Re: [bmwg] WG Action: Rechartered Benchmarking Methodology (bmwg)

["MORTON, ALFRED C (AL)" <[e-mail]>]

We made it this far!  Everything we asked to do is in there.
Let's get to work and meet our milestones.

> divided into planes, the scope of work includes benchmarks for the

> 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

> 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 detailed

> 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.

> The BMWG is explicitly tasked to develop benchmarks and methodologies

> 
> BGP Control-plane Convergence Methodology (Terminology is complete):
> With relevant performance characteristics identified, BMWG will prepare
> a Benchmarking Methodology Document with review from the Routing Area
> (e.g., the IDR working group and/or the RTG-DIR). The Benchmarking
> Methodology will be Last-Called in all the groups that previously
> provided input, including another round of network operator input during
> the last call.
> 
> SIP Networking Devices: Develop new terminology and methods to
> characterize the key performance aspects of network devices using
> SIP, including the signaling plane scale and service rates while
> considering load conditions on both the signaling and media planes. This
> work will be harmonized with related SIP performance metric definitions
> prepared by the PMOL working group.
> 
> Traffic Management: Develop the methods to characterize the capacity
> of traffic management features in network devices, such as
> classification,
> policing, shaping, and active queue management. Existing terminology
> will be used where appropriate. Configured operation will be verified
