A. Moore’s Law
Gordon E. Moore. "Cramming more components onto integrated circuits," Electronics, volume 38, number 8 (19 April, 1965), at http://www.intel.com/research/silicon/moorespaper.pdf
• Exponential increase in the number of components on a chip • Doubling of number of transistors on a chip every 18 months (1980s) • Doubling of microprocessor power every 18 months (1990s) • Computing power at fixed cost is doubling every 18 months (1990s)
Throughput of integrated circuits, in MIPS, will doubled every 18 months with cost of decrease by 50%, and this regularity will remain correct for several decades. (MIPS -millions of instructions per second)
• Reliability• Power consumption • Miniaturization (number of transistors per chip) • Terminal devices in the single chips

B. Photonic technologies
Fiber optic cables for long-haul networks – beginning of 70-th
Main directions of FOC development:
• The transition from multimode to single mode fiber
• Wavelength changing of the applied spectral windows with =0,85 mkm to =1,33/1,55 mkm
• The decrease of attenuation in the fiber from figures of several dozens of dB/km to 0,2 dB/km
8
Photonic technologies (Cntd)
# Main requirements – grows of network capacity
# Boom growth of traffic, especially data
# Number of factors:• Accelerated development of the Internet• Commercial applications of graphic and video information exchange • The growth of worldwide business, which leads to the growth of worldwide traffic
# New technologies for photonic networks

A. Digitalization
Digitalization of:
• Information
• Information processing tools
• Transportation systems
Transition from analog to digital format
• Analog networks - separate
• Integrated networks - digital
• Convergence in ICT

Brief History of the Internet•1957– Launch of Sputnik is impetus for U.S. to form ARPA (DoD)•1965 – ARPA sponsors a study “Cooperative network for time-sharing”; Innovation of packet switching (D. Devis, UK, P. Baran, US)• 1969 – September 2, launch of first computer network ARPANET • 1972 – Beginning of E-mail (Tomlinson, US)• 1974 – First article about TCP/IP (Cerf/Kahn)•1979 – Establishing first research computer network (NSF, Univ. Wisc., DARPA)
C. Internet
20
Brief History of the Internet (Cntd) •1982 – Internet defined as TCP/IP-connected network•1986 – 56 kb/s NSFNET created for 5 supercomputing centers• 1989 – Number of Internet nodes breaks 100 000; IETF comes into existence• 1992 – WWW released; Number of nodes breaks 1M• 1995 – VoIP comes to the market
• 2001 – Number of hosts breaks 300M
• 2002 – VoIP has taken away 13% of long-haul telephone traffic

Internet market maturity(TeleGeography Survey, 2005)
Stabilization of traffic•Global cross-border internet traffic will grow by 49% in 2005, down from 103% in 2004•In the mid-2005 – 1 Tbit/s•In 2008 - 2-3 Tbit/s
Stabilization of prices•In 2004, backbone access prices around the world fell about 50 percent over the previous year•In 2005 prices fell between 23 and 33 percent, and many providers have stated that they have no plans to reduce prices further
26
Some issues of Internet traffic
• Most traffic is from corporations (80% estimated)– Main growth is from corporations
– “Last mile” has been improving rapidly (100–1000 Mbps)
– Corporate traffic is anti-recessionary
• Move from public networks to private networks using Internet for cost reduction (VPN)
27
- Corporate Internet use hit critical mass in 2000
•Now need to use the Internet for all business
•Inter-corporate traffic is now mainly over the Internet
•Intra-corporate traffic is growing in size (E-mail documents)
- Personal traffic is growing but broadband deployment is slow
- Internationally, traffic is still at the pre-2000 growth rate of 2.8/year
