Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): With the emergence of new broadband telecommunication services and constantly increasing bandwidth demand, fixed access network infrastructure is evolving from electrical to optical.
The European Commission funded research project Scalable Advanced Ring-based passive Dense Access Network Architecture (SARDANA) researches the next-generation passive optical access network technologies.
The main goal of the project is to reduce expenses that are related to passive optical access networks.

This master's thesis discusses the design of the non-standardized 10 Gigabit-capable Passive Optical Network (XGPON) Transmission Convergence (TC) layer and its first implementation version for Optical Network Unit (ONU) for the SARDANA test network.
The SARDANA XGPON TC (SXGTC) layer implements the Medium Access Control (MAC) protocol.
The SXGTC layer is based on the standardized solution offered by the ITU-T G.984.3 Gigabit-capable Passive Optical Network (GPON) TC (GTC) layer recommendation [ITU08] but differs from it in many details.
All the SXGTC layer features are compared to those of the GTC layer.

As a result, the SXGTC protocol is able to support operation on up to 9.95328 Gbps symmetrical transmission rates.
The SXGTC layer is optimized for the 8-byte-word-based data processing.
The first ONU SXGTC layer Field Programmable Gate Array (FPGA) implementation is presented in terms of functional blocks.
The implementation supports operation on 9.95328 Gbps in the downstream offering 98 % bandwidth efficiency and on 2.48832 Gbps in the upstream offering 94.5 % bandwidth efficiency for the SARDANA test network configuration.
Abstract (fin): Uusien laajakaistaisten tietoliikennepalvelujen ja kasvavan tiedonsiirtokapasiteetin tarpeen myötä kiinteiden liityntäverkkojen infrastruktuuri on muuttumassa sähköisestä optiseksi.
Euroopan komission rahoittamassa Scalable Advanced Ring-based passive Dense Access Network Architecture (SARDANA)-tutkimusprojektissa tutkitaan seuraavan sukupolven passiivisten optisten liityntäverkojen teknologioita.
Projektin päätavoitteena on pienentää passiivisiin optisiin liityntäverkkoihin liittyviä kustannuksia.

Tämä diplomityö käsittelee SARDANA-testiverkon standardoimattoman 10 Gigabit-capable Passive Optical Network (XGPON) Transmission Convergence (TC)-kerroksen suunnittelua ja ensimmäistä toteutusta optisessa verkkopäätteessä (ONU:ssa).
TC-kerros toteuttaa Medium Access Control (MAC)-protokollan.
SARDANA XGPON TC (SXGTC)-kerros perustuu standardoituun ITU-T G.984.3 Gigabit-capable Passive Optical Network (GPON) TC (GTC)-kerroksen [ITU08] tarjoamaan ratkaisuun mutta eroaa tästä yksityiskohdiltaan.
Kaikki SXGTC-kerroksen oleelliset yksityiskohdat peilataan GTC-kerrokseen.

Suunniteltu SXGTC-protokolla tukee maksimissaan 9.95328 Gbps:n symmetrisiä tiedonsiirtonopeuksia.
SXGTC-protokolla on optimoitu käsittelemään dataa 8 tavun sanoissa.
Ensimmäinen ONU SXGTC-kerroksen toteutus ohjelmoitavassa Field Programmable Gate Array (FPGA)-piirissä esitellään funktionaalisten lohkojen avulla.
Tämän implementaation tiedonsiirtonopeus alasuunnassa on 9.95328 Gbps 98 %:n kaistatehokkuudella ja yläsuunnassa 2.48832 Gbps 94.5 %:n kaistatehokkuudella SARDANA-testiverkkokonfiguraation tapauksessa.
