INTERNET-DRAFT Terminology for Accelerated Stress Benchmarking  October 2003

   1. Introduction

   Routers in an operational network are simultaneously configured with
   multiple protocols and security policies while forwarding traffic and
   being managed.  To accurately benchmark a router for deployment it is
   necessary to test that router in operational conditions by
   simultaneously configuring and scaling network protocols and security
   policies, forwarding traffic, and managing the device.  It is helpful
   to accelerate these network operational conditions so that the
   router under test can be benchmarked with faster test duration.
   Testing a router in accelerated network conditions is known as
   Accelerated Stress Testing.

   This document defines the Benchmark Planes used for the Accelerated
   Life Benchmarking.  These are the Control Plane, Data Plane,
   Management Plane, and Security Plane.  For each plane, the
   Configuration Set, Startup Conditions, and Instability Conditions.
   Terms are also defined for observing Failure Conditions and reporting
   Benchmarks.  White Box benchmarks are provided in Appendix 1 for
   additional DUT behavior measurements.

   2.  Existing definitions

   RFC 1242 "Benchmarking Terminology for Network Interconnect
   Devices" and RFC 2285 "Benchmarking Terminology for LAN Switching
   Devices" should be consulted before attempting to make use of this
   document.

   For the sake of clarity and continuity this RFC adopts the template
   for definitions set out in Section 2 of RFC 1242.  Definitions are
   indexed and grouped together in sections for ease of reference.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in
   this document are to be interpreted as described in RFC 2119.


3. Term definitions

   3.1 Benchmark Planes

      Definition:
        The features, conditions, and behavior for the Accelerated Stress
        Benchmarking.

      Discussion:
        There are four Benchmark Planes: Control Plane, Data Plane,
Management Plane, and Security Plane as shown in Figure 1. The
        Benchmark Planes define the Configuration, Startup Conditions,
        Instability Conditions, and Failure Conditions used for the test.

   3.5 Failure Conditions

   3.5.1 Unexpected Session Loss

      Definition:
        Session Loss due to Control Plane or Data Plane failure during the
        Accelerated Stress Benchmarking.

      Discussion:
        Session loss will be observed due to Convergence Events produced
        by the Instability Conditions.  This is not considered a failure
        during the Accelerated Stress Benchmarking. It is expected behavior.
        Unexpected packet loss occurs due to Data Plane or Control Plane
        failure.

      Measurement units:
        sessions

      Issues:
        None

      See Also:
        Unexpected Packet Loss
        Misrouted Packets

   3.5.2 Unexpected Packet Loss
      Definition:
        Packet Loss due to Control Plane or Data Plane failure during the
        Accelerated Stress Benchmarking.

      Discussion:
        Packet loss will be observed due to Convergence Events produced
        by the Instability Conditions.  This is not considered a failure
        during the Accelerated Stress Benchmarking. It is expected behavior.
        Unexpected packet loss occurs due to Data Plane or Control Plane
        failure.

INTERNET-DRAFT Terminology for Accelerated Stress Benchmarking  October 2003

   3.5.3 Misrouted Packets

      Definition:
        Packets routed to the incorrect next-hop or LSP due to Control
        Plane failure during the Accelerated Stress Benchmarking.

      Discussion:
        Packets will be rerouted to new next-hops and LSPs due to Convergence
        Events produced by the Instability Conditions.  This is not considered
        a failure during the Accelerated Stress Benchmarking. It is expected
        behavior.  Unexpected Misrouted packets occur due to Control Plane
        failure.

      Measurement units:
        packets

      Issues:
        None

      See Also:
        Unexpected Packet Loss
        Unexpected Session Loss
        Access Denial
        Errored Management Values
        Security Plane Failure

   3.5.4 Access Denial

      Definition:
        Inability to management the DUT due to the inability
        to gain remote access to the DUT.

      Discussion:
        Handling of Instability Conditions may cause a Control Plane failure
        of the DUT externally observable as the inability to remotely manage
        the DUT.  Whether using SNMP, Telnet, SSH, or FTP, failure to manage
        the device constitues a failure.

      Measurement units:
        Failed session

      Issues:
        None

      See Also:
        Unexpected Packet Loss

INTERNET-DRAFT Terminology for Accelerated Stress Benchmarking  October 2003

   3.5.5 Errored Management Value

      Definition:
        Incorrect SNMP object value or statistic during the Accelerated
        Life Benchmark.

      Discussion:
        Management of a router relies upon accurate reporting of object
        values and statistics.  The Accelerated Stress Benchmarkinging validates
        that the DUT is able to report correct values when experiencing
        Instability Conditions.

      Measurement units:
        Name of incorrect object or statistic

      Issues:
        None

      See Also:
        Unexpected Packet Loss
        Unexpected Session Loss
        Misrouted Packets
        Access Denial
        Security Plane Failure
        Success Threshold

   3.5.6 Security Plane Failure
      Definition:
        Violation of Security Policy for packets directed to the DUT
        or routed through the DUT.

      Discussion:
        Security Policy is configured to permit and deny access to packets
        destined for the DUT and packets to be routed through the DUT.
        A violation of this security policy is when either a packet to
        be denied is permitted or a packet to be permitted is denied.

      Measurement units:
        packets

      Issues:
        None

      See Also:
        Unexpected Packet Loss
        Unexpected Session Loss

   3.6 Benchmarks

   3.6.1 Success Threshold

     Definition:
        The intended number of hours for the DUT to operate without failure
        during the Accelerated Stress Benchmarking.

      Discussion:
        Success Threshold is a user determined value of time.  It is
        necessary to define the Success Threshold because it is possible
        for the DUT to experience zero failures for given Configuration
        Sets, Startup Conditions, and Instability Conditions

      Measurement units:
        Hours

      Issues:
        None

      See Also:
        Accelerated-Life Test Duration


   3.6.2 Accelerated-Life Test Duration

      Definition:
        The run-time for the Accelerated Stress Test without the DUT
        exhibiting an error in the control plane, data plane, management
        plane, or security plane.

      Discussion:
        For a successful test, the Test Duration will equal the
        Success Threshold.  In the event of any failure, the Test Duration
        is less than the Success Threshold.  Reporting of the Test
        Duration MUST inlcude the Failure Condition from those defined
        in this document.

      Measurement units:
        Hours

      Issues:
        None

   4. Security Considerations
        Documents of this type do not directly effect the security of
        the Internet or of corporate networks as long as benchmarking
        is not performed on devices or systems connected to operating
        networks.
