  • Patent number: 9860935
    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: 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.

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: 9767114
    Abstract: A content-dissemination system distributes, publishes, or makes available a content item to one or more target entities based on contextual information associated with the content item. When a user creates a new content item or the system detects a new content item for a local user, the system determines contextual information for the content item, and uses this contextual and previous historical contextual information to generate a set of structured names for the content item. The system also determines security and privacy polices for disseminating the content item from the determined contextual information and the historical contextual information. The system associates the set of structured names and the security and privacy policies with the content item, and can disseminate the content item to one or more target entities based on these structured names, the security and privacy policies, and the requirements and capabilities of the recipients.

  • Patent number: 9756497
    Abstract: Session continuity may be maintained when communication devices transition from communicating through network infrastructure (e.g., through a cellular network) to direct mode communications (e.g., a communication path directly between two communication devices). For example, in switching from an infrastructure mode communication path to a direct mode communication path, a method may include: determining a public-facing address corresponding to the infrastructure path; replacing, for a packet that is to be transmitted over the direct mode communication path to a second communication device, a source address field of the packet with the determined public-facing address; and encapsulating the packet with source and destination address fields corresponding to the first and second communication device through the direct mode communication path respectively.

  • Patent number: 9756098
    Abstract: Some embodiments provide a multi-tenant over-the-top multicast solution that integrates the per user stream customizability of unicast with the large scale streaming efficiencies of multicast. The solution involves an application, different multicast groups streaming an event with different customizations, and a manifest file or metadata identifying the different groups and customizations. The solution leverages the different multicast groups in order to provide different time shifts in the event stream, different quality level encodings of the event stream, and different secondary content to be included with a primary content stream. The application configured with the manifest file or metadata dynamically switches between the groups in order to customize the experience for a user or user device on which the application executes. Switching from multicast to unicast is also supported to supplement available customizations and for failover.

  • Patent number: 9743339
    Abstract: Various embodiments implement a set of low overhead mechanisms to enable on-demand routing protocols. The on-demand protocols use route accumulation during discovery floods to discover when better paths have become available even if the paths that the protocols are currently using are not broken. In other words, the mechanisms (or “Route Optimizations”) enable improvements to routes even while functioning routes are available. The Route Optimization mechanisms enable nodes in the network that passively learn routing information to notify nodes that need to know of changes in the routing information when the changes are important. Learning routing information on up-to-date paths and determining nodes that would benefit from the information is performed, in some embodiments, without any explicit control packet exchange. One of the Route Optimization mechanisms includes communicating information describing an improved route from a node where the improved route diverges from a less nearly optimal route.
