Network Performance Benchmarking for Containerized Infrastructure in NFV environment

Recently, container orchestration technology has been widely adopted by telco companies in network function virtualization (NFV) architecture. The communication between containerized virtual network functions (VNFs) is implemented by the networking models which contain switches and router functions in the host system. Different kinds of networking models which support packet acceleration features (OvS-DPDK, VPP, SR-IOV, eBPF, or combination), and different container deployment configurations (CPU isolation, NUMA alignment, service function chaining, inter-node networking technologies) have significant impacts on the performance of container network. This paper aims to accurately benchmark container network performance based on these aspects. Especially, we categorize and cover some missing models and configuration scenarios that were not presented in previous related works.
