A Hyperlink-directed Data Dissemination Scheme Suite

In data dissemination to a large client population using a broadcast medium, data items are inevitably serialized over the medium and thus a scheduling strategy that determines the data transfer sequences should be developed. The resulted data provision intended to satisfy multiple clients at the same time insists that client local storage should be utilized as data cache to compensate the gap between the broadcast schedule and a single user’s behavior. This paper suggests that the application characteristics should be examined and exploited when designing data dissemination schemes; Dominating data broadcast applications depend on hyperlinks for movement between information pages, which definitely restricts the sequence of data requests. Inspired by this observation, we propose a scheduling mechanism that deals with users of different interests in a fair manner but does not sacrifice the response time, and a cache management that significantly lowers the response time by raising cache hit ratio.
