  1. 10-Gigabitni Ethernet Studij FER-2 Studijski program Računarstvo VI semestar Modul Telekomunikacije i informatika Predmet Lokalne mreže (preporučeni izborni predmet modula) doc. dr. sc. Željko Ilić

  2. 10-Gigabit Ethernet – 10GbE • standard IEEE 802.3ae-2002 • IEEE 802.3ae Task Force: • podršku joj pruža 10GEA (10 Gigabit Ethernet Alliance) • prijenosna brzina 10 Gbit/s • cijena samo 2-3 puta veća od GE • podržava • IEEE 802.3 standarde nižih brzina • upravljanje prometnim tokovima (IEEE 802.3x) • samo dvosmjerni prijenos • mediji: SMF, MMF i UTP (paralelno sučelje) • definiran kao LAN i WAN sučelje (OC-192c) • primjena u LAN-u, MAN-u, SAN-u i WAN-u 10-Gigabitni Ethernet

  3. Protokolna arhitektura IEEE 802.3ae • MDI – Medium Dependant Interface • XGMII – 10 Gigabit Media Independent Interface • PCS – Physical Coding Sublayer • PMA – Physical Medium Attachment • PMD – Physical Medium Dependent • WIS – WAN Interface Sublayer 10-Gigabitni Ethernet

Podsloj 10 GE LAN PHY 10 GE WAN PHY LAN i WAN PHY serijsko sučelje 4-struko serijsko sučelje serijsko sučelje MAC 10 Gbit/s 10 Gbit/s 10 Gbit/s PCS 64B66B 8B10B 64B66B SONET uokvirenje PMA XSBI XAUI XSBI PMD 1550 nm DFB 1310 nm FP 850 nm VCSEL 1310 WWDM 1550 nm DFB 1310 nm FP 850 nm VCSEL linijska brzina 10,3125 Gbaud 43,125 Gbaud 9,95328 Gbaud • vrste lasera: DFB – Distributed Feedback, FP – Fabry-Perot, VCSEL – Vertical Cavity Surface Emitting Laser 10-Gigabitni Ethernet

  5. PMD – 10GBASE-xy • slovo x • S – short wavelength, • L – long wavelength, • E – extra long wavelength; • slovo y • R – LAN PHY koji koristi kodiranje 64B66B, • W – LAN PHY koji koristi enkapsulaciju 64B66B podataka u okvire OC-192c/STM-64 (VC-4-64c); • 10GBASE-LX4 – WWDM PMD • L – long wavelength, X - kodiranje 8B10B, 4 – broj valnih duljina koje se šalju; • 10GBASE-CX4 – IEEE 802.3ak 10-Gigabitni Ethernet

  6. Pregled svih 10GbE standarda • 10GBASE-T (802.3an) • segment se sastoji od UTP kabela kategorije 6 sa 4 parice, svaka se parica koristi za dvosmjerni prijenos • maksimalnaduljina segmenta 100 m • 10GBASE-LRM – LR po MMF • maksimalna duljina segmenta 220 m 10-Gigabitni Ethernet
