摘要

A common shortcoming of many network measurement programs is thatntheir metrics are not expressed in terms directly applicable tonapplications and users. To address this problem, we have developed thenIP Benchmark (IPB), a benchmark program that synthetically generatesntraffic to simulate the network activity of common Internetnapplications. It measures the performance experienced by the simulatednapplications, and expresses that performance in terms ofnapplication-specific metrics. After presenting same details of thendesign and implementation of IPB, we show how we use it to measure HTTPnperformance along various long-delay, lossy ATM links, such as might benfound in satellite or wireless ATM environments. These links themselvesnare simulated by using a BBN Long Link Emulator which adds delays andnerrors to local-area OC-3 links. Finally, we present some preliminarynresults
