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): This master's thesis studies the distribution of IPTV channels from a core network to the edges of a MetroEthernet network.
The goal is to find a faster solution for configuring multicast trees using protocols implemented by vendors.
The current solution which uses Resource reSerVation Protocol for signalling MultiProtocol Label Switched tunnels, Internet Group Management Protocol Snooping for mapping receivers and Protocol Independent Multicast-Source Specific Multicast for core multicast creates too much work.

The new solutions combine RSVP, point-to-multipoint RSVP, Fast ReRoute and PIM-SSM and they are tested in the TeliaSonera networking laboratory.

Based on test results there is not much certainty about many things but it can be said that FRR seems to be working well and it is easy to use.
Furthermore, P2MP RSVP seemed promising for the core network with faster convergence times in failure cases than PIM-SSM.
However, there are few problems to be solved before the protocol is ready for use in the production network.
Abstract (fin): Diplomityössä tutustuttiin IPTV-kanavien siirtoon Core-verkosta MetroEthernet-verkon asiakasta lähinnä olevalle laidalle.
Tavoitteena oli kehittää nopeampi ratkaisu monilähetyspuiden konfigurointiin laitevalmistajan toteuttamilla protokollilla.
Nykyinen ratkaisu, jossa käytetään Resource reSerVation Protocol:ia MultiProtocol Label Switching-tunneleiden signaloimiseen, Internet Group Management Protocol Snooping:ia halukkaiden vastaanottajien kartoittamiseen sekä Protocol Independent Multicast-Source Specific Multicast:ia runkoverkon monilähetykseen on liian työläs.

Uudet ratkaisut, joissa yhdistellään RSVP:tä, point-to-multipoint RSVP:tä, Fast ReRoutea ja PIM-SSM:ia testataan TeliaSoneran tietoverkkolaboratoriossa.

Tulosten perusteella ei voida sanoa paljoa varmasti, mutta FRR ME-verkossa vaikuttaa helppokäyttöiseltä ja toimivalta ratkaisulta.
Lisäksi P2MP RSVP-TE herätti toiveita nopeammin vikatilanteista toipuvasta monilähetysratkaisusta runkoverkosta, kunhan ilmenneiden vikojen syyt saadaan selville.
