IEEE 802 Standard for Computer Networks Presentation Transcript

  • 1. Need for Standardization and IEEE 802 Standard T S Pradeep Kumar Email: pradeepkumarts@gmail.com http://pradeepkumar.org
  • 2. Need for Standards • make or break networking products • Interoperability • Vendor independence is designing or manufacturing products. • Should have a common ground where manufacturer's obey the standardization
  • 3. List of Standards • There are several Standards, but most common ones are • ISO (International organization of Standardization) • IEEE (Institute of Electrical and Electronic Engineers)
  • 4. ISO • OSI Model is developed by ISO for Networking • ANSI is the member of ISO that develops standards from programming language to Disk drives
  • 5. IEEE • IEEE Society has more than 3 Lakh members • Computer Soceity of IEEE alone has more than 1 Lakh members • IEEE 802.2 - 802.5 for wired LAN Standards
  • 6. 802.1 (Bridging) • Overall picture of LAN and connectivity • addressing network management • Standards for Bridges
  • 7. 802.2 (LLC) • Logical Link Control • Communication of packets from one device to another device. • It deals with communication
  • 8. 802.3(Ethernet) • Ethernet Mainly • CSMA/CD • Speed of 10MB/s • 802.4 is Token bus and it is disbanded
  • 9. 802.5 (Token Ring) • Token Ring • Speed of 4Mbps or 16Mbps
  • 10. 802.7 .8 .9 .10 • 802.7 - Broadband LAN and it is withdrawn • 802.8 (Fiber optic cabling and access methods) • 802.9 (Voice and digital data integration) • 802.10 (interoperable security)
  • 11. 802.11 (Wi Fi) • Wireless LAN • Wi Fi Certified
  • 12. 802.11a, 802.11b • 11Mbps Data rate • PHY operates at 5GHz • Frequency of 2.400 GHz to 2.4835 GHz
  • 13. 802.11d, 802.11e • Global roaming for 802.11a and 802.11b • MAC Layer particulars set • 802.11e • Quality of Service • data, voice and video transmission prioritisation
  • 14. 802.11g, h, i • Extends the Maximum rate of 54Mbps • 802.11h • • • Transmit Power Control Dynamic Frequency Selection 802.11i • security of WLAN • key management, authentication ,etc.
  • 15. 802.11j, k, m • Japanese extension to wifi • 4.9Ghz to 5 Ghz • 802.11k • • radio resource managements 802.11m • maintenance of existing documentation
  • 16. 802.11n, 802.11ac • Multi input Multi output • Higher speed standards of up to 600Mbps • uses both 2.4GHz and lesser bands within 5GHz • 802.11ac • to be approved in Feb 2014 • addition of Multi User MIMO • 1300Mbps • 80MHz channel in 5GHz and 40MHz channel in 2.4GHz
  • 17. 802.15 (WPAN) • Wireless Personal Area Networks • 802.15.1 - Bluetooth • 802.15.3 - Short range, high bandwidth, UWB • 802.15.4 - ZigBee, Short range wireless sensor networks • 802.15.5 - Mesh Networks
  • 18. 802.1x • 802.16 - Wireless Metropolitan Area Networks (WMAN) • 802.17 - Resilient Packet Ring • 802.18 - Radio regulatory TAG for the future standards
  • 19. 802.2x • 802.20 - Wireless Mobility mobile broadband wireless access • 802.21 - Handoff/ Interoperability between networks • 802.22 - Wireless Regional Area Networks • 802.24 - Smart Grid TAG
