【摘要】 给出虚拟实验室的一般定义。在此基础上,提出基于远程控制与共享的虚拟实验室的网络结构,即通过网关机制,实现低层控制网络与Internet的互连。从分析现有Internet基本运行机制入手,指出了它用于远程控制存在的主要缺陷,并在网络拥塞控制机制方面,提出了一些改进算法。运用目前国际流行的网络研究工具——VINT,进行了仿真研究。更多还原

【Abstract】 We present a general definition of the virtual lab, and the network architecture of virtual lab based on remote control and sharing. Using the gateway mechanism, the interlink between lower control network and Internet was implemented. We indicate some limitation on Internet when it is applied to the remote control in virtual lab and present an improved algorithm on network congestion control. The algorithm is simulated by VINT (Virtual Internet Testbed).更多还原
