Abstract

   This draft describes benchmarking considerations for a containerized
   infrastructure.  In a containerized infrastructure, Virtualized
   Network Functions(VNFs) are deployed on operating-system-level
   virtualization platform by abstracting the user namespace as opposed
   to virtualization using a hypervisor.  Leveraging this, the system
   configurations and networking scenarios for VNF benchmarking will be
   partially changed by way of resource allocation and network port
   binding between a physical host and VNFs.  In this draft we compare
   the state of the art in container networking architecture with
   networking on VM-based virtualized systems, and provide several test
   scenarios for network performance in containerized infrastructure.

1.  Introduction

   The Benchmarking Methodology Working Group(BMWG) has recently
   expanded its benchmarking scope from Physical Network Function(PNF)
   running on dedicated hardware system to Network Function
   Virtualization(NFV) infrastructure and Virtualized Network
   Function(VNF).  [RFC8172] described considerations for configuring
   NFV infrastructure and benchmarking metrics, and [RFC8204] gives
   guidelines for benchmarking virtual switch which connects VNFs in
   Open Platform for NFV(OPNFV).

   Recently NFV infrastructure has evolved to include a lightweight
   virtualized platform called the containerized infrastructure, where
   VNFs share the same host Operating System(OS) and they are logically
   isolated by using a different namespace.  While previous NFV
   infrastructure uses a hypervisor to allocate resources for Virtual
   Machine(VMs) and instantiate VNFs on it, the containerized
   infrastructure virtualizes resources without a hypervisor, therefore
   making containers very lightweight and more efficient in
   infrastructure resource utilization compared to a VM based NFV
   infrastructure.  When we consider benchmarking for VNFs in the
