The ability to measure our networks is critical for long and short term planning needs. This lecture discusses several general-purpose tools to investigate different aspects of the network.
By the end of this lesson, the student will be able to:
describe the purposes of network measurement, both from a short-term and longer-term perspective.
describe the uses of basic measurement tools (packet traces, SNMP counters, ping, traceroute).
describe the use of netflow tools and how they differ from other measurement tools. Be able to solve problems requiring knowledge of the flow definition, flow record, sampling methods and flow aggregation.
analyze a scenario to pick the most appropriate measurement tool.
