Benchmarking Methodology (bmwg) --------------------------------------------------- Current Status: Active Working Group r4 Last Updated 2010-10-20 Chair: Al Morton <acmorton@att.com> Operations and Management Area Directors: Ronald Bonica <rbonica@juniper.net> Dan Romascanu <dromasca@avaya.com> Operations and Management Area Advisor: Ronald Bonica <rbonica@juniper.net> Mailing Lists: Address: bmwg@ietf.org To Subscribe: bmwg-request@ietf.org Archive: http://www.ietf.org/mail-archive/web/bmwg/ Description of Working Group: 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. Each recommendation will describe the class of equipment, 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 terminology 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 description of the task, as listed below. 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 discussion regarding the advancement of measurements designed to provide insight on the capabilities and operation of inter-networking technology implementations. The BMWG will communicate with the operations community through organizations such as NANOG, RIPE, and APRICOT. In addition to its current work plan, the BMWG is explicitly tasked to develop benchmarks and methodologies for the following technologies: * 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. * Flow Export and Collection: Develop terminology and methods to characterize network devices flow monitoring, export, and collection. The goal is a methodology to assess the maximum IP flow rate that a network device can sustain without losing any IP flow information or compromising the accuracy of information exported on the IP flows, and to asses the forwarding plane performance (if the forwarding function is present) in the presence of Flow Monitoring. * Data Center Bridging Devices: Some key concepts from BMWG's past work are not meaningful when testing switches that implement new IEEE specifications in the area of data center bridging. For example, throughput as defined in RFC 1242 cannot be measured when testing devices that implement three new IEEE specifications: priority-based flow control (802.1Qbb); priority groups (802.1Qaz); and congestion notification (802.1Qau). Since devices that implement these new congestion-management specifications should never drop frames, and since the metric of throughput distinguishes between non-zero and zero drop rates, no throughput measurement is possible using the existing methodology. The current emphasis is on the Priority Flow Control aspects of Data Center Bridging, and the work will include an investigation into whether TRILL RBridges require any specific treatment in the methodology. This work will update RFC 2455 and exchange periodic Liaisons with IEEE 802.1 DCB Task Group, especially at WG Last Call. * Content Aware Devices: New classes of network devices that operate above the IP layer of the network stack require a new methodology to perform adequate benchmarking. Existing BMWG RFCs (RFC2647 and RFC3511) provides useful measurement and performance statistics, though they may not reflect the actual performance of the device when deployed in production networks. Operating within the limitations of the charter, namely blackbox characterization in laboratory environments, the BMWG will develop a methodology that more closely relates the performance of these devices to performance in an operational setting. In order to confirm or identify key performance characteristics, BMWG will solicit input from operations groups such as NANOG, RIP and APRICOT. * LDP Dataplane Convergence: In order to identify key LDP convergence performance characteristics, BMWG will solicit input from operations groups such as NANOG, RIP and APRICOT. When relevant performance characteristics have been identified, BMWG will jointly prepare a Benchmarking Terminology Document with the Routing Area (e.g., the MPLS working group and or the RTG-DIR), which would define metrics relevant to LDP convergence. The Benchmark definition document would be Last-Called in all the working groups that produced it, and solicit operator input during the last call. The work will then continue in BMWG to define the test methodology, with input and review from the aforementioned parties.
