10 Gigabit Ethernet Technology   Description: This presentation shows the use of 10 Gigabit Ethernet Technology   10 Gigabit Ethernet (10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10 Gigabit Ethernet defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations Ethernet standards[1] so half-duplex operation and repeater hubs do not exist in 10GbE.

Introduction
• Ethernet is a wire-based network technology
protocol that controls how data is transmitted over a
LAN
• It finds its applications in LAN, MAN, WAN as well as
SAN.
• Provides high speed and reliable network, low
installation and maintenance cost.

History
• Developed by Robert M. Metcalfe and David R. Boggs
in late 1972 at Xerox PARC.
• The original 10 Mbps Ethernet standard was first
published in 1980 by the DEC-Intel-Xerox vendor
consortium.
• In June 2002, IEEE adopted 10 Gigabit Ethernet
Standard (802.3ae).

10 Gigabit Ethernet Technology
Overview ( 10GbE )
• Retention of 802.3 MAC and frame format
~64-1518 byte frames.
~jumbo-frames are not included in standard.
• No half duplex mode
~different from other versions of Ethernet.
• No CSMA/CD on full duplex
~Simultaneous sending and receiving at all times.

7. 7
• Works with 802.1Q, 802.3ad,etc.
• Fiber interfaces only- no copper versions.
• LAN PHY- 10Gb/s.
• WAN PHY- 9.29 Gb/s (SONET framing overhead)

10 Gigabit Ethernet Standard
• Under the International Standards Organization’s
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
(MAC) protocol, the IEEE 802.3 Ethernet frame
format, and the min and max IEEE 802.3 frame size.
• 10 Gigabit Ethernet remains rue 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 ration characteristics.
• All 10GbE varieties use optical fiber media.

Applications For 10GbE
10 Gigabit Ethernet in Local Area Networks.
• With the extension of 10 Gigabit Ethernet into the
family of Ethernet technologies, the LAN now can reach
farther and support upcoming 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 too.

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 and 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).

12. 12
10 Gigabit Ethernet in Wide Area Networks.
• 10 GbE will enable ISPs 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 WAN’s that connect geographically
dispersed LANs between campuses or POPs(points of
presence) over existing SONET/SDH/TDM networks.

10 Gigabit Ethernet as a Fabric Interconnect.
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.
Cont.……

14. 14
Using Fiber In 10 GbE
• Two types of optical fiber: multimode and single mode
fiber, that are currently being used in data networking
and telecommunications applications.
• 10GbE technology, as defined in the IEEE 802.3ae
standard, supports both optical fiber types.
• However, the distances supported may vary based on
the type of fiber and wavelength (nm) implemented in
the application.

The Future Of 10 GbE
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 stand 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 % or better unshielded twisted pair (UTP) copper
cable up to 100m.

10 GbE Market Overview
• Extension of existing Ethernet family of standards.
• Another 10x jump for higher capacity.
• Typical Ethernet applications at higher speed.
• Also positioned as MAN/WAN technology for use
over dark fiber or SONET/SDH.

Conclusion
• Potentially lowest total cost of ownership
(infrastructure/operational/human capital).
• Straightforward migration to higher performance
levels.
• Proven multi-vendor and installed base
interoperability (Plug and Play).
• Familiar network management feature set.
