FTTX-Analysverktyg anpassat för Telias nät / FTTX-Analysis tool designed for Telia's networkBrännback, Andreas January 2018 (has links)
Ett verktyg har utvecklats i programmeringsspråket Python, som analyserar status för uppkopplingar hos Fibre to the X (FTTX)-kunder i Telias nät. Systemet består av en moduluppdelad struktur, där alla analysfunktioner av samhörande typer är uppbyggda i egna moduler. Alla moduler lagras som individuella kodfiler. Systemet är designat för att enkelt kunna vidareutvecklas genom att tillägga fler analysmoduler i framtida projekt. För att utföra en analys på en specifik kund, hämtar systemet tekniska dataparametrar via den switch som kunden sitter uppkopplad mot. Dessa parametrar jämförs därefter med förbestämda värden för att hitta avvikelser. Simple network management protocol (SNMP) och Telnet är de primära protokollen som används för att hämta relevant data. Systemet har enbart Hypertext Transfer Protocol (HTTP) som input och output. Resultatet av en analys, redovisas som Extensible Markup Language (XML) mot den server som ursprungligen ställde förfrågan till att starta en analys. XML svaret innehåller både tekniska dataparametrar kring kundens uppkoppling samt ett analyssvar baserat på dessa tekniska parametrar. Utförligheten i svaret på en utförd analys varierar en aning beroende på switchtypen kunden sitter uppkopplad mot. Switchar av äldre hårdvarutyper presenterar generellt sett mindre kundportsdata jämfört med modernare varianter. Mindre kundportsdata leder till sämre utförlighet i analyssvaret. Därför lämpar sig detta analysverktyg bättre mot de modernare switcharna som finns i Telias nät. / A tool for analyzing the status of Fiber to the X (FTTX) customers in Telia’s network has been programmed in the Python programming language. The system consists of a module divided structure where analysis functions of similar types are bundled into module files. The system is designed to be easily further developed by adding more analysis modules in future projects. To perform an analysis on a specific customer, the system retrieves technical data parameters from the switch which the customer is connected to, and compares these parameters against predetermined values to find deviations. Simple Network Management Protocol (SNMP) and Telnet are the primary protocols used to retrieve data. Hypertext Transfer Protocol (HTTP) is used to transfer data as system input and output. The result of an analysis is sent as Extensible Markup Language (XML) back to the server that originally requested the start of an analysis. The XML reply contains technical data parameters describing the customer’s connection status and an analytical response based on these technical parameters. The amount of data presented in the XML response varies slightly depending on the type of switch the customer is connected to. Switches of older hardware types generally presents less customer port data compared to more modern switches. Less customer port data leads to poor detail in the analytical response, and therefore, this analysis tool is better suited to the modern switches found in Telia's network.

Návrh optické přístupové sítě FTTx / Design of FTTx optical access networkMünster, Petr January 2010 (has links)
The aim of this work is an overview of the proposal for FTTx Optical Access Networks. In the introductory chapter written about the optical fiber and the transmission. Furthermore, as already discussed various options with regard to the implementation instead of the end of optical fiber - FTTN, FTTC, FTTP, FTTB, FTTH and standards, which are used to build fiber optic networks. The next chapter is an overview of the network elements that are in different layers reference model ISO / OSI used. The final theoretical chapter is devoted to progressive technologies for the construction of optical access networks, which has recently been used. Concepts are explained as HDPE pipe, microtubing or self-supporting cables. The practical part design model, passive optical networks in the area Slavičín, located in the Zlín region. FTTB architecture was chosen, where for each connection object is used in the existing copper lines. The proposed route will use a standard technology GEPON Wavelength division WDM, so to connect the individual buildings will be used only one thread. Realization of optical networking technology will be excavation. The optical cables and optical fiber bundles are protected by HDPE pipes stored in the bed of sand. For the optical signal split into multiple lines will be used by an optical splitter 1 / 16, located in an outdoor cabinet optic pathway. The distribution of signals for the settlement will take care Alloptic central station, which is optimized for the transmission of Triple Play services. On the basis of the proposal is to created a financial analysis that shows the return on the project. An important part of the network is also monitoring the network. The last part of this work therefore deals with the possibilities of monitoring networks in order to continuously monitor the network, in order to prevent any disturbances or quickly respond to network problems.

Model metropolitní optické sítě / Model of the metropolitan optical networkPrudík, Jiří January 2008 (has links)
The purpose of this master’s thesis is foremost to provide a simple guide how to build elements of optical metropolitan area network. The basic model consists to sequence of construction, network topology, passive and active parts. The collection contains examples of alternative technology such as Wireless LAN with different frequency. The optical network construction based on optical cable, fibres, splices, trays, adapters, connectors and active parts for example a lot of media convertor models. After that there are demonstrating type of wavelength division multiplexer used in metropolitan area network – passive planar PCL splitter. One of the passive planar splitter are used to increase optical fibre channel. At the end of the collection a simplified examples of used measurements – optical time domain reflectometry and optical fibre transmission. Contains standard protocols or reflectogram. The conclusion of this thesis summarizes costs of FTTb (Fibre To The Building) model of optical metropolitan area network in Czech republic and future contribution for society.
