Abstract: A method in an electronic device provides local content to a user device in a communication network. The communication network includes an access network and a core network. In the access network, a content request is intercepted from the user device, which may be formatted according to a network interface. The content request may include a request for data content. Protocol layers associated with an active data session may be terminated so that an edge gateway device may extract and inject packets into the data stream without involving the core network. A cache may be maintained in the access network.

Abstract: Graphical programming or modeling environments, such as a block diagram environment, are disclosed in which dependencies that influence how a model executes are defined without altering the visual representation of the model. In the graphical modeling or programming environment, users create a model that describes how the system is to execute. The users can then augment the model with non-graphical dependencies that provide general execution goals or specific dependencies between blocks. The user can augment the graphical model with dependency constraints specifying how the model should execute. The constraints are coupled to the model and can be optionally displayed on the model in a debugging/analysis mode to provide further insight into how the model executes.
