Semester 1 v3.1.1Networking Basics

• MODULE 7
• Ethernet Technologies

2
IEEE 802.3 Old School Ethernet

• Legacy Ethernet comprises
• 10BASE5 over Thicknet co-ax copper
• 10BASE2 over Thinnet co-ax copper
• 10BASE-T over CAT3/4/5 UTP copper
• 10BASE-FP/FB/FL over optic fibre
• Shares same frame format, timing parameters,
  transmission process, Manchester encoding scheme.

3
IEEE 802.3u Ethernet hits 100

• 100BASE-T4 over CAT3 UTP copper
• 100BASE-T2 over CAT3 UTP copper
• 100BASE-TX over CAT5 UTP copper
• 100BASE-FX over multimode optic fibre
• Shares same frame format as 10Mbps Ethernet.
• Uses 4B/5B encoding, scrambled and converted to
  MLT-3 line encoding.

4
IEEE 802.3z Gigabit Power

• 1000BASE-SX short wavelength over optic fibre
• 1000BASE-LX long wavelength over optic fibre
• 1000BASE-CX over balanced copper
• Shares frame format with earlier Ethernet
  varieties.
• Bit times may vary with implementation
• Full-duplex communications, as IEEE 802.3z MAC
  treats links as point-to-point.
• 8B/10B encoding converted to Non-Return to Zero
  (NRZ) line encoding.

5
IEEE 802.3ab Gigabit over UTP

• 1000BASE-T over CAT5e UTP
• Shares frame format with earlier Ethernet
  varieties.
• Uses 4D-PAM5 line encoding.
• Layer 1 Forward Error Correction (FEC) and
  dynamic voltage levels help achieve 1Gbps.

6
IEEE 802.3ae 10GigEth

• 10000BASE-SR over multimode optic fibre
• 10000BASE-LX4 WDM over optic fibre
• 10000BASE-LR/ER over single mode optic fibre
• 10000BASE-SW/LW/EW over OC-192 STM SONET/SDH
• Shares frame format with earlier Ethernet
  varieties.
• Full-duplex communications, CSMA/CD rules
  ignored.
• OSI Layers 1 2, plus interoperability with
  SONET.

7
Ethernet Developments

• IEEE 802.3 LANs and MANs
• IEEE 802.3ak 10000BASE-CX4 WDM over balanced
  copper
• IEEE 802.3an 10000BASE-T over CAT5e UTP
• IEEE 802.3aq 10000BASE-LRM over FDDI-grade
  multimode optic fibre
• IEEE 802.11 Wireless LANs
• IEEE 802.11n high throughput in 2.4GHz spectrum
• IEEE 802.11p wireless in vehicular environments
• IEEE 802.15 Wireless PANs
• IEEE 802.15.1 Bluetooth v1.1 specs
• IEEE 802.16 Broadband Wireless MANs operating
  below 11GHz spectrum.
