  • Patent number: 9686194
    Abstract: One embodiment provides a system that forwards a packet with a hierarchically structured variable-length identifier (HSVLI) in a network. An HSVLI indicates a piece of content and indicates a hierarchical structure of contiguous components ordered from a most general level to a most specific level. The length of the HSVLI is not fixed. During operation, the system receives a packet which contains an interest for a piece of content with an HSVLI. Subsequently, the system determines forwarding information for the HSVLI based on one or more of: knowledge of content which matches the HSVLI, a forwarding policy, and contextual information about the network. Next, the system configures a forwarding engine with the forwarding information. The system then forwards the packet based on the forwarding information.

  • Patent number: 9232180
    Abstract: A method and apparatus for controlling data transmission via user-maintained modes is provided. A first audio data stream is recorded on a transmitting electronic apparatus. A second audio data stream is stored on the transmitting electronic apparatus. Transmission of one of the first and the second audio data streams is controlled via a first user-maintained mode when at least the other of the first and the second audio data streams is being transmitted to the electronic apparatus. The one of the first and the second audio data streams is transmitted to a receiving electronic apparatus and the other of the first and the second audio data streams is suspended.

  • Patent number: 8676572
    Abstract: A computer-implemented system and method for enhancing audio to individuals participating in a conversation is provided. Audio data for individuals participating in one or more conversations is analyzed. Possible conversational configurations of the individuals are generated based on the audio data, and each possible conversational configuration includes one or more subconfigurations of at least two of the individuals. A probability weight is assigned to each of the subconfigurations and includes a likelihood that the individuals of that subconfiguration are participating in one of the conversations. A probability of each possible conversational configuration is determined by combining the probability weights for the subconfigurations of that possible conversational configuration. The possible conversational configuration with the highest probability is selected as a most probable configuration. The individuals participating in the conversations are determined based on the most probable configuration.

  • Patent number: 8561179
    Abstract: One embodiment of the present invention provides a system for identifying undesirable features in a network of computers. During operation, the system detects an anomaly associated with a node in the network. Next, the system identifies one or more features which are associated with the anomaly. The system then updates the identified features. Next, the system communicates the information corresponding to updated features to at least one other node in the network. The system then receives information indicating a correlation between the updated features and the anomaly from at least one other node in the network. Next, the system correlates the updated features with the anomaly based on the received information. The system subsequently produces a result which indicates a correlation between the updated features and the anomaly.

  • Patent number: 8463600
    Abstract: A system and method for automatically adjusting floor controls based on conversational characteristics is provided. Audio streams are received, which each originate from an audio source. Floor controls for a current configuration including at least a portion of the audio streams are maintained. Conversational characteristics shared by two or more of the audio sources are determined. Possible configurations for the audio streams are identified based on the conversational characteristics. An analysis of the current configuration and the possible configurations is performed. A change threshold comprising a minimum number of timeslices for at least one of the current configuration and one of the possible configurations is applied to the analysis. When the analysis satisfies the change threshold, the floor controls are automatically adjusted. The audio streams are mixed into one or more outputs based on the adjusted floor controls.

  • Patent number: 8375436
    Abstract: One embodiment of the present invention provides a system for facilitating session migration. During operation, the system receives a communication packet from a client destined to a remote server. The system determines whether the communication packet belongs to a pre-existing communication session, and whether session state information associated with the session is available locally. In response to the communication packet belonging to a pre-existing communication session and the session state information being unavailable locally, the system constructs an interest requesting the session state information, disseminates the interest over a network, and receives the session state information.

  • Patent number: 8243735
    Abstract: One embodiment provides a system for forwarding packets with hierarchically structured variable-length identifiers (HSVLIs), wherein the computer includes a processor. During operation, the system converts an HSVLI into a number of fixed-length addresses, wherein the HSVLI indicates a piece of content and is hierarchically structured, and comprises contiguous components ordered from a most general level to a most specific level. In addition, the length of a respective HSVLI is not fixed. The system further performs an effective longest-prefix-match lookup by performing multiple exact-match lookups based at least on the fixed-length addresses.

  • Patent number: 8244881
    Abstract: One embodiment of the present invention provides a system for facilitating network service virtualization. During operation, the system receives a service request from a client, and initializes a communication session with the client. The system constructs an interest using session state information that can identify the client and/or a previous communication session. The interest comprises a hierarchically structured variable-length name. The system then broadcasts the interest to a number of servers. The system subsequently forwards to the client data received from a server which responds first to the interest.

  • Patent number: 8160069
    Abstract: One embodiment provides a system that receives a packet with a hierarchically structured variable-length identifier (HSVLI). An HSVLI indicates a piece or collection of content and may be hierarchically structured, comprising contiguous components ordered from a most general level to a most specific level. The length of a respective identifier is not fixed. During operation, the system converts the HSVLI into a fixed-length key. Subsequently, the system obtains forwarding information based on one or more longest-prefix matches with a longest-prefix-match lookup engine using the fixed-length key. Next, the system forwards the packet to an output port based on the forwarding information.
