| | 167 | |
| | 168 | In our proposed SDN measurement framework, called iSTAMP, the flexibility provided by the SDN for real-time reconfiguration of OpenFlow switches is utilized to partition the TCAM entries of switches/routers into two parts to: 1) optimally aggregate part of incoming flows for aggregate measurements, and 2) de-aggregate and directly measure the most informative flows for per-flow measurements. Under hard resource constraint of TCAM entries in SDN switches, iSTAMP designs the optimal aggregation matrix which minimizes the flow-size estimation error via using compressive sensing network inference techniques. Moreover, the iSTAMP framework utilizes an intelligent Multi-Armed Bandit based algorithm to adaptively sample the most ”rewarding” flows, whose accurate measurements have the highest impact on the overall flow measurement and estimation performance. iSTAMP then processes these aggregate and per-flow measurements to effectively estimate network flows using a variety of optimization techniques. |
