10 Gigabit Ethernet Technology.
presented by Qualitia. 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
(GbE) Standard (802.3ae). Evolution of 10 Gigabit Ethernet 10 Gigabit Ethernet (10GbE) Technology Overview
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. 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 ratio 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). 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. Using Fiber in 10 GbE
Two types of optical fiber: multi-mode 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).
