摘要： A receiver monitoring the transmissions of a packet processing device such as a wireless access point analyzes the monitored transmissions to estimate the probability of packet loss due to buffer overflow in the processing device. The loss probability can be estimated for individual packets to follow rapid changes in communication conditions. An indication of the estimated loss probability can be used to adapt the forward error correction (FEC) parameters that are used to generate the packets, thereby improving the reliability of data delivery to a receiver while optimizing the use of communication channel bandwidth.

摘要： Information is associated with media content. Upon an upload of a portion of the media content, a media fingerprint is derived therefrom. The media fingerprint includes a unique representation of the media content portion, which is derived from a characteristic component of the media content portion. The information is associated with the media content portion based on the derived media fingerprint. Upon streaming the media content portion, the associated information is linked and presented in real time with the media content portion. Upon upload of the media content portion, the media fingerprint may be derived therefrom at upload time or at any time subsequent to upload time and prior to presentation time. The media content may comprise an original instance of content or a derivative instance of the original content.

摘要： Processors that encrypt frames of data representing images and sounds, for example, use a first encryption process to encrypt control data that includes selected data from the data frames and use a second encryption process to encrypt non-selected data from the data frames. The first encryption process is responsive to a key, which may be associated with an intended recipient of the data frames. The second encryption process is responsive to a key that is obtained or derived from the control data. The encrypted control data and the encrypted non-selected data may be delivered to a receiver using separate media. The receiver recovers the data frames using decryption processes that are inverse to the first and second encryption processes. Efficient implementations of the second encryption process are disclosed.

摘要： A target hash value is identified. Identifying a target hash values includes computing a query hash value, partitioning the query hash value into at least a first portion and a second portion, and locally assigning weak bits within the first portion of the query hash value and weak bits within the second portion of the query hash value. The method further includes determining one or more variations of the query hash value with toggling one or more weak bits in the first portion and one or more weak bits in the second portion of the query hash value; and identifying a target hash value that is identical to a variation of the query hash value.

摘要： A method of processing a call request to a callee in a network telephony system is provided which includes mapping a hostname portion of a callee address to a canonical form of the hostname and determining a canonical form of a usemame portion of a callee address. The canonical form of the user identity of the callee is then used as an index to a user database to retrieve a callee database record. The callee database record is then used to determine call routing based on the retrieved callee database record, such as user location, preferences and policy data stored in the record. The method is generally performed by a signaling server in the network, such as a SIP proxy server. The signaling server can also provide security features such as caller authentication. A scalable signaling and routing architecture is also provided.
