Abstract:

A monitoring system gathers both site-to-site measurements, and agent-to-agent measurements, wherein one or more agents are distributed in one or more sites in a distributed network environment. Site-to-site measurements between two sites, such as site one and site two, are obtained by testing between any agent at site one and any agent at site two. A measurement rate between sites and between agents is determined that allows for the detection of events, such as user perceivable events, without overwhelming the set of agents that form the distributed measurement system. With, for example, a scheduling mechanism used to schedule measurement tests of finite duration, as opposed to continuous streams of measurement packets, for each pair of agents, the test can be used as an indication as to whether the measurement system is overwhelmed.
