  • Patent number: 11924119
    Abstract: Techniques and architecture are described that utilize switchport protected flags to provide switchport protected functionality across network devices, e.g., switches, routers, etc., in fabric networks. For example, a first port of a first network device of a fabric network receives a packet from a first host destined for a second host. The second host is onboarded to the fabric network via a second port of a second network device. It is determined (i) if a first protected flag associated with the first port of the first network device is set as true and (ii) if a second protected flag associated with the second host is set as true. Based at least in part on (i) the first protected flag associated with the first port being set as true and (ii) the second protected flag being set as true, the first network device drops the packet.

The second set of metadata is stored using a second storage mechanism that comprises a distributed metadata storage facility that stores metadata across multiple storage locations having at least one of the multiple storage locations that is not local to the node that stores data and metadata using the first storage mechanism.

  • Patent number: 11736384
    Abstract: According to an embodiment, a node of a communication system includes a memory and one or more processors coupled to the memory. The one or more processors are configured to: determine, when receiving a packet including path information that indicates a parent-child relationship of transfer nodes included on a network topology from a source node to a destination node, whether at least one of its own node and a neighboring node is included in the path information as the transfer node; specify a distance between the own node and the destination node when at least one of the own node and the neighboring node is included in the path information; and transmit a confirmation response for the packet to the wireless multi-hop network after a waiting time corresponding to the distance, and transfer the packet when a confirmation response is not received from the neighboring node during the waiting time.

  • Patent number: 11729152
    Abstract: Embodiments are directed to managing communication over one or more networks. An underlay network that couples a source gateway and a target gateway using underlay protocols may be provided such that the target gateway includes two or more port groups that may each be associated with a separate target node. An overlay network may be provided on the underlay network based on policy information such that the source gateway and the target gateway may each be assigned separate gateway identifiers (GIDs) that are associated with the overlay network. In response to the source gateway authorizing a source node to employ the overlay network to communicate one or more encrypted payloads to a target node, the one or more encrypted payloads may be provided to the target node based on the overlay network and the policy information.

  • Patent number: 11722375
    Abstract: Systems and methods for reducing bandwidth loss in IPv6 packet switching networks. A network appliance is configured to sample IPv6 packets and mirror sampled packets to a working memory or memory structure, such as a queue. A transport layer payload is extracted from each sampled packet and a transport layer checksum validation operation is performed. Upon detecting an error, the network appliance updates a dropped packet rate or other metric.

  • Patent number: 11722465
    Abstract: Methods, systems, computer-readable media, and apparatuses may provide password encryption for hybrid cloud services. A workspace cloud connector internally residing with an entity may intercept user credentials associated with an internal application being transmitted to an external cloud service. The workspace cloud connector may generate an encryption key and encrypt the user credentials via a reversible encryption methodology. The workspace cloud connector may encrypt the encryption key using an irreversible encryption methodology (e.g., use a hashing function to produce a first hash). The workspace cloud connector may transmit the encrypted user credentials and the first hash to a virtual delivery agent via a first path (e.g., via the external cloud service). In response, the workspace cloud connector may receive an address of the virtual delivery agent and, using the address, may send the encryption key to the virtual delivery agent via a second path different from the first path.

  • Patent number: 11695693
    Abstract: A packet transmission method, device, and system for network technologies are disclosed. A first network device receives, by using a first VPLS instance a packet to be sent to a user-side device connected to the second network device. The first network device forwards, based on an association relationship between the first VPLS instance and the first VPWS instance, the packet to a second VPWS instance in the second network device by using the first VPWS instance. A VPLS instance is associated with a VPWS instance in the first network device. A packet that is received by using the VPLS instance and that is to be sent to a user-side device can be forwarded by using the associated VPWS instance, so that pressure to learn a MAC address for packet transmission is reduced, and forwarding performance of the system is ensured.
