up the link and restore the reachability cost.

    Abstract: A method is provided that facilitates sidehaul minimization by dropping and reconnecting a mobile device when the mobile device has handed off to a second deployable in a deployable ad hoc communication system. A data session is established for the mobile device utilizing resources in the first deployable. At some point the mobile device hands over to a second deployable in the multiple deployable ad hoc network. The data session at the first deployable remains active and continues to send and receive bearer traffic and control traffic for the mobile device. Upon determining that the mobile device has entered an idle state, the mobile device is dropped from the second deployable and reconnects back to the second deployable. By dropping and reconnecting, the data and bearer sessions are moved from the first deployable to the second deployable, thereby eliminating sidehaul between the first deployable and the second deployable.

The action flow table of the security group includes a packet action for a packet that successfully matches the security group. The method provided in this application lowers complexity of a flow table used to implement security group matching, and improves security group matching efficiency.

  • Patent number: 10708812
    Abstract: The invention relates to a method for discovery of one or more relay user equipments within a mobile communication network. A relay user equipment is capable to perform direct communication over a direct sidelink connection respectively with one or more remote user equipments, and is further capable to serve as a relay respectively for the one or more remote user equipments to relay communication between the one or more remote user equipments and the radio base station. The relay user equipment determines whether an overload situation exists in the relay user equipment or not, the overload situation preventing the relay user equipment to serve as a relay for a further remote user equipment. The relay user equipment transmits a relay discovery message, at least comprising an overload indication providing information on the result of the determination as to whether the overload situation exists in the relay user equipment.

  • Patent number: 10693679
    Abstract: Techniques are disclosed for an Ethernet Virtual Private Network (EVPN) Virtual Private Wire Service (VPWS) network with service interface-aware forwarding. In one example, a first network device signals to a second network device, using EVPN route advertisements, a multi-service service tunnel to transport network packets for a plurality of services. The services are identifiable by virtual local area network (VLAN) identifiers in the packets. The first network device is configured with a single transport interface for the service tunnel and the single transport interface is configured with respective service interfaces for the services. The first network device detects failure of a failed service interface of the service interfaces and outputs, in response to the failure, an EVPN route withdrawal message for the service tunnel that identifies the service corresponding to the failed service interface.

    Abstract: Techniques described and suggested herein include systems and methods for optimizing network connections by using attributes of one or more of the connected entities. For example, a routing engine may be implemented to determine, based on various attributes of a client device, its desired destination, and/or the networks capable of connecting the client device and the destination, optimized parameters and routes for the network connection. Such optimization may involve the selection of an optimal network, the negotiation of an optimal connection type, and the like. The optimization may be made for one or more disparate criteria, such as data security, bandwidth, network latency, geographical proximity, and so forth.

  • Patent number: 10666550
    Abstract: A method for determining a termination point of at least one tunnel or segment in a packet switching network. The network includes a set of routers and links between them, the routers and links forming a previous network topology, a transit router receiving packets intended for an output router, an event modifying the previous topology into a subsequent network topology, and a backup path between the transit router and the output router being calculated for the subsequent topology. The method includes calculating, prior to the event, for each router, an initial tree based on the previous topology, which has as a root the router and has as branches paths of minimum cost between the root and the other routers. A termination point of a tunnel or segment is obtained to prevent packets transiting between the start router and the output router from entering into a micro-loop caused by the event.

  • Patent number: 10606784
    Abstract: Sideband device management bus messages are filtered using software operations in order to minimize dropped messages and to maintain the bus in an operable state. Redundant sideband device management buses are utilized in order to provide fail-over transmission of messages in scenarios where one of the buses becomes inoperable. Multi-packet messages are transmitted to managed devices via the sideband bus connections. If an inoperable state is detected in a sideband bus connection during transmission of a multi-packet message, the portion of the multi-packet message not received by the managed device is transmitted via a redundant sideband bus connection with the managed device. Software filtering of bus transactions utilizes a circular DMA buffer for storing all incoming transactions. Transactions of interest are copied to buffers associated with specific endpoints for processing.
