Project proposals

Background

Information-centric networking (ICN) address data by name contrary to Internet Protocol host-centric paradigm. As a result, data in information-centric networking is not strictly associated to an end-host IP address, but can be retrieved by hop-wise replication and in-network caching instead of end-to-end IP stream. In IOT perspective, this provide an ability to relax the demand for continued connectivity, and thus this is mention as a potential alternative solution for networking for the IOT. ICN is oriented around publish-subscribe, and hence information is pulled by requesting data of interest. Two data packets are used. INTEREST request data, while DATA is sent in respond to the INTEREST and hold the requested content.

Problem

General assumption for ICN is bidirectional links, that is, traffic is transmitted in both direction over a link. This general assumption is not always true in dynamic wireless networks, and thus neither true in the IOT operating over wireless links. In wireless environments, link quality can vary both over a long timeframe, as well, as over a shorter timeframe. The link error will also typically differentiate over the direction of the link.

Master assignment

The master candidate should build an IOT network, and further evaluate the network using NDN for acquiring data of interest. The candidate should further identify the problem of asymmetric links, and eventually propose a solution to mitigate the identified problem(s).

Video conferencing over ICN

Background

Distributing and manipulating named information is a major application in the Internet today. In addition to web-based content distribution, video and especially videoconferencing are examples of popular services. Today a central server is responsible of connecting the participants running a videoconference. The cost of running this central server is not negligtable due to hardware, software, management of the server and providing sufficient network resources. Typically, the central server establish an end-to-end TCP/UDP stream to each participant, and further send equal content on each data stream.

Information-centric networking (ICN) address data by name contrary to Internet Protocol host-centric paradigm. As a result, data in information-centric networking is not strictly associated to an end-host IP address, but the data is retrieved by hop-wise replication and in-network caching instead of end-to-end IP stream. The architecture is therefore potential more suitable for videoconferencing than by today use of IP.

Problem

Uninett facilitates tele and video conferences over IP using one or more central servers. These servers are costly and, hence Uninett is interested in exploring whether Uninett get any benefit from using videoconferencing based on ICN solution(s) instead of IP. The benefit of ICN is reduced requirement of a central server facilitating the service.

Master assignment

The master assignment is divided in two parts; technical and economical. The first and main part is technical and consist of build a testbed based on NDN, and further evaluating NDN videoconference utilizing Uninett as backbone. The second part is economical. That is, the candidate should discuss eventual benefit, requirements of shifting from IP to NDN videoconferencing and the associated cost.
