    摘要: A method and an apparatus for sending a key on a Wireless Local Area Network (WLAN) is provided. In a scenario where an Access Server is separate from an Access Controller, the Access Controller may send a master key of a specified WLAN station to the AC and trigger the AC to agree with the station on a transient key. The method includes: when receiving the master key of the WLAN station sent from an AAA server, searching a station information table for an IP address of an AC associated with the station; sending a message to the AC to instruct the AC to perform a 4-way handshake with the station to agree on a transient key, where the third message carries the master key of the station, a 4-way handshake triggering bit, and a MAC address of the WLAN station.

    摘要: A system and method for providing media streaming are provided. A media description file having a range string indicator is used to specify location offsets of a plurality of media fragments within a media file. The range string may be stored directly in the media description file or the media description file may contain an indicator specifying a file containing the range string. The media description file may also include a range unit specifying the size of the offsets in the range string. In an embodiment, offsets within the individual media fragments may also be provided, either in the media description file or in a different file.
