Emerging large-scale scientific applications have a critical need for high bandwidth and predictableperformance network service. The OptIPuter project is pioneering a radical, new type of distributed application paradigm which 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 highquality, dedicated network

In this article, we compare the OptIPuter's approach (DVC) which exploits network resources to deliver higher-quality network services with several alternative service models (intelligent network and asynchronous file transfer). Our simulations show that there are significant differences amongst 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.
