Resource/accuracy tradeoffs in software-defined measurement

Masoud Moshref, Minlan Yu, Ramesh Govindan
2013 Proceedings of the second ACM SIGCOMM workshop on Hot topics in software defined networking - HotSDN '13  
In this paper, we first qualitatively discuss the tradeoff space of resource usage versus accuracy for these different primitives as a function of the spatial and temporal measurement granularity, then  ...  Previous work on network measurements have explored several primitives of increasing complexity for measurement tasks at individual nodes, ranging from counters to hashing to arbitrary code fragments.  ...  Software-defined networks can enable programmable measurement in networks [21] . In this software-defined measurement approach, multiple measurement tasks can execute concurrently.  ...
