A threshold-based caching mechanism for distributed network monitoring tools

A critical issue in monitoring and controlling geo-distributed dual-stack networks may be the following one:
if a Remote Component has to send all the gathered traffic to the Central Component, the information is doubled with a consequent significant waist of bandwidth. This is particularly true if the gathered information is repeated and redundant. In this case, the information might be preprocessed on the Remote Component to obtain and propagate to the Central Component only the essential part of information useful for the network management.
In a distributed statistical-based monitoring tool (i.e. that uses statistics to synthesize the whole information gathered, extracting only the essential pieces of information), the goal of minimizing the exchanged traffic, can be achieved by using a caching mechanism and by processing the gathered information on the Remote Components using simple and efficient algorithms to reduce the flow of information, before sending it to the Central Component.This report describes how to address the latter issue on a Remote Component,
introducing a threshold-based caching mechanism for minimizing the transmission of the gathered information to the Central Component and proving its efficiency by showing results obtained by taking some measurements on a real network. This mechanism has been implemented and is used to minimize information exchange in the distributed components of 6MoN.
