NEW TRENDS IN AUTONOMOUS NETWORKING - INTERNAL PROJECT
FUNDAMENTAL RESEARCH ON NOVEL

People Involved:

Communications networks are on the brim of novel revolutions. The communication paradigm that has kept the Internet going for the past 20 years is showing its limit. The addressing principle and routing are strained to the limit and IPv6 does not really seem the solution: it is a technology already old before it has been rolled out ... a bit like Asynchronous Transfer Mode in the '90s!!

At the same time cooperative networking, form P2P to Community Networks are also showing different possible paradigms of communications.

In this panorama, this fundamental research project investigated different possible solution and architectures to sustain communications and the network delivering information, starting from simple filetering techniques that can be "added" to the normal functionalities of networks to improve traffic controlo or to deliver contents based on the information itself and not based on a traditional addressing scheme, to graph analysis tools to find the best possible location for such functions, to "clean slate design" that shatters the socio-economic foundations of the Internet to guarantee that communications will survive the (inevitable) decline of the Internet as we know it today.

NAPAWINE
NETWORK-AWARE P2P-TV APPLICATION OVER WISE NETWORKS

A Small or Medium-Scale Focused Research Project of ICT Call 1 FP7-ICT-2007-1. Grant Agreement no.: 214412.

TV services over the Internet can be provided either exploiting IP multicast functionalities or relying on a pure end-to-end (P2P) approach. The first technique unfortunately, will only work on a network infrastructure controlled by a single broadband operator due to limitations of IP multicast facilities. On the contrary, the P2P approach has been successfully exploited to overcome these limits and can potentially offer a scalable planetary infrastructure. Recently, several P2P-TV systems started to show up, with the last generation offering High Quality TV (P2P-HQTV) systems, providing a ubiquitous access to the service. These same potentialities of P2P-TV systems constitute a worry for network carriers since the traffic they generate may potentially grow without control, causing a degradation of quality of service perceived by Internet users or even the network collapse (and the consequent failure of the P2P-HQTV service itself!).

Starting from these considerations the NAPA-WINE project, funded by the European Commission within the seventh framework programme, aims at:

  1. providing a careful analysis of the impact that a large deployment of both general P2P-TV and P2P-HQTV services may have on the Internet, through an in detailed characterization of the traffic they generate;
  2. providing guidelines for P2P-TV developers regarding the design of systems that minimize the impact on the underlying transport network while optimizing the user perceived quality;
  3. providing a road map for Internet Service Providers to better exploit the network bandwidth by showing simple and minimum cost actions that can be taken in presence of P2P-TV traffic.
