  • Patent number: 9887874
    Abstract: In one embodiment, a plurality of paths in a network from a source device to a destination device is identified. A predicted performance for packet delivery along a primary path from the plurality of paths is determined. The predicted performance for packet delivery along the primary path is then compared to a performance threshold. Traffic sent along the primary path may be duplicated onto a backup path selected from the plurality of paths based on a determination that the predicted performance along the primary path is below the performance threshold.

    Abstract: In one embodiment, a first device in a network receives application traffic sent from a source device towards a destination address. The first device sends the application traffic to a traffic identification service. The first device receives an instruction to establish a network tunnel to send the application traffic from the source device towards the destination address. The instruction is based on a classification of the application traffic by the traffic identification service. The first device establishes the network tunnel to send the application traffic from the source device towards the destination address.

  • Patent number: 9887881
    Abstract: Techniques are disclosed for classifying a network flow based on a domain name system (DNS) request. Embodiments receive a first DNS request associated with establishing a network flow with a remote service. Here, the first DNS request specifies a domain name associated with the remote service. The domain name is analyzed in order to determine a first classification for the remote service. The first classification is selected from a plurality of classifications. Embodiments then determine a network management policy to apply to the network flow, based on the determined first classification.

  • Patent number: 9882806
    Abstract: Techniques are disclosed for exchanging anonymized information between autonomous systems. In one example, a method comprises accessing an eigenvalue, wherein the eigenvalue is based on topology data associated with the first autonomous system; encoding the eigenvalue into a message; and transmitting, by a network element located in the first autonomous system, the message to an external edge router located in the second autonomous system. A further method can comprise receiving, by a network component located in a first autonomous system, a message, wherein the message comprises an eigenvalue and the message is received from an external network element located in a second autonomous system; accessing another other eigenvalue, the another eigenvalue corresponding to an autonomous system different from the first autonomous system; analyzing the another eigenvalue and the eigenvalue; and executing, by the network element, an action based on the analyzing.

  • Patent number: 9882964
    Abstract: One embodiment provides a system that facilitates explicit strategy feedback in a Content-Centric Network (CCN). During operation, the system sends a first interest associated with an explicit strategy feedback request via an egress interface. This egress interface is in a plurality of egress interfaces associated with a same name in a forwarding table. An interest is location-independent and uniquely identifies the content object in the CCN and is routed based on the name in the CCN. The system stores one or more parameters received in response to the explicit strategy feedback request in an entry, which includes the name and the egress interface, in the forwarding table. The one or more parameters are associated with a first device. The system determines, for a second interest for a content object associated with the name, an egress interface from the plurality of egress interfaces based on the stored parameters.

  • Patent number: 9883507
    Abstract: In one embodiment, a particular node operates a distributed routing protocol in a shared-media communication network, and distributes timeslot allocations using the routing protocol, where the particular node as a parent node allocates a pool of timeslots available to child nodes of the parent node. The parent node specifically allocates particular timeslots from the pool to particular child nodes according to particular flows from a source to a target in the shared-media communication network in order to meet a defined time budget for a resultant time-synchronized path from the source to the target.

  • Patent number: 9882904
    Abstract: Protocol status information is used to perform traffic filtering by dropping messages that are not consistent with the protocol status information. In one embodiment, a method involves comparing message information and protocol status information. The message information is associated with a first message. The protocol status information is obtained in response to one or more second messages, which are conveyed according to a protocol used to assign network addresses to clients. The method also involves determining whether to discard the first message, based on an outcome of the comparison of the message information and the protocol status information. For example, it can be determined that the first message should be discarded, if the message information does not match the protocol status information.

  • Patent number: 9883143
    Abstract: A video conference endpoint includes a camera to capture video and a microphone array to sense audio. One or more preset views are defined. Images in the captured video are processed with a face detection algorithm to detect faces. Active talkers are detected from the sensed audio. The camera is controlled to capture video from the preset views, and from dynamic views created without user input and which include a dynamic overview and a dynamic close-up view. The camera is controlled to dynamically adjust each of the dynamic views to track changing positions of detected faces over time, and dynamically switch the camera between the preset views, the dynamic overview, and the dynamic close-up view over time based on positions of the detected faces and the detected active talkers relative to the preset views and the dynamic views.
