7 Standard “Paragraph” (intro/security) Benchmarking activities as described in this memo are limited to technology characterization using controlled stimuli in a laboratory environment, with dedicated address space and the constraints specified in the sections above. 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. Further, benchmarking is performed on a "black-box" basis, relying solely on measurements observable external to the DUT/SUT. 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.

10 Charter Text Extension In addition to its current work plan, the BMWG is explicitly tasked to develop benchmarks and methodologies for the following technologies: * MPLS Forwarding: Develop specific methods to characterize the latency and forwarding performance of MPLS devices, extending the fundamental recommendations of RFC 1242 and RFC 2544 to this networking technology. * 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.
