Adaptive packet sampling for flow volume measurement
2002
Computer communication review
Preserved Fulltext
In this paper we propose and analyze an adaptive, stratified random packet sampling technique for flow-level traffic measurement. ...
With high-speed Internet backbone links, efficient and effective packet sampling techniques for traffic measurement and monitoring are not only desirable, but also increasingly becoming a necessity. ...
There are several challenging issues in packet sampling for flow-level measurement. In this section we provide an overview of these challenges and our proposed approach.
A. ...
