Method and node for distributed network performance monitoring

Abstract:

A method and a node for distributed performance monitoring in a communication network comprising a set of nodes. Each node in the set is configured to operate alternatively as a monitor node or as a sensor node and wherein each monitor node in the network is configured to perform measurements together with a corresponding sensor node. The monitor node determines (from a priority list) the sensor node which has the highest priority and sends a first query to that sensor node. The sensor node on its side has a listening period for receiving queries. When the listening period expires, the sensor node selects the monitor node having the highest query priority and performs measurements together with said selected monitor node.
