10 Gigabit Ethernet: Customer Applications

IEEE 802.3ae Interim May 2000 Bruce Tolley Cisco Systems First Principles

• Buildings will not move because of 10 GbE • Customers have a requirement to run new network gear on the existing installed infrastructure • Customers are smart

IEEE 802.3ae Why 10 Gigabit Ethernet

• 75% of new LAN clients are 100 Mbps (Intel, zdnet.com) • Industry shipping over 250 thousand GbE ports/month • Leverages installed base of 250 million Ethernet switch ports

IEEE 802.3ae Task Force Goals & Customer Requirements •MAC – Support Ethernet installed based while scaling Ethernet speed • Maintain 802.3 frame format and size. •PMD – Support distances from 100 m on installed MMF to 40 km on SMF •PHY – LAN PHY: support transmission of data on dark fiber and dark wavelength while maintaining traditional simplicity of Ethernet – WAN PHY adds support for transmission of Ethernet on installed base of SONET/SDH transport infrastructure
