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 summarizes the progress of the Open Platform for NFV - (OPNFV) project on virtual switch performance characterization, - "VSWITCHPERF", through the Brahmaputra (second) release <xref - target="BrahRel"/>. 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 often - 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. The authors are - currently doing their best to maintain alignment with many other - projects, and this Internet Draft is one part of the efforts. We - acknowledge the early work in <xref - target="I-D.huang-bmwg-virtual-network-performance"/>, and useful - discussion with the authors.</t> - </section> - - <section title="Scope"> - <t>The primary purpose and scope of the memo is to inform the industry - of work-in-progress that builds on the body of extensive BMWG literature - and experience, and describe the extensions needed for benchmarking - virtual switches. Inital feedback indicates that many of these - extensions may be applicable beyond the current scope (to hardware - switches in the NFV Infrastructure and to virtual routers, for example). - Additionally, this memo serves as a vehicle to include more detail and - commentary from BMWG and other Open Source 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.

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> - - <section title="Benchmarks using Baselines with Resource Isolation"> - <t>This outline describes measurement of baseline with isolated - resources at a high level, which is the intended approach at this - time.</t> - - <t><list style="numbers"> - <t>Baselines: <list style="symbols"> - <t>Optional: Benchmark platform forwarding capability without - a vswitch or VNF for at least 72 hours (serves as a means of - platform validation and a means to obtain the base performance - for the platform in terms of its maximum forwarding rate and - latency). <figure> - <preamble>Benchmark platform forwarding - capability</preamble> - - <artwork align="right"><![CDATA[ __ - +--------------------------------------------------+ | - | +------------------------------------------+ | | - | | | | | - | | Simple Forwarding App | | Host - | | | | | - | +------------------------------------------+ | | - | | NIC | | | - +---+------------------------------------------+---+ __| - ^ : - | | - : v - +--------------------------------------------------+ - | | - | traffic generator | - | | - +--------------------------------------------------+]]></artwork> - - <postamble/> - </figure></t> - - <t>Benchmark VNF forwarding capability with direct - connectivity (vSwitch bypass, e.g., SR/IOV) for at least 72 - hours (serves as a means of VNF validation and a means to - obtain the base performance for the VNF in terms of its - maximum forwarding rate and latency).

The purpose of soak tests is to capture transient - changes in performance which may occur due to infrequent processes - or the low probability coincidence of two or more processes. The - performance must be evaluated periodically during continuous - testing, and this results in use of <xref target="RFC2889"/> Frame - Rate metrics instead of <xref target="RFC2544"/> Throughput (which - requires stopping traffic to allow time for all traffic to exit - internal queues).</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> - - <t>Tests derived from examination of ETSI NFV Draft GS IFA003 - requirements <xref target="IFA003"/> on characterization of - acceleration technologies applied to vswitches.</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.
