Abstract
This article presents a design of a database model used to gather and analyze data frames transmitted over gigabit passive optical network (GPON) in the downstream direction. An issue with this kind of system is the difficulty in analyzing a transmission on the optical part which is caused by the difference among devices using Ethernet frames technology and passive optical network technology with usage gigabit encapsulation method. In this article, a principle of the downstream direction is described. Next, the design of the database model for the analysis of transmitted data is discussed. Based on the design and implementation of the database, a script capable of processing data gathered by a programmable network card is proposed. The script for physical layer operation, admission, and maintenance (PLOAM) messages analysis is written in the Python programming language.
Highlights
With an increasing number of Internet users, the number of services which are capable of gathering, sharing, and processing information increase as well [1,2]
The main idea of a passive optical network is to transmit the signal without further amplification, so that the network is composed only of the basic elements such as optical line terminal (OLT), splitters, optical network unit (ONU) and optical network terminate (ONT), etc., see Figure 1
These two units terminate the optical network on the user side, the ONU is positioned at an optical distribution point, and the signal is further propagated from that point by other technologies, for example by digital subscriber line, or by wireless fidelity (Wi-Fi), etc
Summary
With an increasing number of Internet users, the number of services which are capable of gathering, sharing, and processing information increase as well [1,2]. As the requirements on speed and data availability are increasing, the demands for high-quality and reliable Internet connections are growing [3,4]. This growing applies to corporate customers or other organizations and to households or individual end-users. Given this trend, it is clear that there has been a considerable increase in the transmission of information and the standard copper wire links are being replaced by high-speed optical links in the backbone and access networks.
