    摘要： A device, computer program product and a method, the method may include: Extracting first size information about sizes of different frames of a first segment of an encrypted first streaming media flow that has a first CBR. Extracting second size information about sizes of different frames of a second segment of a second streaming media flow that has a second CBR that equals the second CBR. The extracting of the first and second size information and the determining of the relationship are executed without decrypting the first and second encrypted streaming media flows. Determining, based on first and second size information and on the first and second type information, a relationship between qualities of the first and second streaming media flows based on the first and second size information. Extracting first type information indicative of which frame of the first segment is the first reference frame and which frames of the first segment are the first non-reference frames. Extracting second type information indicative of which frame of the second segment is the second reference frame and which frames of the second segment are the second non-reference frames.

    摘要： Apparatus for rating download events is described. The apparatus includes a network interface and a processor. The processor, via the interface, monitors one or more download events in which content is downloaded by one or more users. In response to the monitoring, the processor identifies at least one quantitative property of the download events. Based on the property, the processor assigns a rating to the download events that is indicative of an estimated user-perceived quality of the download events. The processor then generates an output indicative of the rating. Other embodiments are also described.

    摘要： Described embodiments include a system that includes a network interface and a processor. The network interface is configured to receive, at a first time, a packet transmitted from a source communication terminal over a communication network en route to a target communication terminal, before the packet passes through a particular portion of the communication network, and to receive the packet at a second time, after the packet has passed through the particular portion of the communication network. The processor is configured to delay the packet, subsequently to the packet being received at the second time, by a delay duration that is a decreasing function of a duration between the first time and the second time, and to send the delayed packet, subsequently, via the network interface, en route to the target communication terminal. Other embodiments are also described.
