摘要： Techniques for securely and adaptively delivering multimedia content are disclosed in which a set of alternate access units for each time slot is obtained. Then, the encryption stream index of each access unit from the set of alternate access units of the previous time slot are obtained. An encryption stream index is then assigned to each access unit in the set of alternate access units in the current time slot, such that the encryption index increases over time. Thus, the invention overcomes the problem of encrypting a multimedia stream that may have multiple access units for each time slot by selecting the encryption index for each access unit such that the encryption index increases, regardless of which access unit the delivery system (e.g., server) selects for transmission.

摘要： Disclosed is a method, upstream processing node, and computer readable medium for processing data packets. The method includes receiving an allocation for at least one computing resource. At least one data packet at one or more upstream processing elements in an upstream processing node is received. The method also includes determining if at least one output queue of the upstream processing elements includes available space for processing of the data packet. The data packet is processed in response to the output queue including available space to form a resulting data packet. The method further includes determining that an input queue of at least one downstream processing element of a plurality of downstream processing elements includes available space for receiving the resulting data packet In response to the determining, the resulting data packet is transmitted from the upstream processing element to the downstream processing element.

摘要： Disclosed are a method and a computer program storage product for dynamically stabilizing a stream processing system. The method includes receiving at least one computing resource allocation target. A plurality of downstream processing elements and an upstream processing element are associated with at least one input buffer. Each of the downstream processing elements consumes data packets produced by the upstream processing element received on an output stream associated with the upstream processing element. A fastest input rate among each downstream processing element in the plurality of downstream processing elements is identified. An output rate of the upstream processing element is set to the fastest input rate that has been determined for the plurality of downstream processing elements.
