Application-Level Policies for Automatic Switching Between Content Redistributors

Overview This paper considers the distribution of live and scheduled multimedia content (e.g., radio or TV broadcasts) through multiple aggregators. An aggregator is an access-controlled redistributor that operates a pool of proxy servers to aggregate content from source content providers and forwards it to mobile hosts. Aggregators package content into channels (e.g., BBC 9 o'clock news) and offer them at various quality levels (e.g., using different encodings) and prices. Mobile hosts receive channels via a 'Beyond 3G' wireless Internet, which consists of different types of wireless networks (e.g., 802.11 and UMTS networks). This paper investigates how a mobile host can switch to another aggregator and an associated quality level while it is receiving a channel.
