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):Ethernet switching is a technology which allows various computers to be connected to a local area network, passing messages / information from one to the other through the use of protocols.
Ethernet has over the years been faced with a number of problems, including bandwidth shortfalls, network loops, packet loss, security and delays.
These challenges have resulted in a number of solutions, such as STP, SPB and TRILL, and various proposals, including Ethane, Open flow and ETNA.
However, despite all these efforts, little attention has been paid to their scalability.
To address these Ethernet problems, this thesis examined the feasibility of scaling the centralized Ethernet approach.
This goal was achieved by developing a centralized Ethernet solution and analyzing the maximum number of nodes needed to provide the least amount of packet loss, delay and convergence times.
The feasibility of our solution was determined by comparing it with the existing distributed solutions.
In this study, a Boson network simulator was employed to compare the centralized and the distributed Ethernet solutions in terms of delay, convergence times and packet loss.
Although several network topologies were considered, focus was directed to three scenarios with 10, 19 and 38 operational nodes.
The results show that in terms of these parameters, the proposed centralized routing solution is best used in LANs with fewer nodes, whereas larger networks with more than 19 nodes should use a distributed approach.
