40 and 100 Gigabit Ethernet Overview
Extreme Networks White Paper 40 and 100 Gigabit Ethernet Overview Abstract This paper takes a look at the main forces that are driving Ethernet bandwidth upwards. It looks at the standards and architectural practices adopted by the different segments, how the different speeds of Ethernet are used and how its popularity has resulted in an ecosystem spanning data centers, carrier networks, enterprise networks, and consumers.

Gigabit Ethernet - CH 3 - Ethernet, Fast Ethernet, and Gigabit Ethern
Switched, Fast, and Gigabit Ethernet - CH 3 - Ethernet, Fast Ethernet, and Gigabit Ethern.. Page 1 of 36 [Figures are not included in this sample chapter] Switched, Fast, and Gigabit Ethernet - 3 - Ethernet, Fast Ethernet, and Gigabit Ethernet Standards This chapter discusses the theory and standards of the three versions of Ethernet around today: regular 10Mbps Ethernet, 100Mbps Fast Ethernet, and 1000Mbps Gigabit Ethernet. The goal of this chapter is to educate you as a LAN manager or IT professional about essential differences between shared 10Mbps Ethernet and these newer technologies. This chapter focuses on aspects of Fast Ethernet and Gigabit Ethernet that are relevant to you and doesn’t get into too much technical detail. Read this chapter and the following two (Chapter 4, "Layer 2 Ethernet Switching," and Chapter 5, "VLANs and Layer 3 Switching") together. This chapter focuses on the different Ethernet MAC and PHY standards, as well as repeaters, also known as hubs. Chapter 4 examines Ethernet bridging, also known as Layer 2 switching. Chapter 5 discusses VLANs, some basics of routing, and Layer 3 switching. These three chapters serve as a precursor to the second half of this book, namely the hands-on implementation in Chapters 8 through 12. After you understand the key differences between yesterday’s shared Ethernet and today’s Switched, Fast, and Gigabit Ethernet, evaluating products and building a network with these products should be relatively straightforward. The chapter is split into seven sections: l "Ethernet and the OSI Reference Model" discusses the OSI Reference Model and how Ethernet relates to the physical (PHY) and Media Access Control (MAC) layers of the OSI model. -

North China Electric Power University, Department of electronics and Communication Engineering, Baoding, China, 071003 Email:1 [email protected],2 [email protected],3 [email protected] Abstract. By using the dynamic reconfigurable transceiver in high speed interface design, designer can solve critical technology problems such as ensuring signal integrity conveniently, with lower error binary rate. In this paper, we designed a high speed XAUI (10Gbps Ethernet Attachment Unit Interface) to transparently extend the physical reach of the XGMII. The following points are focused: (1) IP (Intellectual Property) core usage. Altera Co. offers two transceiver IP cores in Quartus II MegaWizard Plug-In Manager for XAUI design which is featured of dynamic reconfiguration performance, that is, ALTGX_RECOFIG instance and ALTGX instance, we can get various groups by changing settings of the devices without power off. These two blocks can accomplish function of PCS (Physical Coding Sub-layer) and PMA (Physical Medium Attachment), however, with higher efficiency and reliability. (2) 1+1 protection. In our design, two ALTGX IP cores are used to work in parallel, which named XAUI0 and XAUI1. The former works as the main channel while the latter redundant channel. -
Ipug68 01.3 Lattice Semiconductor XAUI IP Core User’S Guide
ispLever TM CORECORE XAUI IP Core User’s Guide November 2009 ipug68_01.3 Lattice Semiconductor XAUI IP Core User’s Guide Introduction The 10Gb Ethernet Attachment Unit Interface (XAUI) IP Core User’s Guide for the LatticeECP2M™ and LatticeECP3™ FPGAs provides a solution for bridging between XAUI and 10-Gigabit Media Independent Interface (XGMII) devices. This user’s guide implements 10Gb Ethernet Extended Sublayer (XGXS) capabilities in soft logic that together with PCS and SERDES functions implemented in the FGPA provides a complete XAUI-to-XGMII solu- tion. The XAUI IP core package comes with the following documentation and files: • Protected netlist/database • Behavioral RTL simulation model • Source files for instantiating and evaluating the core The XAUI IP core supports Lattice’s IP hardware evaluation capability, which makes it possible to create versions of the IP core that operate in hardware for a limited period of time (approximately four hours) without requiring the pur- chase on an IP license. It may also be used to evaluate the core in hardware in user-defined designs. Details for using the hardware evaluation capability are described in the Hardware Evaluation section of this document. Features • XAUI compliant functionality supported by embedded SERDES PCS functionality implemented in the LatticeECP2M and LatticeECP3, including four channels of 3.125 Gbps serializer/deserializer with 8b10b encod- ing/decoding. • Complete 10Gb Ethernet Extended Sublayer (XGXS) solution based on LatticeECP2M and LatticeECP3 FPGA. • Soft IP targeted to the FPGA implements XGXS functionality conforming to IEEE 802.3ae-2002, including: – 10 GbE Media Independent Interface (XGMII). – Optional Slip buffers for clock domain transfer to/from the XGMII interface. -

100 Gigabit Ethernet Is Here!
100 Gigabit Ethernet is Here! Introduction Ethernet technology has come a long way since its humble beginning in 1973 at Xerox PARC. With each subsequent iteration, there has been a lag between time of standardization and large scale adoption. The latest iteration, dubbed 802.3ba by the IEEE Higher Speed Study Group (HSSG), was ratified in June, 2010 and follows this same pattern but with a slight twist. For the first time in Ethernet history a single standard defines two separate speeds; 100 Gigabit Ethernet (100GbE) as well as 40 Gigabit Ethernet (40GbE). Figure 1: Original Ethernet Sketch The technical challenges facing 100GbE have been significant; ranging from developing a whole new generation of optics that can handle 4 lanes of 25Gbps, to simply dealing with normal router and switch functions such as packet inspection, queuing, lookups, filtering and table updates, all in one-tenth the amount of time as with 10GbE. And of course this all has to be done with complete backwards compatibility and meeting all expectations with respect to bit error rate, latency, jitter and the like. As expected 40GbE gained some level of market acceptance first, but some 5 years after ratification the time for 100 Gigabit Ethernet is now! 2 | P a g e This whitepaper will discuss the evolution of 100GbE technology in the service provider and data center markets and provide insights in to how network application acceleration hardware can be leveraged to maximize performance and efficiency in emerging 100GbE network appliances. 100GbE in Service Providers Networks 100GbE is rapidly approaching large scale adoption in the wide area network (WAN), which is largely the purview of service providers. -

The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted-pair or fiber optic cables. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted-pair PHY types.
