Terminology for Frame Relay Benchmarking
Alternative Format: Original Text Document
RFC 3133 Terminology for Frame Relay Benchmarking June 2001
For the purposes of computing several of the metrics, certain textual
conventions are required. Specifically:
1) The notation sum {i=1 to N} A_i denotes: the summation of N
instances of the observable A. For example, the set of observations
{1,2,3,4,5} would yield the result 15.
2) The notation max {I=1 to N} A_i and min {I=1 to N} A_i denotes:
the maximum or minimum of the observable A over N instances. For
example, given the set of observations {1,2,3,4,5}, max {i=1 to 5} =
5 and min {I=1 to 5} = 1.
The terms defined in this memo will be used in addition to terms
defined in RFCs 1242, 1944 and 2285. This memo is a product of the
Benchmarking Methodology Working Group (BMWG) of the Internet
Engineering Task Force(IETF).
2. Existing Definitions
RFC 1242, "Benchmarking Terminology for Network Interconnect
Devices", should be consulted before attempting to make use of this
document. RFC 1944, "Benchmarking Methodology for Network
Interconnect Devices", contains discussions of a number of terms
relevant to the benchmarking of switching devices and should also be
consulted. RFC 2285, "Benchmarking Terminology for LAN Switching
Devices", contains a number of terms pertaining to traffic
distributions and datagram interarrival. 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.
