The telecommunications industry at a crossroads:Uncertain economics overpowermazy technological innovation Master in Engineering Policy and Management of Technology Instituto Superior Tecnico, Lisbon, Portugal P. Ferreira February 1st, 2002
Agenda FEDERAL FIRMS MARKET Telecommunications Act ARPANET NSF Backbone optics 1 3 CHALLENGES 70 80 2 90 00 10 4 TCP/IP WWW Local Loop Private ownership
The Early Days 1 • The cold war times: the ARPANET (’69) • BBN (AS#1) (70s) and packet switching • TCP/IP (’74) and the OSI model (80’s) • The NSF backbone (early 90s)
Technology & Innovation 2 • The World Wide Web (‘89) and browsers (’93) • Classless Inter-domain Routing (’91/’92) • Border Gateway Protocol (’94/’95) • Peering: Bill&Keep, Complex routing policies 23000 20000 6800 35000 30000 400000 30000 2300000 80000 Source: Matrix Internet and Directory Services (MIDS)
Private Business 3 • The industry (infra-structure): • Quest: fiber deployment • Cisco: the routing oligopoly • AT&T: telephony and data businesses • Akamai: web-site mirroring and caching • Services and e-business: • Amazon: sales front-end • eBay: general item auction • Vehix: automotive “vortal” • BandX: bandwidth trading
Private Business 3 • Telecommunications Act of 1996 • The current backbone: • Optical Networks and cross-connects (e.g. cost model) • Wavelength division multiplexing • Peering agreements and interconnection • The access loop: • Unbundling and competition • Digital subscriber line and cable modems (e.g. cost models) • Wireless technologies
Future Challenges 4 • Pricing models: • Flat rate, Usage rate, Congestion rate • Quality of service: IntServ, DiffServ, CBR • Bandwidth trading: • Extreme competition with SLAs • Moore’s law, direct linking, GigaPOPs
Conclusions(with an EP perspective) competition Overpowered by Uncertain economics policy unbundling 90s Mazy innovation economics 80s 00s technology backbone local loop
