Abstract: Obfuscating a human or other subject in digital media preserves privacy. A user of a smartphone, for example, may enable a flag for obscuring her face in digital photos or movies. When any device captures digital media, the user's smartphone transmits the flag for receipt. The device capturing the digital media is thus informed of the user's desire to obscure her face or even entire image. The device capturing the digital media may thus perform an obscuration in response to the flag.

Abstract: A cache server for providing content includes a processor configured to receive a first datagram from a client system sent to an anycast address, send a response datagram to the client system in response to the first datagram, receive a request datagram from the client system sent to the anycast address, and send a batch of content datagrams to the client system. The first datagram includes a universal resource locator corresponding to the content. The response datagram includes a content identifier for the content. The request datagram includes the content identifier, an offset, and a bandwidth indicator. The batch of content datagrams includes a portion of the content starting at the offset.

Abstract: A system that incorporates teachings of the present disclosure may include, for example, initializing a boundary estimate for an optimization of a linear programming model describing a network of media servers for servicing requests for media content items from subscriber devices, where the boundary estimate is an estimate of an infeasible solution of the linear programming model, and calculating iteratively, using an exponential potential function, additional boundary estimates for the linear programming model, wherein the calculating resolves to an improved boundary estimate that corresponds to placement of copies of the media content items at the media servers subject to a set of constraints on storage capacity of media servers and on bandwidth for communication links in the network. Other embodiments are disclosed.

Abstract: A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor.

Abstract: A method includes forecasting demand for media content items of a media distribution system based on historical demand information to generate forecasted demand. The method includes generating a mixed integer program model based on storage constraints of a plurality of distribution nodes of the media distribution system, bandwidth constraints of the media distribution system, and the forecasted demand. The method includes performing a Lagrangian relaxation operation using the mixed integer program model. The method includes determining values of a cost function based on a result of the Lagrangian relaxation operation. The method includes assigning each of the media content items to a corresponding distribution node of the plurality of distribution nodes based on the cost function and the forecasted demand.

Abstract: Methods and apparatus to migrate a mobile device from a first virtual private mobile network to a second virtual private mobile network are disclosed. An example apparatus includes a processor and a memory including instructions that cause the processor to perform operations including determining, based on a set of latency routing rules, that a communication transmitted via the first virtual private mobile network is a latency sensitive communication. In response to determining the communication is a latency sensitive communication, the mobile device that originated the latency sensitive communication is identified. The mobile device is communicating via the first virtual private mobile network. Example operations also include migrating the mobile device from the first virtual private mobile network to the second virtual private mobile network wherein the second virtual private mobile network is configured to reduce the latency of the latency sensitive communication.

Abstract: Methods and apparatus to configure virtual private mobile networks are disclosed. Example methods include provisioning a virtual private mobile network within a wireless network, and, after provisioning the virtual private mobile network, determining whether a first communication from a user equipment matches a security event profile. When the first communication matches the profile, the example methods include transmitting, from the wireless network via a first base transceiver station, an instruction to cause the user equipment to be communicatively coupled to the virtual private mobile network. The example methods further include instructing the user equipment to transmit a second communication through a second base transceiver station that is physically separate from the first base transceiver station and through the virtual private mobile network. In the example methods, the virtual private mobile network is isolated in a wireless spectrum from other portions of the network.
