面向SOA关键型系统的混合关键度驱动自适应资源管理

针对运行于开放、不确定环境下的SOA架构的多使命复杂关键型系统，提出了一种以混合关键度为驱动的动态分级自适应资源分配算法。它通过构造闭环反馈的分布式控制环，在线动态调整任务Qos，针对不同关键度的任务动态调整资源分配。该方法不但在统计意义上确保了关键型系统的实时性，而且实验证明该方法能有效提高系统在高负载条件下的实际资源利用率和降低关键任务的死线错过率，保证了关键型系统的高可靠性。

Mix-criticality Driven QoS Adaptive Resource Management for SOA-based Critical Systems

SOA-based distributed and embedded safety & mission system(DESMCS) executes in open environments which have different dependability requirements.This paper presented a novel mix-criticality driven QoS adaptive dynamic resource management architecture,which provides middleware services for QoS-and criticality-based resource allocation and adaptation across heterogeneous computing nodes and communication networks.The architecture presented in this paper overcomes the disadvantages of traditional feedback-base...
