- <section title="Introduction">
- <t>Benchmarking Methodology Working Group (BMWG) has traditionally
- conducted laboratory characterization of dedicated physical
- implementations of internetworking functions. The Black-box Benchmarks
- of Throughput, Latency, Forwarding Rates and others have served our
- industry for many years. Now, Network Function Virtualization (NFV) has
- the goal to transform how internetwork functions are implemented, and
- therefore has garnered much attention.</t>
-
- <t>This memo describes the progress of the Open Platform for NFV (OPNFV)
- project on virtual switch performance characterization, "VSWITCHPERF".
- This project intends to build on the current and completed work of the
- Benchmarking Methodology Working Group in IETF, by referencing existing
- literature. For example, currently the most referenced RFC is <xref
- target="RFC2544"/> (which depends on <xref target="RFC1242"/>) and
- foundation of the benchmarking work in OPNFV is common and strong.</t>
-
- <t>See
- https://wiki.opnfv.org/characterize_vswitch_performance_for_telco_nfv_use_cases
- for more background, and the OPNFV website for general information:
- https://www.opnfv.org/</t>
-
- <t>The authors note that OPNFV distinguishes itself from other open
- source compute and networking projects through its emphasis on existing
- "telco" services as opposed to cloud-computing. There are many ways in
- which telco requirements have different emphasis on performance
- dimensions when compared to cloud computing: support for and transfer of
- isochronous media streams is one example.</t>
-
- <t>Note also that the move to NFV Infrastructure has resulted in many
- new benchmarking initiatives across the industry, and the authors are
- currently doing their best to maintain alignment with many other
- projects, and this Internet Draft is evidence of the efforts.</t>
- </section>
-
- <section title="Scope">
- <t>The primary purpose and scope of the memo is to inform BMWG of
- work-in-progress that builds on the body of extensive literature and
- experience. Additionally, once the initial information conveyed here is
- received, this memo may be expanded to include more detail and
- commentary from both BMWG and OPNFV communities, under BMWG's chartered
- work to characterize the NFV Infrastructure (a virtual switch is an
- important aspect of that infrastructure).</t>
- </section>
-
- <section title="Benchmarking Considerations">
- <t>This section highlights some specific considerations (from <xref
- target="I-D.ietf-bmwg-virtual-net"/>)related to Benchmarks for virtual
- switches. The OPNFV project is sharing its present view on these areas,
- as they develop their specifications in the Level Test Design (LTD)
- document.</t>
-
- <section title="Comparison with Physical Network Functions">
- <t>To compare the performance of virtual designs and implementations
- with their physical counterparts, identical benchmarks are needed.
- BMWG has developed specifications for many network functions this memo
- re-uses existing benchmarks through references, and expands them
- during development of new methods. A key configuration aspect is the
- number of parallel cores required to achieve comparable performance
- with a given physical device, or whether some limit of scale was
- reached before the cores could achieve the comparable level.</t>
-
- <t>It's unlikely that the virtual switch will be the only application
- running on the SUT, so CPU utilization, Cache utilization, and Memory
- footprint should also be recorded for the virtual implementations of
- internetworking functions.</t>
- </section>
-
- <section title="Continued Emphasis on Black-Box Benchmarks">
- <t>External observations remain essential as the basis for Benchmarks.
- Internal observations with fixed specification and interpretation will
- be provided in parallel to assist the development of operations
- procedures when the technology is deployed.</t>
- </section>
-
- <section title="New Configuration Parameters">
- <t>A key consideration when conducting any sort of benchmark is trying
- to ensure the consistency and repeatability of test results. When
- benchmarking the performance of a vSwitch there are many factors that
- can affect the consistency of results, one key factor is matching the
- various hardware and software details of the SUT. This section lists
- some of the many new parameters which this project believes are
- critical to report in order to achieve repeatability.</t>

- <section title="Flow classification">
- <t>Virtual switches group packets into flows by processing and
- matching particular packet or frame header information, or by matching
- packets based on the input ports. Thus a flow can be thought of a
- sequence of packets that have the same set of header field values or
- have arrived on the same port. Performance results can vary based on
- the parameters the vSwitch uses to match for a flow. The recommended
- flow classification parameters for any vSwitch performance tests are:
- the input port, the source IP address, the destination IP address and
- the ethernet protocol type field. It is essential to increase the flow
- timeout time on a vSwitch before conducting any performance tests that
- do not measure the flow setup time. Normally the first packet of a
- particular stream will install the flow in the virtual switch which
- adds an additional latency, subsequent packets of the same flow are
- not subject to this latency if the flow is already installed on the
- vSwitch.</t>

- <section title="VSWITCHPERF Specification Summary">
- <t>The overall specification in preparation is referred to as a Level
- Test Design (LTD) document, which will contain a suite of performance
- tests. The base performance tests in the LTD are based on the
- pre-existing specifications developed by BMWG to test the performance of
- physical switches. These specifications include:</t>
-
- <t><list style="symbols">
- <t><xref target="RFC2544"/> Benchmarking Methodology for Network
- Interconnect Devices</t>
-
- <t><xref target="RFC2889"/> Benchmarking Methodology for LAN
- Switching</t>
-
- <t><xref target="RFC6201"/> Device Reset Characterization</t>
-
- <t><xref target="RFC5481"/> Packet Delay Variation Applicability
- Statement</t>
- </list></t>
-
- <t/>
-
- <t>In addition to this, the LTD also re-uses the terminology defined
- by:</t>
-
- <t><list style="symbols">
- <t><xref target="RFC2285"/> Benchmarking Terminology for LAN
- Switching Devices</t>
-
- <t><xref target="RFC5481"/> Packet Delay Variation Applicability
- Statement</t>
- </list></t>
-
- <t/>
-
- <t>Specifications to be included in future updates of the LTD
- include:<list style="symbols">
- <t><xref target="RFC3918"/> Methodology for IP Multicast
- Benchmarking</t>
-
- <t><xref target="RFC4737"/> Packet Reordering Metrics</t>
- </list></t>
-
- <t>As one might expect, the most fundamental internetworking
- characteristics of Throughput and Latency remain important when the
- switch is virtualized, and these benchmarks figure prominently in the
- specification.</t>
-
- <t>When considering characteristics important to "telco" network
- functions, we must begin to consider additional performance metrics. In
- this case, the project specifications have referenced metrics from the
- IETF IP Performance Metrics (IPPM) literature. This means that the <xref
- target="RFC2544"/> test of Latency is replaced by measurement of a
- metric derived from IPPM's <xref target="RFC2679"/>, where a set of
- statistical summaries will be provided (mean, max, min, etc.). Further
- metrics planned to be benchmarked include packet delay variation as
- defined by <xref target="RFC5481"/> , reordering, burst behaviour, DUT
- availability, DUT capacity and packet loss in long term testing at
- Throughput level, where some low-level of background loss may be present
- and characterized.</t>
-
- <t>Tests have been (or will be) designed to collect the metrics
- below:</t>
-
- <t><list style="symbols">
- <t>Throughput Tests to measure the maximum forwarding rate (in
- frames per second or fps) and bit rate (in Mbps) for a constant load
- (as defined by RFC1242) without traffic loss.</t>
-
- <t>Packet and Frame Delay Distribution Tests to measure average, min
- and max packet and frame delay for constant loads.</t>
-
- <t>Packet Delay Tests to understand latency distribution for
- different packet sizes and over an extended test run to uncover
- outliers.</t>
-
- <t>Scalability Tests to understand how the virtual switch performs
- as the number of flows, active ports, complexity of the forwarding
- logic&rsquo;s configuration&hellip; it has to deal with
- increases.</t>
-
- <t>Stream Performance Tests (TCP, UDP) to measure bulk data transfer
- performance, i.e. how fast systems can send and receive data through
- the switch.</t>
-
- <t>Control Path and Datapath Coupling Tests, to understand how
- closely coupled the datapath and the control path are as well as the
- effect of this coupling on the performance of the DUT (example:
- delay of the initial packet of a flow).</t>
-
- <t>CPU and Memory Consumption Tests to understand the virtual
- switch&rsquo;s footprint on the system, usually conducted as
- auxiliary measurements with benchmarks above. They include: CPU
- utilization, Cache utilization and Memory footprint.</t>
- </list></t>
-
- <t>Future/planned test specs include:<list style="symbols">
- <t>Request/Response Performance Tests (TCP, UDP) which measure the
- transaction rate through the switch.</t>
-
- <t>Noisy Neighbour Tests, to understand the effects of resource
- sharing on the performance of a virtual switch.</t>
- </list>The flexibility of deployment of a virtual switch within a
- network means that the BMWG IETF existing literature needs to be used to
- characterize the performance of a switch in various deployment
- scenarios. The deployment scenarios under consideration include:</t>

- <section title="Security Considerations">
- <t>Benchmarking activities as described in this memo are limited to
- technology characterization of a Device Under Test/System Under Test
- (DUT/SUT) using controlled stimuli in a laboratory environment, with
- dedicated address space and the constraints specified in the sections
- above.</t>
-
- <t>The benchmarking network topology will be an independent test setup
- and MUST NOT be connected to devices that may forward the test traffic
- into a production network, or misroute traffic to the test management
- network.</t>
-
- <t>Further, benchmarking is performed on a "black-box" basis, relying
- solely on measurements observable external to the DUT/SUT.</t>
-
- <t>Special capabilities SHOULD NOT exist in the DUT/SUT specifically for
- benchmarking purposes. Any implications for network security arising
- from the DUT/SUT SHOULD be identical in the lab and in production
- networks.</t>
