    Abstract: At least one embodiment takes the form of a process carried out by a given mobile radio in a group of mobile radios. The process includes broadcasting heartbeat messages in accordance with a group-wide symmetric-timing protocol and maintaining an in-range list of mobile radios. The in-range list is maintained at least in part by (i) adding mobile radios that are not already on the in-range list to the in-range list upon detecting transmissions from such mobile radios; (ii) maintaining, for each mobile radio on the in-range list, a respective keepalive timer in accordance with the group-wide symmetric-timing protocol; and (iii) removing mobile radios from the in-range list upon expiration of the respective keepalive timers. The process further includes presenting an alert via a user interface when a count of mobile radios on the in-range list falls below a notification threshold.

    Abstract: A method and wireless device (700) for applying a Radio Resource Control, RRC, configuration in a radio communication between the wireless device and a serving base station (702a) of a wireless communication network (702). The wireless device (700) obtains a set of RRC configurations (704), each RRC configuration comprising a plurality of radio parameters dictating how the wireless device should operate in the network (702). The wireless device (700) further receives an indication (706) from the serving base station reflecting a network state of the wireless communication network (702), and then selects and applies an RRC configuration out of the set of RRC configurations, based on the received indication. Thereby, capacity and performance can be improved in the network by reduced signalling with the wireless device (700) and more flexible usage of RRC configuration suitable for the network state.

  • Patent number: 9860309
    Abstract: Network traffic in a cloud computing system is monitored in response to a request to capture network traffic of a tenant port of a first virtual machine (VM) executing in the cloud computing system, wherein the first VM is associated with a first tenant organization different from a second organization managing the cloud computing system. A decapsulating VM having a first network interface and a second network interface is instantiated, wherein the decapsulating VM is inaccessible to the first tenant organization. An encapsulated port mirroring session from the tenant port of the first VM to the first network interface of the decapsulating VM is then established. A plurality of packets comprising captured network traffic received via the encapsulated port mirroring session are decapsulated, and the captured network traffic is forwarded via the second network interface of the decapsulating VM to a sniffer VM.

  • Patent number: 9853822
    Abstract: Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a packet at a node. The packet includes a multicast forwarding entry. The multicast forwarding entry has a plurality of elements, and each element corresponds to a particular node. The method also involves comparing the multicast forwarding entry with forwarding information stored by the node. The method involves selecting a neighbor node based on the comparing, updating the multicast forwarding entry in the packet, and forwarding the packet to the neighbor node.

  • Patent number: 9853933
    Abstract: The method including receiving, at a first node of a plurality of computing nodes, a message ownership migration request for a first message. The message ownership migration request can originate from a second node of the plurality of computing nodes. The first node can be an owner of the first message in a first instance of a message queue at the first node. The first message can be published from a first publisher to the message queue at one of the nodes of the plurality of computing nodes. The first message in the first instance of the message queue at the first node can be replicated at a second instance of the message queue at the second node. A first subscriber can be subscribed to the second instance of the message queue at the second node. The method also can include designating the second node as a new owner of the first message such that the first node is no longer the owner of the first message.

  • Patent number: 9847949
    Abstract: Examples disclosed herein relate to receiving, by a scheduler, a request for a window during which to send a data packet through a crossbar. Transmission of the data packet is dependent upon a pool of transmission credits. The scheduler determines whether the pool of transmission credits is sufficient for transmitting the data packet, and when it is determined that the pool of transmission credits is insufficient, the scheduler determines whether to block the request or to speculatively arbitrate the window based on a value of a speculative request counter.

  • Patent number: 9843502
    Abstract: A multi-domain network (5) has a Hierarchical Path Computation Element, H-PCE, architecture comprising a Parent Path Computation Element, P-PCE (31) and a Child Path Computation Element, C-PCE, (21-25) at each of the domains (11-15). A C-PCE (21-25) determines summarised domain topology information about the domain (11-15). The summarized domain topology information comprises at least one of: an indication of whether the domain (11-15) is capable of supporting Point-to-Multi-Point services; an indication of whether a node of the summarised domain topology is capable of supporting a branch point for Point-to-Multi-Point services. The summarised domain topology information is sent to a P-PCE (31) via a communication interface (35). The P-PCE (31) computes an end-to-end Point-to-Multi-Point tree using a topology based on summarised domain topology information (32) received from the Child Path Computation Elements.

  • Patent number: 9838309
    Abstract: In general, techniques for facilitating a distributed network (L3) subnet by which multiple independent control planes of network devices connected to physically separate L2 networks provide L2 reachability to/from a single L3 subnet. In some examples, a shared L2 network physically situated to connect a plurality of physically separate L2 networks “stitches” the L2 networks together within the respective, independent control planes of switches such that the control planes bridge L2 traffic for a single bridge domain for the separate L2 networks to the shared L2 network and visa-versa. Each of the independent control planes may be configured with a virtual IRB instance associated with the bridge domain and with a common network subnet. Each of the virtual IRBs provides a functionally similar routing interface for the single bridge domain for the separate L2 networks and allows the shared network subnet to be distributed among the independent control planes.

  • Patent number: 9838327
    Abstract: In general, techniques are described in which packet replicators of a network device cooperate to generate a distributed hierarchical forwarding structure that the packet replicators then use to replicate and forward multicast packets to multiple output interfaces. For example, packet forwarding engines (PFEs) of a router each receive a new list of interfaces for a multicast packet stream. The PFEs individually construct a hierarchical forwarding structure based on the interface list. The hierarchical forwarding structure specifies interrelationships among the PFEs, which occupy nodes within the hierarchy. Each child PFE determines from the hierarchical forwarding structure the identity of a parent PFE and issues a token, constituting forwarding state for the distributed hierarchical forwarding structure, to the parent PFE.
