INTRODUCTION

• Most networking technologies will have their day
  in the spotlight.
• They will work for several years, but will be
  replaced with newer, faster technologies as they
  become available.
• They will make their mark in telecommunications
  history and be a topic that will be discussed in
  many college courses.

INTRODUCTION

• That is not the case for Ethernet - Why ?!!!!
• Ethernet has managed to secure its position as a
  networking technology of choice in the customer
  domain and is therefore a desirable choice in the
  service-provider domain to eliminate potential
  inter-working problems and leverage the
  customer-driven investment.

5
HISTORY

• The original Ethernet was developed as an
  experimental coaxial cable network in the 1970s
  by Xerox Corporation in their Pall Alto Research
  Center to operate with a data rate of 2.94 Mbps
  using a carrier sense multiple access collision
  detect (CSMA/CD) protocol for LANs with sporadic
  but occasionally heavy traffic requirements.
• Joint development of the 10-Mbps Ethernet
  Version 1.0 specification by the three-company
  consortium Digital Equipment Corporation, Intel
  Corporation, and Xerox Corporation in 1980.

6
HISTORY

• Official Ethernet standard (ANSI/IEEE Std. 802.3)
  was approved by the 802.3 working group in 1983.
• Since then, a number of supplements to the
  standard have been defined to take advantage of
  improvements in the technologies and to support
  additional network media and higher data rate
  capabilities, plus several new optional network
  access control features.

DEFINITION AND FEATURES

• Ethernet refers to the family of local-area
  network (LAN) products covered by the IEEE 802.3
  standard that defines as the CSMA/CD protocol.
• Three data rates are currently defined for
  operation over optical fiber and twisted-pair
  cables
• 10 Mbps 10Base-T Ethernet
• 100 Mbps Fast Ethernet
• 1000 Mbps Gigabit Ethernet
• 10-Gigabit Ethernet technology is the next step
  for scaling the performance and functionality of
  enterprise and service provider networks because
  it combines multi-gigabit bandwidth and
  intelligent services in order to achieve scaled,
  intelligent, multi-gigabit networks with network
  links that range in speed from 10 Mbps to 10,000
  Mbps

9
DEFINITION AND FEATURES

• 10-Gigabit Ethernet is under development and will
  likely be published as the IEEE 802.3ae
  supplement to the IEEE 802.3 base standard in
  late 2001 or early 2002.
• Ethernet has survived as the major LAN technology
  (it is currently used for approximately 85
  percent of the worlds LAN-connected PCs and
  workstations) because its protocol has the
  following Characteristics
• Is easy to understand, implement, manage, and
  maintain
• Allows low-cost network implementations
• Provides extensive topological flexibility for
  network installation
• Guarantees successful interconnection and
  operation of standards-compliant products,
  regardless of manufacturer.

ARCHITECTURE

• PHYSICAL
• Ethernet architecture divides the Physical layer
  into
• Physical Media Dependent (PMD).
• For example Optical transceivers.
• Physical Coding Sublayer (PCS).
• For example mBnB code ( 64B66B ).

11
ARCHITECTURE

• PHYSICAL
• 10 GbE Can Work In
• The LAN PHY .
• The WAN PHY .
• These Phys Are Distinguished Only By The Physical
  Encoding Sublayer (PCS).

12
ARCHITECTURE

• The 10 Gigabit LAN PHY can support
• existing Gigabit Ethernet applications.
• supports connections to existing and future
  installations of SONET/SDH (Synchronous Optical
  Network/ Synchronous Digital Hierarchy).

13
ARCHITECTURE

• DATA LINK
• The Ethernet Mac Sublayer
• Data encapsulation, including frame assembly
  before transmission, and frame parsing/error
  detection during and after reception
• Media access control, including initiation of
  frame transmission and recovery from transmission
  failure

14
ARCHITECTURE

• DATA LINK
• The Basic Ethernet Frame Format
• The IEEE 802.3 standard defines a basic data
  frame format that is required for all MAC
  implementations, plus several additional optional
  formats that are used to extend the protocols
  basic capability. The basic data frame format
  contains the seven fields.

APPLICATIONS

• LAN
• In a medical cancer center 10GbE has been
  utilized throughout its campus to connect 10
  buildings and outlying clinics. It will be used
  to support real-time, video collaboration between
  surgeons and specialists throughout the Center.
  This company is taking advantage of the extra
  distance that 10GbE can traverse.
• WAN
• The ability to use 10GbE in WAN applications
  could make it the technology of choice for
  corporations, Internet service providers and
  network service providers.

17
APPLICATIONS

• MAN
• Most MANs currently use SONET technology. 10GbE
  has the following advantages over SONET
• Reduced cost and complexity
• Backbone bandwidth of 10 Gbps
• Fewer network elements
• Fewer network protocols
• Simpler network architecture

18
APPLICATIONS

• SAN
• Fiber Channel has been the technology of choice
  for storage until 10GbE came into play. There are
  three factors that could make IP-based storage
  using iSCSI a low-cost alternative to Fiber
  Channel. The following advantages for using 10GbE
  in SANs are
• Lower costs of 10GbE on server ports and storage
  array ports
• IP-based storage is not as complex as Fiber
  Channel
• IT staff typically have more experience with IP
  and Ethernet

19
CONCLUSION ADVANTAGES OF 10 GbE

• Increasing network traffic
• higher bandwidth allows faster data flow to and
  from network servers, resulting in faster
  transaction servicing and completion, which frees
  the servers for handling more transactions faster
• Higher bandwidth and low latency in a single
  10GbE server adapter are advantageous in a
  variety of data-center applications, such as grid
  computing, high-performance computing (HPC)
  clusters and wiring cabinet interconnects

20
CONCLUSION ADVANTAGES OF 10 GbE

• The greater speed and faster response of 10GbE
  can benefit virtually any traffic-burdened
  network.
• E.g. graphics-intensive animation films.
