摘要

在具有软实时约束的多媒体系统中，必须保证任务具有一定的系统带宽，以便为用户提供可接受的性能。本文提出了一种带宽交换(BWE)协议来管理CPU带宽预留系统上运行的任务之间的资源共享问题。该方法改进了早期的协议带宽继承(BWI)，因为它不仅在独立的任务组之间提供带宽隔离，而且在同一资源共享组内的任意两个任务之间也提供带宽隔离。因此，BWE提供了比BWI更公平的资源分配。

BWE: a resource sharing protocol for multimedia systems with bandwidth reservation

In multimedia systems with soft real-time constraints, tasks must be guaranteed a certain system bandwidth so they can provide an acceptable performance to their users. In this paper a bandwidth exchange (BWE) protocol is proposed to manage resource sharing issues between tasks running on systems with CPU bandwidth reservation. The approach improves an earlier protocol, bandwidth inheritance (BWI), in that it provides bandwidth isolation not only between independent groups of tasks, but also between any two tasks within the same resource sharing group. BWE thus provides fairer resource allocation than BWI.
