Economic and User Perspective of Inter-ISP Traffic Optimization

  1. 1. Socio-Economic Services forSocio-European Research Projects (SESERV)European Seventh Framework CSA FP7-2010-ICT-258138 FP7- 2010- ICT- Economic and User Perspective of Inter-ISP Traffic Optimization UZH, IT Innovation, AUEB, UOX, ALBLF, AOSAE FI Cluster Meeting Brussels, BelgiumBurkhard Stiller, UZH February 11, 2011 © 2010 The SESERV Consortium 1 Traffic Management and Optimization Traffic Management – The task of mapping traffic flows onto an existing physical topology. The key goals – Minimization of packet loss and packet delay – Optimization of network resources (avoiding overload situations through load balancing) Traffic engineering “applications” allow for a precise control of how traffic flows are placed within a routing domain or between those (ASes: Autonomous Systems) Traffic optimizations alternatives – Use of proximity information (BGPLoc) – Application of caching techniques (IoP/IoS) – Promotion of Highly Active Peers (HAP) © 2010 The SESERV Consortium 2

Traffic Map (Example)© 2010 The SESERV Consortium 3 Stakeholders‘ ClassificationNetwork Service Providers – Internet Service Providers (ISP) – Telecommunication Service Providers (Telco) Provider-providerApplication Service Providers Relations – Content – Service – Overlay – ... User-provider RelationsUser and customer – Individual, residential Multiple, diverging – SME, residential/commercial interests! – Corporate, commercial© 2010 The SESERV Consortium 4
  3. 3. Socio-economic Tussle Space (Samples)ISP – ISP (technology view): (expensive) traffic management needs • Per user, per session, per stream, per flow, per unit of interest – ISP (commercial view): optimizing revenues • Flat rate versus resource-based pricing Diverging optimizationUser dimensions! – QoS/QoE: local perception only • E.g., video traffic, social network messages, distributed games – Variety of rates, tariffs, and prices Preference levelsApplication providers of prices vs. quality – Delivery of quality applications – Economically viable ratio between effort and revenue© 2010 The SESERV Consortium 5 ConclusionsUser-to-user communications are a must – buttechnology choices vary a lot – P2P, e2e, cleint-to-client, ... users‘ choice, no ISP involvedUsers don‘t care about Inter-ISP issues ... as long as perceived quality fits demands – Need to be (at least) transparent for the userISPs care about costs related to inter-ISP traffic – Peerings vs. Contracts – Need for non-costly traffic optimizationsWhere are the incentives for ISPs and users?© 2010 The SESERV Consortium 6
