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 main goal of this thesis is to investigate and analyse the Ethernet and IEEE 802.1 standards, and IPv4 and IPv6 protocols.
From those combine a new idea of Routed End-to-End Ethernet in theory and to build a Proof of Concept network that shows it in a small scale.
This concept would solve the address exhaustion problem by using MAC and NSAP addresses for host identification and for routing Ethernet packets in the network.

From Ethernet and IEEE 802.1 standards we found that the main problem of the Ethernet is that it does not have hierarchical addresses.
Hierarchical addresses would allow efficient routing enabling the network to scale globally.
IEEE 802.1 has many standards with features for scaling Ethernet networks better, but they are still not enough.
The only routing protocols used in the Ethernet networks are still the Spanning Tree Protocols.

Internet Protocol version 4 that is the dominant network protocol in the Internet, has a hierarchical address space enabling efficient routing.
A big problem with IPv4 is that the address space is small and is running out of addresses.
IPv6 has larger address space, but for some reason the deployment is really slow.

RE2EE would use Ethernet added with hierarchical addresses for the Internet.
This would make the address space large enough and also efficient routing would be possible.
In the Proof of Concept a small scale network was built, which showed that it is possible to create the basic functionalities of RE2EE using only Ethernet packets.
Abstract (fin):Tämän diplomityön tavoitteena on tutkia ja analysoida Ethernet- ja IEEE 802.1 -standardeja, sekä IPv4- ja IPv6-protokollia.
Näiden parhaita puolia yhdistämällä kehitettiin uusi päästä-päähän reitittävä Ethernet -konsepti, jonka mukaan rakennettiin Proof of Concept -verkko.
Tämä idea pyrkii ratkaisemaan Internetin suurimman ongelman, jossa osoiteavaruudesta loppuvat osoitteet, käyttämällä laitteiden identifioimiseen ja Ethernet-pakettien reitittämiseen sekä MAC- että NSAP-osoitteita.

Hierarkkisuuden puute osoitteissa estää tehokkaan reitityksen ja sen takia Ethernet-verkot eivät skaalaudu maailmanlaajuiseksi verkoksi.
IEEE 802.1 -standardeissa on parannettu Ethernet-verkkojen skaalautuvuutta, mutta osoitteistusta ei ole muutettu ja reititykseen käytetään edelleen Spanning Tree -protokollaa.

Internet-protokollan versio 4:stä tuli Internetin hallitseva verkkoprotokolla, koska siinä osoitteisto on hierarkkinen, mikä mahdollistaa tehokkaan reitityksen.
Ongelmaksi on kuitenkin muodostunut pieni osoiteavaruus, josta osoitteet alkavat loppua.
IPv6:ssa on suurempi osoiteavaruus, mutta siltikään se ei ole syrjäyttänyt IPv4-osoitteita.

RE2EE:n ideana on lisätä Ethernet-verkkoon hierarkkiset osoitteet, jotka yhdessä mahdollistaisivat riittävän ison osoiteavaruuden ja tehokkaan reitityksen.
Proof of Conceptissa luotiin RE2EE-verkko pienessä mittakaavassa ja todistettiin sen avulla RE2EE:n perusominaisuuksin toteuttaminen käyttämällä ainoastaan Ethernet-paketteja.
