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): The purpose of this thesis is to implement a prototype for the configuration and auditing of network elements in the mobile core network.
The focus of the prototype is on the IP level.
The prototype is needed in order to evaluate the feasibility of this new type of tool.
The feedback from the prototype evaluation provides input for the full-scale implementation of the network level configuration and auditing tool.

The Waterfall model was used to steer the prototype development, because the model was considered suitable for small-scale software development projects.
The user interface of the prototype is based on the spreadsheet design, which was considered suitable for displaying network structures.
Finally, Java was chosen as the programming language because of its platform independence.

The prototype development was a success, because the prototype is capable of performing network level auditing and relatively simple configurations.
The prototype was considered as a possible choice for a network level configuration and auditing tool.
In addition, it was thought that the full-scale version of the tool could simplify and speed up network management tasks.

From a technical perspective, no problems were found during the prototype development that would prevent the full-scale implementation of the tool.
This thesis provides some suggestions for the full-scale development.
For example, it is recommended to analyze whether the user interface of the tool should be renewed.
Abstract (fin): Tämän työn tarkoituksena on toteuttaa prototyyppi, jolla voi hallita ja valvoa runkoverkon verkkoelementtejä IP-tasolla.
Prototyyppiä tarvitaan uudentyyppisen ohjelmiston soveltuvuuden arviointiin, josta saatua tietoa voidaan myöhemmin hyödyntää kokoversion toteutuksen yhteydessä.

Prototyyppi kehitettiin vesiputousmallin avulla, joka todettiin sopivaksi pienimuotoisen ohjelmiston kehitykseen.
Prototyyppi perustuu taulukkolaskentaohjelmista tuttuun käyttöliittymään, jonka arvioitiin sopivan hyvin verkon struktuurin kuvaamiseen.
Ohjelmointikieleksi valittiin Java, koska sen avulla voitiin taata alustariippumattomuus.

Prototyypin kehitys onnistui hyvin, sillä prototyypillä on mahdollista auditoida verkkoja sekä tehdä suhteellisen yksinkertaisia konfigurointeja.
Prototyyppi todettiin yhdeksi vaihtoehdoksi toteuttaa työkalu verkkotason hallinnointiin ja valvontaan.
Lisäksi työkalun kokoversiolla arvioitiin olevan mahdollista yksinkertaistaa ja nopeuttaa verkkojen hallintaa.

Työkalun kehityksen aikana ei löydetty teknisiä esteitä sen jatkokehitykselle.
Kokoversion toteutuksen yhteydessä kannattaa hyödyntää tässä työssä esitettyjä suosituksia.
On esimerkiksi suositeltavaa tutkia, pitääkö työkalun käyttöliittymään tehdä muutoksia.
