Abstract: Leveraging non-transient or persistent device identifiers to enforce device quarantine instead of IP addresses accommodates the transient associations of IP addresses to devices without compromising the effectiveness of quarantine. When a device has been determined to be compromised and is quarantined, the quarantine of the device is enforced using the IP address of the device. However, IP address assignment is transient. With each connection, a device can be assigned a different IP address. After a connection is established, a gateway can collect a device identifying value(s) that persists across network connections (e.g., host identifier (host ID) and device serial number). With a persistent device identifier, a quarantine list can be enforced in a data/forwarding plane regardless of a compromised device being assigned different network addresses.

Abstract: This disclosure describes methods of operating a leaf node device, such as a switch device, connected to a switch fabric of a network. The leaf node device receives, from another leaf node device via the switch fabric, an indication of a secure route to a host device. In response to receiving the indication of the secure route, the leaf node device creates or updates a routing entry for the host device in a routing information base of the leaf node device and creates or updates an entry for the host device in a Dynamic Host Configuration Protocol (DHCP) snoop database of the leaf node device. The leaf node may thereby communicate with the host device that is attached to the leaf node device as a result of moving from the other leaf node device.

Abstract: Data transfer for access points or switches in a cluster upon data tunnel failure is described. An example includes receiving uniform mapping information for a cluster including a bucket map mapping an active gateway and a standby gateway for each of multiple entries, the bucket map including mapping a first gateway node as a standby gateway and a second gateway node as an active gateway for an entry. Synchronized user information is received from the second gateway node including identification of a user indexed to the first entry. A message is received from a first AP or switch requesting activation of the user on the first gateway node as a standby gateway upon failure of a data tunnel between the first AP or switch and the second gateway node. The user is activated on the first gateway node.

Abstract: Embodiments of the present invention are drawn to electronic systems capable of transmitting a group addressed frame that identifies an MLD according to an MLD MAC address. The group addressed frame can include an ARP request, for example, and can be transmitted by an AP MLD responsive to an individually addressed frame transmitted by a non-AP STA MLD associated with the AP MLD. The AP MLD can provide a proxy ARP service for associated non-AP STA MLDs.

Abstract: The present invention relates to a system and method for managing push notifications on a user device. The push notifications may be sent only upon checking/identifying if the user device (associated smart extension) is within a predetermined vicinity of a home gateway network by checking whether respective MAC address entry of the user device is in ARP tables and is in active state, based on which push notifications may be triggered to the user device, wherein the MAC address may be computed and stored by the system. Alternatively, the system may determine if the user device is reachable or not by using IP address (such as ping protocol and other such methods). This facilitates a consistent, power saving along with better reliability of network-based calls or Push notifications, an enhanced user experience and other advantages by sending the push notifications only when the device is connected to home gateway network.

Abstract: A Layer 2 (L2) domain hierarchical address communication system includes a first computing device that provides a first host, and a second computing device that provides a second host. A first leaf switch device is connected to the first computing device, and a second leaf switch device that is connected to the second computing device and coupled to the first leaf switch device. The first leaf switch device receives a first data communication from the first host that includes a second hierarchical MAC address of the second host. The first leaf switch device identifies a hierarchical MAC prefix in the second hierarchical MAC address, and uses the hierarchical MAC prefix to forward the first data communication to the second leaf switch device.

Abstract: Techniques are described for managing communications between multiple computing nodes, such as for computing nodes that are part of managed virtual computer networks provided on behalf of users or other entities. In some situations, one or more of the computing nodes of a managed virtual computer network is configured to perform actions to extend capabilities of the managed virtual computer network to other computing nodes that are not part of the managed virtual computer network, such as by forwarding communications between computing nodes of the managed virtual computer network and the other external computing nodes so as to enable the other external computing nodes to participate in the managed 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.

Abstract: Systems, methods, and apparatus to identify media devices are disclosed. An example network communications monitor includes network interface circuitry, computer readable instructions, and processor circuitry. The processor circuitry is to execute the computer readable instructions to detect, via the network interface circuitry, multiple network communications transmitted on a home network within the household, access panelist data that associates a panelist of the household with a panelist device of the panelist, determine, based on the panelist data, that one or more of the multiple network communications are associated with the panelist device, and cause storage of data identifying the one or more network communications in association with the panelist.

Abstract: An embodiment includes a method of self-election of a node in a subnet. The method includes receiving a first ping message. The first ping message is unicast from a second node, includes direct information related to the second node, and includes indirect information related to a third node. The method includes updating a first status of the second node in a status list stored at the first node consistent with the direct information. The method includes determining whether statuses of a threshold number of nodes have been received. Responsive to the threshold number of nodes being received, the method includes performing a local election operation. The method includes propagating a second ping message to a randomly identified additional node. The second ping message includes direct information regarding the first node and indirect information regarding at least one other node.

Abstract: One embodiment of the present invention facilitates address resolution protocol (ARP) resolution in an extended subnet. A gateway of a first segment of the extended subnet can determine that a layer-2 address corresponding to a layer-3 destination address of a packet is locally unavailable. The gateway can then determine whether a respective egress interface of an ARP request for the layer-3 destination address is associated with a layer-2 subnet extension from the first segment to a second segment of the extended subnet. The extension can provide a common layer-2 broadcast domain comprising the first and second segments with a same default gateway layer-3 address. If the egress interface is associated with the extension, the gateway can insert a layer-3 address of a first endpoint associated with the extension as a source protocol address in the ARP request. The gateway can send the modified ARP request via the egress interface.
