Work Load Design for NFV performance evaluation Intel Mobile Communications SG1 NIP#29 1

Background NFV enables use of high- volume servers to reduce TCO NFV is under standardization within ETSI technology cluster NFV evaluation is a crucial business need Multiple Stakeholders in the Telecom Ecosystem that are involved in the evaluation 2 Service Providers EPC Vendors IaaS Vendors Compute Element Vendors

NFV as an Active Research Topic Active Research to study multiple aspects of virtualization Characterizing performance of NFV [2] Understanding bottlenecks in NFV [3] Evaluation of architecture and infrastructures using NFV [4] References [2] Hirschman B., Mehta P., et.al., “High-performance evolved packet core signaling and bearer processing on general-purpose processors”, IEEE Network, Pages 6-14, 2015, Vol. 29, Issue. 3.

Importance Performance on virtualized cores vary for different workloads Important to evaluate performance for – Planning infrastructure deployment – Network roll-out – Business decisions There is no standardized framework for exchange of work- load descriptions between the various stakeholders to enable an effective performance evaluation 4
