Considerations in Benchmarking Routing Protocol Network Convergence

This draft discusses various aspects of measuring routing protocol network convergence and explores techniques and tools used for these measurements, aiming to form a consensus on their meanings. It provides an overview of the network under test and the impact of measurement tools on convergence times. The draft also addresses considerations in polling devices and common convergence measurement techniques.

  1. Considerations in Benchmarking Routing Protocol Network Convergence R White, M Vishwas, R Adams

  2. What it’s Not • A comprehensive list of possible ways to test routing protocols convergence in a network. • A definition of how routing protocols convergence should be tested in a network.

  3. What it is • A draft which considers various aspects of measuring routing protocols convergence in a network. • Something to start us thinking about the techniques and tools used to perform these measurements, and to form a concensus around the meanings of those measurements. • Consider what we would like to measure.

  4. Overview of the Draft • What is the network under test? • There is the network, and there are the tools being used to generate the network events through which convergence times are measured. • The tools can impact the measured convergence times as much as the network does, especially a convergence times reduce into the noise level of the tools.

  5. Overview of the Draft • What is convergence? • What, exactly, are we trying to measure? • Some techniques separate the control plane from the forwarding plane, others don’t. • Considerations in Polling Devices

  6. Overview of the Draft • Considerations on common convergence measurement techniques. • Black Box Polling • White Box Output • External Packet Monitoring

  7. To Do • Should this be here or in IPPM? • If here, should it be a WG doc? • On the doc itself, several pieces are missing: • Testing is under way in several quarters to compare emulated networks to real networks; this testing could result in a new doc, or could be added to this one. • The discussion of testing methods could probably be filled in more.
