Abstract: A bandwidth measurement method includes sending a first test packet on a test path that includes a to-be-measured link, sending a second test packet on the test path, setting at least one of a quantity of label layers in a first segment routing (SR) label or a quantity of label layers in a second SR label as a reference quantity of label layers for bandwidth measurement, and determining an available bandwidth on the to-be-measured link based on the reference quantity of label layers in response to the to-be-measured link failing to be congested with first test packets and being congested with second test packets. The first test packet includes the first SR label that indicates a forwarding relationship of the first test packet on the to-be-measured link. The second test packet includes a second SR label that indicates a forwarding relationship of the second test packet on the to-be-measured link.

Abstract: Embodiments of the present invention provide a streaming media segment preparation method and apparatus. The method includes: determining at least one quality point, where the at least one quality point is separately used to indicate quality of at least one target segment of streaming media in a first time period; and determining, according to the at least one quality point, the at least one target segment of the streaming media in the first time period. In the embodiments of the present invention, streaming media segments are prepared by taking a quality factor of the streaming media segments into consideration, which may avoid the problem that redundant segments are generated during preparation of the streaming media segments according to bit rates, thereby reducing a storage volume of a server.
