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):Data consumption is increasing rapidly in mobile networks.
The cost of network infrastructure is increasing, which leads to an "end of profit" within next few years.
Thus, mobile operators require a new technology that allows increasing the network capacity within low network costs.
Therefore, using caching is the most evident solution to be used in their backhaul networks.
However, the current architecture of LTE network does not provide sufficient flexibility to place the caches in the most optimal locations.
The current work on Software-Defined Networking in Evolved Packet Core virtualization has enabled us to integrate a dynamic caching functionality in a LTE network and improve the caching system performance.
In this thesis, we present the solution we designed for this aim based on Software-Defined Networking technology.
Moreover, we developed a testbed for the proof-of-concept and we present the results and analyze the performances of this solution.
We propose three possible optimizations, that we analyze through a simulation.
