| 摘 要： | 基于互联网的虚拟计算环境(iVCE)是一种新型网络计算平台.互联网资源的成长性、自治性和多样性等自然特性给iVCE中的资源共享带来巨大的挑战.DHT覆盖网(简称DHT)具有可扩展、延迟低、可靠性高等优点,是iVCE实现资源有效共享的重要途径之一.拓扑构建是DHT的基础性关键技术,实现了DHT的动态维护与消息路由等基本功能.本文首先概述传统DHT的拓扑构建技术,主要包括各种典型DHT的动态维护机制与消息路由算法、支持复杂查询的DHT索引构建技术,以及支持管理域匹配的DHT分组构建技术等;进而针对互联网资源的特点,综述在iVCE中DHT拓扑构建技术的最新研究进展.本文在最后对DHT拓扑构建技术的未来发展方向进行探讨.

| Abstract: | The Internet-based virtual computing environment(iVCE) is a novel network computing platform.The characteristics of growth,autonomy,and diversity of Internet resources present great challenges to resource sharing in iVCE.The DHT overlay(DHT for short) technique has various advantages such as high scalability,low latency,and desirable availability,and is thus an important approach to realizing effcient resource sharing.Topology construction is a key technique for structured overlays that realizes basic overl... |
