Colloquium rennais des sciences du numérique

3ème édition du colloquium - 4 juillet 2013

Résultat de la volonté des établissements de recherche réunis au sein du Comité de Site Math-STIC de Rennes, le Colloquium a pour but de réunir périodiquement l'ensemble des chercheurs, enseignants-chercheurs et étudiants de la place rennaise qui s'intéressent aux sciences du numérique. Depuis le 17 avril 2013, et environ tous les deux mois, un nouveau cycle de belles conférences scientifiques se tient dans l'amphithéâtre du centre Inria Rennes – Bretagne Atlantique.

Patrick Maillé & Bruno Tuffin (à 11:18 mn), An analysis of ISP Inter-Relations: Traffic Exchange, Revenue Sharing, and Disconnection Threat (durée: 33:19 mn)


Abstract
:

The network neutrality debate originally stems from the growing traffic asymmetry between ISPs, questioning the established peering or transit agreements. That tendency is due to popular content providers connected to the network through a single ISP, and whose traffic is not charged by distant ISPs. We propose during this talk to review the economic transit agreements between ISPs in order to determine their best strategy.

We define a model with two ISPs, each providing direct connectivity to a fixed proportion of the content and competing in terms of price for end users, who select their ISP based on the price per unit of available content. We analyze and compare thanks to game-theoretic tools three different situations: the case of peering between the ISPs, the case where ISPs do not share their traffic (exclusivity arrangements), and the case where they fix a transfer price per unit of volume. The impact on the network neutrality debate is then discussed.
