The Benchmarking Methodology Working Group (BMWG) will continue to
produce a series of recommendations concerning the key performance
characteristics of internetworking technologies, or benchmarks for
network devices, systems, and services. Taking a view of networking
divided into planes, the scope of work includes benchmarks for the
management, control, and forwarding planes. 

The scope of BMWG has been extended to develop methods for
virtual network functions (VNF) and their unique supporting 
infrastructure (such as SDN Controllers and vSwitches). 
Benchmarks for platform capacity and performance characteristics 
of virtual routers, firewalls (and other security functions), 
signaling control gateways, and other forms of gateways are included.  
The benchmarks will foster comparisons between physical and virtual 
network functions, and also cover unique features of  
Network Function Virtualization systems. Also, with the emergence
of virtualized test systems, specifications for test system
calibration are also in-scope.

Each recommendation will describe the class of network function, system, 
or service being addressed; discuss the performance characteristics that
are pertinent to that class; clearly identify a set of metrics that aid
in the description of those characteristics; specify the methodologies
required to collect said metrics; and lastly, present the requirements
for the common, unambiguous reporting of benchmarking results.

The set of relevant benchmarks will be developed with input from the
community of users (e.g., network operators and testing organizations)
and from those affected by the benchmarks when they are published
(networking and test equipment manufacturers). When possible, the
benchmarks and other terminologies will be developed jointly with
organizations that are willing to share their expertise. Joint review
requirements for a specific work area will be included in the
description of the task.

To better distinguish the BMWG from other measurement initiatives in the
IETF, the scope of the BMWG is limited to the characterization of
implementations of various internetworking technologies
using controlled stimuli in a laboratory environment. Said differently,
the BMWG does not attempt to produce benchmarks for live, operational
networks. Moreover, the benchmarks produced by this WG shall strive to
be vendor independent or otherwise have universal applicability to a
given technology class.

Because the demands of a particular technology may vary from deployment
to deployment, a specific non-goal of the Working Group is to define
acceptance criteria or performance requirements.

An ongoing task is to provide a forum for development and
advancement of measurements which provide insight on the
capabilities and operation of implementations of inter-networking 
technology. Ideally, BMWG should communicate with the operations 
community through organizations such as NANOG, RIPE, and APRICOT, and 
consult with/inform other IETF WGs (as is the current practice).
