T-110.557 Research seminar on telecommunications software (2-4 cr) Fall 2004

Seminar topic fall 2004: Identifier/Locator split and DHTs

In the current IP architecture, an IP address acts both as a locator (a name of a topological location of a host) and as an identifier (a name of a host, independent of its location). The increasing need to support mobile and multi-homed hosts, or multi-addressed hosts for short, demand that these two roles of IP addresses are separated from each other. At the IETF, there are a number of proposals (for example, HIP) on how to introduce such a separation into the current architecture without breaking too much.

In this research seminar, we will study the proposed ID/locator split, and the underlying phenomena. Additionally, we will study Distributed Hash Tables (DHTs), and study how they can be used to solve the so called referral problem in the new architectures.



The lecture time will be 16:00 - 17:30, Wednesday, without any breaks. The first lecture will start on Wed Sep 15.

Requirements and participations

The seminar will have two different requirements, one set for undergraduate students and the other one for graduate students. The undergraduate students would just read two papers and give 15 min presentations about the central ideas on the papers. While the graduate students would work on their own related work, writing a paper, and then giving a talk at a NetSec like full day seminar.

Passing requirements for undergrads (2 cr):

  1. 2 seminar presentations, 15 min each
  2. 70% participation to the weekly meetings
  3. participation to the full day meeting
  4. The students should send the slides for their presentations to the address t-110.557@tml.hut.fi at latest on the Friday before their presentation.

Passing requirements for grad students (4 cr):

  1. 60% participation to the weekly meetings
  2. brief e-mail write ups of the papers of the weekly meetings missed, sent to the assistants
  3. writing the paper, 8-12 pages
  4. presenting the paper at the full day meeting
