Análisis de los protocolos PTP (Precision Time Protocol) y NTP (Network Time Protocol) en redes IP utilizando equipos de conectividad del laboratorio de investigación del Departamento de Telecomunicaciones y Redes de Información

Abstract

The main object for this assignment is to analyse the protocol PTP (Precision Time Protocol) and NTP (Network Time Protocol) within the IP networks using the ALBEDO connectivity equipment. Obtained from the Telecommunications and Network information department’s investigation laboratory.

Two synchronisation test were put in place, the first one with the protocol NTP in which request messages NTP were sent from two different computers (PC1 and PC2) in different networks. In PC1 pertubations were inserted in its network path and PC2 was considered as an optimal state reference. Once the packages were received an analysis was made where explains how the perturbations affected the transmission and synchronisation. The second test was made using the Protocol PTP with a master/slave architecture in which the equipment received the reference signal by two GPS antennas.

Furthermore, Protocol MQTT, and the network equipment such as Net.Hunter, Ether.Genius, Ether.DuaLoop, Net.Storm and the rubidium atomic clock Gillam Fei was used to apply laboratory’s test, this explained how the system worked and gave a better understanding when it came to use it.
