  1. 1. Simple Economic Management Approaches of Overlay Traffic in Heterogeneous Internet Topologies European Seventh Framework STREP FP7-2007-ICT-216259 Information Flows in an Economic Aware Context UZH, DoCoMo, TUD, AUEB, PrimeTel, AGH, ICOM, UniWue, TID Session on Novel Networking andIoanna Papafili, Relationship with Applications –Network Economics and Services Lab The Value of Information FlowsAthens University of Economics and Business between Application and Networks FIA Aalborg, May 10, 2012
  2. 2. The SmoothIT project - Economic Traffic Management (ETM)• Context: SmoothIT focused on overlay application and p2p – Addressed the Information Asymmetry problem• Concept: ETM employs mechanisms addressing the incentives of players – They are compatible to users’ benefit, but also function complementarily to the self-organization of the overlay• Objective: To bridge the information gap between overlay and underlay and to optimize overlay traffic mutually beneficially for all: ISP, user, ASP  – TripleWin: the system operates in an equilibrium point – Traditional traffic optimization would aim at a global optimum of a single combined optimization metric• Results: ETM mechanisms indeed lead the system to desirable equilibria, although a different mechanism can be appropriate in each case – Are highly distributed and scalable – Stimulate information sharing among players• Next steps: Handle new types of overlay traffic stemming from – Social networks, cloud applications, mobile applications7/2/2012 2
  3. 3. The SmoothIT Information Service (SIS) AS 65504 SIS P9 AS 65510 AS 65508 SIS AS 65509 P8 IP/MPLS transit P7 SIS SIS P4 P5 P6 New P3 P2 P1 Candidates: P1,P2,…,P9 Peer SIS: SmoothIT Information Service Sorted List: P1,P2,P3,P7,…• Each SIS component can convey information between overlay and underlay• E.g. overlay components interact with SIS to select “better” peers• The application client can ignore SIS recommendations if not beneficial!7/2/2012 3
  4. 4. SIS-compatible/-enabled ETM mechanisms• BGP-based Locality Promotion – Neighbors list provided by peer requesting ‘advice’ – A server provides proximity-related information/’advice’• Insertion of ISP-owned Peer(s) – Intervention of resourceful caches in the overlay, transparently or not – Tranparent: Selected by regular peers only based on overlay criterion (e.g. T4T) – Non-transparent: Advertised by SIS (or possibly the overlay tracker)• Promotion of Highly Active Peer(s) – ISP boosts regular high activity peers’ capacity – Evaluates their behavior, e.g. large seeding time – Incentive for regular peers to act as IoPs• All provide freedom to peers to decide whether they will adopt them7/2/2012 4
