CAREER: Balancing Performance, Security, and Resource Utilization in Wide-Area Distributed Systems

这个项目探索使用分布式计算资源来对抗广域系统固有的不可靠性和高度可变的性能。这项工作的目标是通过使用分布在多个管理域的不准确信息高效地复制和迁移计算，从而平衡广域性能、安全性和资源利用率。为此，本研究解决了对全球网络基础设施进行扩展的三个重要领域：i)用于有效利用全球资源的计算的动态放置和迁移，ii)在同时利用多个管理域中的资源的主体之间的资源分配，以及iii)支持用于广域计算的细粒度权利转移的安全基础设施。这项工作的影响将是提高利用此基础设施的分布式系统的公平性、可伸缩性和容错能力。

This project explores employing distributed computational resources to combat the unreliability and highly variable performance inherent to wide-area systems. The goal of this work is to balance wide-area performance, security, and resource utilization by efficiently replicating and migrating computation using inexact information distributed across multiple administrative domains. To this end, this research addresses three areas important to scaling the global network infrastructure: i) dynamic placement and migration of computation for efficient utilization of global resources, ii) resource allocation among principals simultaneously utilizing resources in multiple administrative domains, and iii) a security infrastructure that enables the fine-grained transfer of rights for wide-area computation. The impact of this work will be increase fairness, scalability, and fault tolerance for distributed systems leveraging this infrastructure.
