  2. Overview • More precise measurement procedures • Complete list and description of foreground and background traffic characteristics • Scalable test configurations • Reporting requirements

  3. Latency Measurement • Precise procedure description • Includes mean and standard deviations • Various intensities of foreground traffic (0+%, 50%, 75%, 87.5%, ...) • Various intensities of background traffic (0%, 50%, 75%, ... of max background load)

  4. Foreground Characteristics • Type of VCCs: PVP, SVP, PVC, SVC, • VCCs between ports on same/different modules/fabrics. “Same module” may or may not be better. • Service class: UBR, ABR • Arrival patterns: equally spaced frames, self-similar, random • Frame length: 64 B, 1518 B, 9188 B or 64 kB, variable; • Full foreground load (FFL) • Input rate/FFL = 0+, 0.5, 0.75, ... 1-2-k, k = 1, 2, ...

  5. Background Characteristics • Type of VCCs: PVP, SVP, PVC, SVC, • VCCs between ports on same/differentmodules/fabrics • Connection configuration: n-to-n straight, n-to-(n-1) full cross, n-to-m partial cross with m = 2, 3, 4, ...,n-1 • Service class: UBR, ABR, CBR, and VBR • Arrival patterns: equally spaced frames, self-similar, random • Frame length: 64 B, 1518 B, 9188 B or 64 kB, variable • Maximum background load (MBL) =  Link Rates • Input rate/MBL = 0, 0.5, 0.75, 0.875,... 1-2-k, k = 0, 1, 2, ...

  7. Motion • Adopt the text of 97-0611 to replace section 3.2 of Performance Testing Baseline Text.
