INTRODUCTION Ø Most networking technologies will have their day in the spotlight. Ø They will work for several years, but will be replaced with newer, faster technologies as they become available. Ø They will make their mark in telecommunications history and be a topic that will be discussed in many college courses. 3

INTRODUCTION Ø That is not the case for Ethernet - Why ? !!!! Ø 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 customerdriven investment. 4

HISTORY Ø The original Ethernet was developed as an experimental coaxial cable network in the 1970 s 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. Ø 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. 5

HISTORY ØOfficial Ethernet standard (ANSI/IEEE Std. 802. 3) was approved by the 802. 3 working group in 1983. ØSince 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. 6

HISTORY History of Ethernet 7

DEFINITION AND FEATURES Ø 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. Ø Ø Three data rates are currently defined for operation over optical fiber and twisted-pair cables: ä 10 Mbps 10 Base-T Ethernet ä 100 Mbps Fast Ethernet ä 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 8

DEFINITION AND FEATURES Ø 10 -Gigabit Ethernet is under development and will likely be published as the IEEE 802. 3 ae supplement to the IEEE 802. 3 base standard in late 2001 or early 2002. Ø Ethernet has survived as the major LAN technology (it is currently used for approximately 85 percent of the world’s LAN-connected PCs and workstations) because its protocol has the following Characteristics: q q 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. 9

ARCHITECTURE PHYSICAL Ethernet architecture divides the Physical layer into: q Physical Media Dependent (PMD). o q For example : Optical transceivers. Physical Coding Sublayer (PCS). o For example : m. Bn. B code ( 64 B 66 B ). 10

ARCHITECTURE PHYSICAL Ø 10 Gb. E Can Work In: q The LAN PHY. q The WAN PHY. Ø These Phys Are Distinguished Only By The Physical Encoding Sublayer (PCS). 11

ARCHITECTURE Ø The 10 Gigabit LAN PHY can support: q existing Gigabit Ethernet applications. q supports connections to existing and future installations of SONET/SDH (Synchronous Optical Network/ Synchronous Digital Hierarchy). 12

ARCHITECTURE DATA LINK Ø The o Ethernet Mac Sublayer Data encapsulation, including frame assembly before transmission, and frame parsing/error detection during and after reception o Media access control, including initiation of frame transmission and recovery from transmission failure 13

ARCHITECTURE DATA LINK Ø The o 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 protocol’s basic capability. The basic data frame format contains the seven fields. 14

APPLICATIONS Ø LAN q In a medical cancer center 10 Gb. E 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 10 Gb. E can traverse. Ø WAN q The ability to use 10 Gb. E in WAN applications could make it the technology of choice for corporations, Internet service providers and network service providers. 16

APPLICATIONS Ø MAN q Most MANs currently use SONET technology. 10 Gb. E has the following advantages over SONET: o Reduced cost and complexity: o Backbone bandwidth of 10 Gbps o Fewer network elements o Fewer network protocols o Simpler network architecture 17

APPLICATIONS Ø SAN q Fiber Channel has been the technology of choice for storage until 10 Gb. E came into play. There are three factors that could make IPbased storage using i. SCSI a low-cost alternative to Fiber Channel. The following advantages for using 10 Gb. E in SANs are: o Lower costs of 10 Gb. E on server ports and storage array ports o IP-based storage is not as complex as Fiber Channel o IT staff typically have more experience with IP and Ethernet 18

CONCLUSION ADVANTAGES OF 10 Gb. E 1. Increasing network traffic q 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 2. Higher bandwidth and low latency in a single 10 Gb. E server adapter are advantageous in a variety of data-center applications, such as grid computing, high-performance computing (HPC) clusters and wiring cabinet interconnects 19

CONCLUSION ADVANTAGES OF 10 Gb. E 3. The greater speed and faster response of 10 Gb. E can benefit virtually any traffic-burdened network. q E. g. graphics-intensive animation films. 20
