新兴的大规模科学应用迫切需要高带宽和可预测性能的网络服务。OptIPuter项目正在开创一种全新的分布式应用范例，它利用专用的光学电路来紧密耦合地理上分散的资源。这些专用光路按需建立，并与终端资源结合，形成分布式虚拟计算机（DVC）。DVC为应用程序提供高质量的专用网络服务。在这篇文章中，我们比较OptIPuter的方法（DVC），它利用网络资源提供更高质量的网络服务，几种替代服务模型（智能网络和异步文件传输）。我们的模拟结果表明，有显着的差异模型之间的资源利用率和交付的应用服务。关键的要点包括OptIPuter方法为应用程序提供了上级网络服务（如新兴的电子科学应用程序和性能关键型分布式应用程序所需），但以网络资源消耗为代价。其他方法使用较少的网络资源，但提供较低质量的应用服务。
Emerging large-scale scientific applications have a critical need for high bandwidth and predictable-performance network service. The OptIPuter project is pioneering a radical new type of distributed application paradigm that exploits dedicated optical circuits to tightly couple geographically dispersed resources. These private optical paths are set up on demand and combined with end resources to form a distributed virtual computer (DVC). The DVC provides high-quality dedicated network service to applications. In this article we compare the OptIPuter's approach (DVC), which exploits network resources to deliver higher-quality network services, to several alternative service models (intelligent network and asynchronous file transfer). Our simulations show that there are significant differences among the models in their utilization of resources and delivered application services. Key takeaways include that the OptIPuter approach provides applications with superior network service (as needed by emerging e-science applications and performance-critical distributed applications), at an expense in network resource consumption. The other approaches use fewer network resources, but provide lower-quality application service.
