Abstract: A system and method relate to determining am initial buffer size associated with a buffer and modifying the initial buffer size when jitter is detected. The initial buffer size may be determined and modified based on a maximum initial buffer size, and the maximum initial buffer size may be determined based on delays associated with storing data to the buffer. For example, the maximum initial buffer size may correspond to a quantity of data that can be stored to the buffer during a maximum acceptable buffering delay. The maximum acceptable buffering delay may be identified by determining drop rates associated with different buffering delays and selecting, as the maximum acceptable buffering delay, one of the buffering delays associated with a maximum acceptable drop rate.

Abstract: A method includes monitoring a bandwidth currently available for streaming of a segment file pertaining to the selected content asset from a server to the client.

Abstract: Systems and methods for improving the efficiency of propagating electronic messages are provided. In some embodiments, a feed of activities on a network such as an online social network (OSN) is analyzed to determine influenced activity probabilities and intrinsic activity probabilities for participants in the network. A Helmhotz Green's Function matrix is determined in order to calculate an overall influence weight for each participant in the network. A Woodbury-Sherman-Morrison formula may be used to accelerate computation of the Helmholtz Green's Function matrix, thus allowing efficient updates to the overall influence weights based on newly monitored activities. The participants with the highest overall influence weights may be selected to propagate a new message, thus providing the greatest likely distribution of the message with the fewest originating transmissions.
