Simultaneous Proxy Evaluation

The Simultaneous Proxy Evaluation (SPE) architecture is designed to evaluate multiple web proxies in parallel using object requests which are duplicated and passed to each proxy. The SPE architecture reduces problems of unrealistic test environments, dated and/or inappropriate workloads, and is additionally applicable to content-based prefetching proxies. It is intended to measure byte and object hit rates, client-perceived latencies, and cache consistency. We characterize a space of proxy evaluation methodologies and place this architecture within it.
