Abstract
This paper presents the design, implementation and trials of a-clink, which is a hop-by-hop performance estimation tool based on active networks. The paper begins by analyzing different alternatives of hop-by-hop performance estimation tools: pathchar, clink, pchar and nettimer. Based on this analysis, several deficiencies are identified on the different tools. In order to improve the efficiency and accuracy of the estimations, one of the tools is selected, clink, to design an extension based active network technology. This extension, a-clink, has been implemented over the public domain active network platform SARA. The implementation of a-clink has been trialed on a simple active network prototype spanning two universities connected through public Internet, and its results compared with those obtained by the original clink. The paper concludes describing the advantages of the active version of clink over the conventional passive performance estimation tool.
