  1. Dynamic Traffic Management (DTM) for minimization of inter-domain traffic cost • Rafal Stankiewicz, Zbigniew Dulinski • AGH University of Science and Technology • Department of Telecommunications • RACI BoF session

  2. AGH University of Science and Technology Department of Telecommunications Krakow, Poland Socially-aware Management of New Overlay Application Traffic with Energy Efficiency in the Internet European Seventh Framework Project FP7-2012-ICT- 317846

  3. Background peers peers peers Cloud provider DC A DCC DCB • Manage the traffic: • Selection of content source (multiple resources available, communicate with overlay application, e.g. by using ALTO) • Select the path, e.g. by using tunnels (might be transparent to or cooperate with overlay) • The content is not available locally • The download will generate inevitable inter-domain traffic • The cost of the downstream traffic depend on the tariff on inter-domain link used • Optimize total cost of inter-domain traffic peers ISP-3 ISP-1 ISP-2 Transit network end-user DC ISP-0 Content requestors

  4. Traffic management Total amount of traffic in each periodnremains the same, but the traffic is differently distributed among two links TARGET traffic (cost) to be achieved in the current period TARGET traffic (cost) to be achieved in the current period n–1 n n+1 n+2 n+3 n+4 n–1 n n+1 n+2 n+3 n+4 manageable traffic non-manageable traffic 5 min samples 5 min samples Link 2 Link 1

  5. Basic assumptions • Tariffs based on total traffic volume or 95th percentile • Upstream and downstream traffic management • Find cost-optimal traffic distribution on inter-domain links • Goal – minimize cost by the end of accounting period – long time scale • Influence traffic distribution dynamically on short time scale • Observe traffic on links • Periodic measurements and estimation of final cost • Influence the manageable traffic by selecting path for flows

  6. Sample use-case DC DC Cloud A • Cloud agnostic • Tunnels (GRE or MPLS) between DAs (Data Center Access router) located in different ISP domains • Simple management in DAs • Recognize flows • Choose appropriate interface (tunnel) for the flow • SDN controller • Agreements between ISPs may be needed ISP-C ISP-A Cloud A DC ISP-B DA-A DA-B ISP-D

  7. DTM – traffic management concept Optimization algorithm Compensation algorithm Metering component

  8. DTM – traffic management concept Finds optimal goal vector Dt Optimization algorithm Calculates compensation vector Ut e.g. every 5 min and influences path selection Compensation algorithm Metering component Monitors current traffic on inter-domain links and calculated measured vector Xt e.g. every 30s e.g. (modified) NetFlow

  9. Simulation results – 95th percentile tariff Cumulated traffic volume on links Without compensation With compensation Goal vector of traffic [GB] Time [h] [GB] Time [h]
