10 gigabit ethernet technology

  2. 2. 10 GIGABIT ETHERNET TECHNOLOGY INTRODUCTION <ul><li>Ethernet essential for internet. </li></ul><ul><li>10 Gigabit Ethernet is the latest. </li></ul><ul><li>It finds its applications in LAN, MAN, WAN and SAN. </li></ul><ul><li>Provides high speed and reliable network . </li></ul><ul><li>Provides low installation and maintenance cost . </li></ul>Presented By: Ramotar Prasad Sahoo
  3. 3. 10 GIGABIT ETHERNET TECHNOLOGY HISTORY <ul><li>Developed by Robert Metcalfe and David Boggs in 1973 at Xerox PARC. </li></ul><ul><li>In June 2002 IEEE adopted 10 Gigabit Ethernet Standard(802.3ae). </li></ul>
  4. 4. 10 GIGABIT ETHERNET TECHNOLOGY 10 GbE TECHNOLOGY OVERVIEW <ul><li>Retention of 802.3 MAC and frame format </li></ul><ul><ul><li>64 – 1518 Byte frames </li></ul></ul><ul><ul><li>Jumbo-frames not included in standard </li></ul></ul><ul><li>No half duplex mode </li></ul><ul><ul><li>different from other versions of Ethernet </li></ul></ul><ul><li>No CSMA/CD on full duplex </li></ul><ul><ul><li>Simultaneous sending and receiving at all times </li></ul></ul><ul><li>Works with 802.1Q, 802.3ad, etc. </li></ul><ul><li>Fiber interfaces only – no copper versions </li></ul><ul><li>LAN PHY – 10Gb/s </li></ul><ul><li>WAN PHY – 9.29Gb/s (SONET framing overhead) </li></ul>
  5. 5. 10 GIGABIT ETHERNET TECHNOLOGY 10 GbE STANDARD <ul><li>Under the International Standards Organization’s Open Systems Interconnection (OSI) model, Ethernet is fundamentally a Layer 2 protocol. </li></ul><ul><li>IEEE 802.3ae was adapted to include 10 - Gbps full-duplex transmission over fiber - optic cable. </li></ul><ul><li>10 Gigabit Ethernet uses the IEEE 802.3 Ethernet Media Access Control (MAC) protocol, the IEEE 802.3 Ethernet frame format, and the minimum and maximum IEEE 802.3 frame size. </li></ul><ul><li>10 Gigabit Ethernet remains true to the original Ethernet model. </li></ul>
  6. 6. 10 GIGABIT ETHERNET TECHNOLOGY 10 GbE ARCHITECTURES <ul><li>10 Gigabit Ethernet uses two separate encoding steps. </li></ul><ul><li>The encoded data provides synchronization, efficient usage of bandwidth, and improved signal - to - noise ratio characteristics. </li></ul><ul><li>All 10GbE varieties use optical fiber media. </li></ul>

  8. 8. 10 GIGABIT ETHERNET TECHNOLOGY GIGABIT vs 10-GIGABIT ETHERNET Gigabit Ethernet 10-Gigabit Ethernet CSMA/CD + full duplex Full duplex only Leveraged Fibre Channel PMDs New optical PMDs Reused 8B/10B coding New coding schemes 64B/66B Optical/copper media Optical media only (copper in development) Support LAN to 5 km Support LAN to 40 km
  9. 9. 10 GIGABIT ETHERNET TECHNOLOGY CHIP INTERFACE(XAUI) <ul><li>The XAUI is designed as an interface extender, and the interface, which it extends, is the XGMII, the 10 Gigabit Media Independent Interface.The XGMII is a 74 signal wide interface (32-bit data paths for each of transmit and receive) that may be used to attach the Ethernet MAC to its PHY. </li></ul><ul><li>Benefits of XAUI technology - low EMI due to it's self-clocked nature, compensation for multi-bit bus skew -- allowing significantly longer-distance chip-to-chip -- error detection and fault isolation capabilities, low power consumption, and the ability to integrate the XAUI I/O within commonly available CMOS processes. </li></ul>
  10. 10. 10 GIGABIT ETHERNET TECHNOLOGY PHYSICAL MEDIA DEPENDENTS(PMDs) <ul><li>The IEEE 802.3ae Task Force has developed a draft standard that provides a physical layer that supports link distances for fiber optic media as shown in Table A. To meet these distance objectives, four PMDs were selected. </li></ul>
  11. 11. 10 GIGABIT ETHERNET TECHNOLOGY PHYSICAL LAYER(PHYs) <ul><li>The LAN PHY and the WAN PHY will operate over common PMDs and, therefore, will support the same distances. . </li></ul><ul><li>The 10 Gigabit LAN PHY is intended to support existing Gigabit Ethernet applications at ten times the bandwidth with the most cost-effective solution. </li></ul><ul><li>The 10 Gigabit Ethernet WAN PHY supports connections to existing and future installations of SONET/SDH (Synchronous Optical Network/Synchronous Digital Hierarchy) circuit-switched telephony access equipment. </li></ul>
  12. 12. 10 GIGABIT ETHERNET TECHNOLOGY APPLICATIONS FOR 10 GbE 10 Gigabit Ethernet in Local Area Networks <ul><li>Ethernet technology is already the most deployed technology for high performance LAN environments. </li></ul><ul><li>With the extension of 10 Gigabit Ethernet into the family of Ethernet technologies, the LAN now can reach farther and support up coming bandwidth hungry applications. </li></ul><ul><li>With 10 Gigabit backbones installed, companies will have the capability to begin Gigabit Ethernet service to workstations and, eventually, to the desktop in order to support applications such as streaming video, medical imaging, centralized applications, and high-end graphics. </li></ul>
