  1. Controlling Internet Quality with Price Market Managed Multi-service Internet Bob Briscoe BTexact Research, Edge Lab, University College London & M3I Technical Director

  2. M3I • self-managing Internet resources • through market forces • show validity of approach through: • economic and network modelling • software and network engineering design & prototyping • customer experiments Controlling Internet Quality with Price

  3. price utilisation pricing principles • edge pricing & bilateral contracts - strict • (be able to) price approaching congestion • (be able to) price at service granularity - no flows, no SLAs • (be able to) introduce new tariffs& mechs- policy ctrl • (be able to) be commercially open - bundling, re-sale • minimise then synthesise • design end to end • then synthesise services at edge - technical & commercial Controlling Internet Quality with Price

  4. end to end QoS means... • QoS synthesised by the ends • scalability and evolvability • not just QoS everywhere along the path • integrated services arch (Intserv), • differentiated services SLAs (Diffserv) • ECN + diffserv field... • computing industry vs. networking industry QoS QoS QoS QoS QoS Controlling Internet Quality with Price

  6. e2e = tussle of industries • network operators & vendors think: • QoS = added value • e2e = beyond the horizon (scalability & evolvability) • solve dilemma: • design for e2e QoS • then pull back control into edge • under policy control • tariff = policy [M3I architecture] • when network-centric QoS commoditises (5-7yrs)......expose raw e2e QoS interfaces • as option e.g. for computer-computer traffic now next future Controlling Internet Quality with Price

  7. synthesised admission control dynamic congestion pricing  session admission control packet QoS  session QoS • guaranteed QoS • indistinguishable from Intserv • no per flow processing, no SLAs within ECN cloud dynamic offer dynamic offer stable offer stableoffer riskbroker riskbroker ECN cloud networkprovider networkprovider customer2 customer1 QoSgate-way QoSgate-way RSVP Controlling Internet Quality with Price

  8. no time for... • e2e QoS stability • second order dynamics of e2e QoS • user experiments on utility of stability • ECN with wireless access (no buffers) • enabling business model innovation • active tariff objects for policy control • of QoS control architecture • of charging system, rate controllers, etc. • wholesale market structure • inter-domain pricing, price-based routing • avoiding global business models (carrier selection) • retail market structure • multi-homing, provider selection by quality-value • avoiding global business models (roaming, termination charges) • SLAs irrelevant for retail market Controlling Internet Quality with Price
