Inferring router statistics with IP timestamps
Andrew D. Ferguson, Rodrigo Fonseca · 2010
This paper describes our initial experiences with using the IP timestamp option to infer router statistics such as traffic shape and CPU load. By deducing this information through the use of an IP option, we can gather these statistics without administrative access to the router under study. This creates the potential for researchers to gather basic statistics from routers in wide-area networks which support this option.
