  1973 at Xerox PARC.

10 GbE STANDARD

• Under the International Standards Organizations
  Open Systems Interconnection (OSI) model,
  Ethernet is fundamentally a Layer 2 protocol.
• IEEE 802.3ae was adapted to include 10-Gbps
  full-duplex transmission over fiber-optic cable.
• 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.
• 10 Gigabit Ethernet remains true to the original
  Ethernet model.

10 GbE ARCHITECTURES

• 10 Gigabit Ethernet uses two separate encoding
  steps.
• The encoded data provides synchronization,
  efficient usage of bandwidth, and improved
  signal-to-noise ratio characteristics.
• All 10GbE varieties use optical fiber media.

10 GIGABIT ETHERNET TECHNOLOGY
CHIP INTERFACE(XAUI)

• 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.
• 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.

10 GIGABIT ETHERNET TECHNOLOGY
PHYSICAL MEDIA DEPENDENTS(PMDs)

• 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.

11
10 GIGABIT ETHERNET TECHNOLOGY
PHYSICAL LAYER(PHYs)

• The LAN PHY and the WAN PHY will operate over
  common PMDs and, therefore, will support the same
  distances. .
• The 10 Gigabit LAN PHY is intended to support
  existing Gigabit Ethernet applications at ten
  times the bandwidth with the most cost-effective
  solution.
• 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.

10 GIGABIT ETHERNET TECHNOLOGY
APPLICATIONS FOR 10 GbE
10 Gigabit Ethernet in Local Area Networks

• Ethernet technology is already the most deployed
  technology for high performance LAN environments.
  
• 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.
• 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.

10 GIGABIT ETHERNET TECHNOLOGY
APPLICATIONS FOR 10 GbE
10 GbE in Metropolitan and Storage Area Networks

• Gigabit Ethernet is already being deployed as a
  backbone technology for dark fiber metropolitan
  networks. With appropriate 10 Gigabit Ethernet
  interfaces, optical transceivers and single mode
  fiber, service providers will be able to build
  links reaching 40km or more.
• 10 Gigabit Ethernet will provide infrastructure
  for both network-attached storage (NAS) and
  storage area networks (SAN).

14
10 GIGABIT ETHERNET TECHNOLOGY
APPLICATIONS FOR 10 GbE
10 Gigabit Ethernet in Wide Area Networks

• 10 Gigabit Ethernet will enable Internet service
  providers (ISP) and network service providers
  (NSPs) to create very high-speed links at a very
  low cost, between co-located, carrier-class
  switches and routers and optical equipment that
  is directly attached to the SONET/SDH cloud.
• 10 Gigabit Ethernet with the WAN PHY will also
  allow the construction of WANs that connect
  geographically dispersed LANs between campuses or
  POPs (points of presence) over existing
  SONET/SDH/TDM networks.

15
10 GIGABIT ETHERNET TECHNOLOGY
APPLICATIONS FOR 10 GbE
10 Gigabit Ethernet as a Fabric Interconnect
10 Gigabit Ethernet is in a position to replace
all these proprietary technologies as a
next-generation interconnect for both server and
storage-area networks for several reasons

• Cost-Saving Server Consolidation.
• 10 Gigabit Ethernet Offers the Necessary
  Bandwidth.
• Planned Growth of 10 Gigabit Network Features.

16
10 GIGABIT ETHERNET TECHNOLOGY
USING FIBER IN 10GbE

• There are two types of optical fiber, multimode
  and single mode fiber, that are currently used in
  data networking and telecommunications
  applications.
• The 10 Gigabit Ethernet technology, as defined in
  the IEEE 802.3ae standard, supports both optical
  fiber types.
• However, the distances supported vary based on
  the type of fiber and wavelength (nm) is
  implemented in the application.

THE FUTURE OF 10GbE
Will There be Copper?

• IEEE 802.3 has recently formed two new study
  groups to investigate 10 Gigabit Ethernet over
  copper cabling.
• The 10GBASE-CX4 study group is developing a
  standard for transmitting and receiving XAUI
  signals via a 4-pair twinax cable, commonly
  referred to as a 4x InfiniBand cable.
• The 10GBASE-T study group is developing a
  standard for the transmission and reception of 10
  Gigabit Ethernet via a Category 5 or better
  unshielded twisted pair (UTP) copper cable up to
  100 m.

• 10 Gigabit Ethernet is very much necessary for
  todays network and is viable now.
• 10 Gigabit Ethernet forms the backbone of todays
