Abstract: Techniques are described for facilitating the delivery of digital content using gossip protocols. A group of client devices share information about network conditions in sideband communications using a gossip protocol. Each of the client devices then uses this information to make decisions about how to access content. By providing accurate and current information about network conditions the occurrence of buffering events and/or fatal errors may be significantly reduced or eliminated.

Abstract: Techniques for delivering content are described that vary the bit rate with which the content is delivered to achieve a consistent level of quality from the user's perspective. This is achieved through the use of quality metrics associated with content fragments that guide decision making in selecting from among the different size fragments that are available for a given segment of the content. Fragment selection attempts to optimize quality within one or more constraints.
