Introduction to Telecommunication

evolution of the internet
Evolution of the Internet

Question posed in 1963 by RAND, a cold war think tank.

“How could the U.S. communicate after a nuclear attack?”

internet evolution
Internet Evolution


The communication network would require:

  • The intelligence to reside in the endpoints
  • Any endpoint could talk to any other endpoint
  • Network Routing be self-healing after attack
  • No centralized control
  • Messages divided into packets that could take any number of paths from source to destination
internet evolution4
Internet Evolution
  • Internet began as ARPANET in the late 1960s, run by Dept. of Defense
  • Development of TCP/IP Protocols in mid 1970s, incorporated into ARPANET in 1983
  • NSF supports TCP/IP in CSNET in early 1980s
  • ARPANET and CSNET merge in 1980s
internet evolution5
Internet Evolution
  • NSF subsidizes NSFNET backbone and regional networks in 1986
  • NSF Phases out federal support for Internet backbone in 1992-95
  • Internet commercialized in mid 1990s
the world wide web
The World Wide Web
  • Created by Tim Berners-Lee in 1991 at the European Center for Nuclear Research (CERN)
  • Portion of the Internet that utilizes a software program (browser) to display WebPages
  • Browser development: Mosaic in 1993; Netscape Navigator popularized in mid 90s
internet in context
Internet in Context
  • Internet is convergence
  • Unique Multi-modal capabilities and user-driven qualities compared to previous telecommunication technologies
  • Many predict shared protocol of the Internet is platform of the future
brief overview of the internet
Brief overview of the Internet
  • Digital data and bits (1’s & O’s) are packet switched on interconnected networks through use of routers and communication links
  • Packet-switching involves TCP/IP
brief overview of the internet9
Brief overview of the Internet
  • Best efforts routing; packets of related-information (e.g. email) may travel different paths
  • Packets reassembled at final destination
  • e2e allows for creative applications and software
  • Openness key to daisy chaining, e2e & more
who governs the internet
Who governs the Internet?
  • No centralized controlling authority
  • Standards and protocols set by a number of self-governing organizations, including:
    • Internet Society (ISOC)
    • Internet Architecture Board (IAB)
    • Internet Engineering Task Forces (IETF)
    • Internet Corporation for Assigned Names and Numbers (ICANN)
  • Existing governing and political institutions may influence policy
  • Misnomer to believe Internet is completely unregulated
internet is convergence
Internet is convergence
  • Common product/service platform that support multiple functions
  • Driven by digitization, bandwidth and throughput
  • Form of information carried traditionally by different delivery mechanisms: voice (telephone), data (private corporate network), and video (broadcast network or cable tv)
  • Multi-modal content
why broadband throughput matters transfer rate of a 10 megabyte file 10 20 minute video clip
Why Broadband Throughput Matters: Transfer Rate of a 10-Megabyte File (10-20 minute video clip)
  • Telephone modems, 28.8 Kbps – 46 minutes, 56.6 Kbps – 24 minutes
  • ISDN modem, 128 Kbps – 10 minutes
  • Typical Cable & ADSL, 1.54 Mbps – 52 seconds
  • 4-Mbps – 20 seconds
  • 10-Mbps – 8 seconds
from narrowband to broadband
From Narrowband to Broadband
  • Definition of Broadband Internet
    • Internet access with a minimum capacity of greater or equal to 256 kbit/s in one or both directions (ITU)
    • 200 kbit/s in or both directions (FCC)
  • Fixed Broadband: DSL, Cable Modem, FTTH
  • Mobile Broadband: W-CDMA, CDMA 2000
  • Portable Internet: WLAN, WMAN, WiMAX
from narrowband to broadband14
From Narrowband to Broadband
  • In the U.S. Cable Modem is dominant technology for fixed broadband services (44.1 %).
  • High-speed lines by technology as of June 30th, 2006

  • Benefits of Broadband Deployment
  • Approximately 50 million households in the U.S. (45 percent) subscribe to a broadband connection (high speed Internet access)
      • Currently more than 4 Million Voice-over Internet Protocol (VoIP) residential telephone subscribers in U.S.
      • 50 Million Internet Telephony (Skype) Users
      • Total High-speed lines in the U.S. (1999-2006)
fixed broadband deployment
Fixed Broadband Deployment
  • US Ranks only 15th among 30 OECD countries in terms of fixed broadband penetration rate.
mobile broadband deployment
Mobile Broadband Deployment
  • US Ranks only 24th among ITU membership countries in terms of mobile broadband penetration rate.
  • Mobile Broadband Penetration Rate: 1.46 per 100 inhabitants (ITU, 2005).
