摘要
在处理数字音视频数据的分布式系统中，出现了最小预订率问题。问题是找到共享存储系统上必须保留数据的最小速率，以便提供可变速率输出调度的连续缓冲回放。这个问题等价于最小输出速率:给定不同时间段的输入速率，找出缓冲区不溢出的最小输出速率。作者提出了一个O(n log n)随机化算法和一个O(n log n log n)确定性算法
The minimum reservation rate problem in digital audio/video systems
The minimum reservation rate problem arises in distributed systems for handling digital audio and video data. The problem is to find the minimum rate at which data must be reserved on a shared storage system in order to provide continuous buffered play-back of a variable-rate output schedule. The problem is equivalent to the minimum output rate: given input rates during various time periods, find the minimum output rate under which the buffer never overflows. The authors present an O(n log n) randomized algorithm and an O(n log n log log n) deterministic one.<>
