MEDIA ALERT Ethernet Alliance® Hosts Third IEEE 802.1 Data Center Bridging Interoperability Test Event Participation is Open to Both Ethernet Alliance Members and Non‐Members WHAT: The Ethernet Alliance Ethernet in the Data Center Subcommittee has announced it will host an IEEE 802.1 Data Center Bridging (DCB) interoperability test event the week of May 23 in Durham, NH at the University of New Hampshire Interoperability Lab. The Ethernet Alliance invites both members and non‐members to participate in this third DCB test event that will include both protocol and applications testing. The event targets interoperability testing of Ethernet standards being developed by IEEE 802.1 DCB task force to address network convergence issues. Testing of protocols will include projects such as IEEE P802.1Qbb Priority Flow Control (PFC), IEEE P802.1Qaz Enhanced Transmission Selection (ETS) and DCB Capability Exchange Protocol (DCBX). The test event will include testing across a broad vendor community and will exercise DCB features across multiple platforms as well as exercise higher layer protocols such as Fibre Channel over Ethernet (FCoE), iSCSI over DCB, RDMA over Converged Ethernet (RoCE) and other latency sensitive applications. WHY: These test events help vendors create interoperable, market‐ready products that interoperate to the IEEE 802.1 DCB standards. WHEN: Conference Call for Interested Participants: Friday, March 4 at 10 AM PST Event Registration Open Until: March 4, 2011 Event Dates (tentative): May 23‐27, 2011 WHERE: University of New Hampshire Interoperability Lab (UNH‐IOL) Durham, NH WHO: The DCB Interoperability Event is hosted by the Ethernet Alliance. REGISTER: To get more information, learn about participation fees and/or register for the DCB plugfest, please visit Ethernet Alliance DCB Interoperability Test Event page or contact [email protected].

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.

Ethernet Alliance Document
Toward Higher-Speed Modular Interconnection Compatibility Contributors: Greg McSorley, Amphenol John D’Ambrosia, Dell Executive Summary Driven by the ever-increasing server speeds and storage explosion, enterprises today are migrating infrastructures from 10 Gb/s to 40 Gb/s and establishing a framework for 100 Gb/s systems. A basic building block of this framework is the development of a high-speed modular (HSM) port approach, which will enable data centers to pick and choose the physical-layer specifications that will deliver the performance needed at the right cost point. The HSM concept has been implemented for both 40 Gigabit Ethernet (GbE) and 100GbE, allowing networks to continue to scale with rate without causing major architectural changes. This technical brief will provide an overview of the HSM approach, helping users take maximum advantage of the 40GbE and 100GbE architecture to come up with the appropriate interconnects and cost-effectively select from multiple vendors where interoperability can be ensured. Introduction IEEE 802.3™-2012 “Standard for Ethernet” defines a number of physical-layer specifications, including 40GBASE-CR4 and 100GBASE-CR10, which target twin-axial cabling, as well as optional electrical interfaces. The first of those optional interfaces, an Attachment Unit Interface (AUI), is intended for retimed applications, while the Parallel Physical Interface (PPI) is designed for non-retimed applications.1 HSM is envisioned as a kind of universal port type for the globally expanding Ethernet ecosystem. This powerful concept is being leveraged by system vendors to create ports capable of supporting a single form factor that can be populated with different modules that are each capable of supporting a specific physical-layer specification, such as multi-mode fiber, single-mode fiber, twin-axial copper cable or even an active cable solution.
