The explosion of mobile devices and content, server virtualization, and advent of cloud services are among the trends driving the networking industry to reexamine traditional network architectures. SoftwareDefined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today’s applications. Currently, it continues to be crucial for businesses to monitor their networks in order to be productive and avoid serious threats from network failures and server downtime, demanding accuracy and timeliness. In this paper, we focus on this trade-off between monitoring accuracy and timeliness. We propose Cheapo – an adaptive algorithm for monitoring frameworks in SDN, which provides an API for flow statistics collection at different aggregation levels. The proposed approach provides highly accurate information without producing unnecessary network traffic.
