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.

RTP
Abstract (eng): In the current Internet, most transport protocols select a single path for communication flow between two end hosts, even when multiple paths exist.
Such flows are unable to fully utilize the available resources.
Multipath capability refers to the simultaneous use of multiple paths through the network, which may significantly improve performance and reliability.
This area is of particular interest in real-time communication where it would improve the end-user experience by enhancing the quality of service.
Firstly, bandwidth-hungry applications such as video streaming and IP-TV can benefit from the increased, combined throughput available to multihomed clients.
Also, as retransmission of lost data is often uncharacteristic of real-time traffic because of time constraints, multipath senders can avoid lossy paths or send redundant data over multiple paths.
Furthermore, session-based real-time communication can benefit from the redundancy by implementing fail over in case of network failures.

In this thesis, we present Multipath RTP as an extension to RTP with multipath capability.
We propose a MPRTP scheduling algorithm for sending RTP packets over multiple paths in the form of a basic MPRTP implementation.
Finally, we evaluate its performance in a virtual test environment consisting of a two multihomed clients with three paths available between them.
