Terminology for ATM ABR Benchmarking

RFC 3134          Terminology for ATM ABR Benchmarking         June 2001


   the ability to configure ATM addresses (via hard coded addresses,
   ILMI or PNNI neighbor discovery), has the ability to run SSCOP, and
   has the ability to perform signaled call setups (via UNI or PNNI
   signaling).  Finally, this document presents only the terminology
   associated with benchmarking IP performance over ATM; therefore, it
   does not represent a total compilation of ATM test terminology.

   The BMWG produces two major classes of documents: Benchmarking
   Terminology documents and Benchmarking Methodology documents.  The
   Terminology documents present the benchmarks and other related terms.
   The Methodology documents define the procedures required to collect
   the benchmarks cited in the corresponding Terminology documents.

2. Existing Definitions.

   RFC 1242, "Benchmarking Terminology for Network Interconnect
   Devices", should be consulted before attempting to make use of this
   document.  RFC 2544, "Benchmarking Methodology for Network
   Interconnect Devices", contains discussions of a number of terms
   relevant to the benchmarking of switching devices and should be
   consulted.  RFC 2285, "Benchmarking Terminology for LAN Switching
   Devices", contains a number of terms pertaining to traffic
   distributions and datagram interarrival.  RFC 2761, "Terminology for
   ATM Benchmarking", contains a number terms pertaining to traffic
   management [TM4.0, TM4.1].  Many of the metrics defined in RFC 2761
   (e.g., CDV, CER, CLR, CMR, and CTD) also apply to ABR performance
   benchmarking.  These metrics will not be redefined in this document.
   For the sake of clarity and continuity, this RFC adopts the template
   for definitions set out in Section 2 of RFC 1242.

II. Definitions

   The definitions presented in this section have been divided into two
   groups.  The first group is formal definitions, which are required in
   the definitions of the performance metrics but are not themselves
   strictly metrics.  These definitions are subsumed from other work
   done in other working groups both inside and outside the IETF.  They
   are provided as a courtesy to the reader.
