  1. Market Managed Multi-service Internet Project Overview & Architecture Bob Briscoe, BT IST Project No 11429 under the EU Vth Framework Information Society Technologies Programme

  2. aim • to self-manage Internet resources • through market forces • to show validity of approach through: • economic and network modelling • software and network engineering design & prototyping • customer experiments M3I Overview & Architecture

  3. objectives • for network customers • more effective competition between providers over price & quality • reduced congestion • instantaneously increase quality demands without asking first • real-time feedback and validation of charges • for network providers • reduced management complexity • ability to charge flexibly to encourage responsible use of available QoS or multicast • ability to change tariffs and communicate them fast • ability to hold QoS in presence of bad congestion M3I Overview & Architecture

  4. price (mgmt i/f) customer service service i/f market approach offer pricereaction pricesetting customer service load granularity important M3I Overview & Architecture

  5. network service specifics service requires >1 customer! price customer network service customer data flow service internally distributed both intra- and inter-provider networkservice competitors also peers M3I Overview & Architecture

  6. open approach • business models • not just 3 or 4 like the current ISP market • customer service selection • agent assisted • technology platforms • network • reservation signalling (RSVP), diffserv, explicit congestion notification (ECN) • systems • CORBA intra-domain allowed, but not inter-domain M3I Overview & Architecture

  8. important secondary aim • given fine-grained price control with ECN is economically and mathematically optimal… • …can it underpin a fully flexible commercial environment? • …that fits all the desires of providers and customers? • …and is it practical? M3I Overview & Architecture
