It DNS ccTLD and a large 3G mobile network with million of users. This work has been successfully validated on using this architecture for monitoring the. This paper describes how the microcloud architecture can be used to provide real-time traffic monitoring and correlation on large distributed environments where monitoring traffic is analyzed by several probes that collectively concur to the monitoring task. This task adds extra load on collectors and prevents traffic information to be available until it has been correlated, thus preventing (near) realtime traffic monitoring.

merging data coming from all the probes and correlate information. As each probe monitors a part of the traffic, the data collector has the responsibility of. Each probe analyzes the traffic and sends the monitoring data toward a centralized management station often using protocols such as NetFlow and IPFIX. Monitoring of large distributed networks requires the deployment of several probes at different network locations where traffic to be analyzed is flowing. Our experiments show that introducing the packet size parameter in the probe gap model formula improves considerably the accuracy of the measurements. Then, we investigate the quantitative relationship of IGMPS measurement accuracy to several probing parameters such as the packet size and the number of probing packet pairs. Based on an experimental analysis in various network testbed configurations, we present IGMPS measurement results that verify the tool behavior and illustrate its accuracy. Based on this deterministic model and considering a particular case obtained when the two packets of the probing pairs are of the same size, we develop an active measurement tool called IGMPS (Improved Gap Model using Packet Size parameter ) that estimates the end-to-end available bandwidth at the bottleneck link of the path.

taking into account the size of each probing pair packet. Installation First of all, you have to install the ntopng plugin (os-ntopng) from the plugins view reachable via System Firmware Plugins.

This model captures the relationship between the amount of cross traffic and the packet pair gap. In this paper, we develop a new deterministic model of packet pair delays for end-to-end available bandwidth estimation in IP network paths. The packet pair technique is one of the most popular of them. To measure available bandwidth, many different active probing techniques have been developed.
