Ethernet Alliance Hosts Third IEEE 802.1 Data Center Bridging
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.

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. -

Generating Synthetic Voip Traffic for Analyzing Redundant Openbsd
UNIVERSITY OF OSLO Department of Informatics Generating Synthetic VoIP Traffic for Analyzing Redundant OpenBSD-Firewalls Master Thesis Maurice David Woernhard May 23, 2006 Generating Synthetic VoIP Traffic for Analyzing Redundant OpenBSD-Firewalls Maurice David Woernhard May 23, 2006 Abstract Voice over IP, short VoIP, is among the fastest growing broadband technologies in the private and commercial sector. Compared to the Plain Old Telephone System (POTS), Internet telephony has reduced availability, measured in uptime guarantees per a given time period. This thesis makes a contribution towards proper quantitative statements about network availability when using two redun- dant, state synchronized computers, acting as firewalls between the Internet (WAN) and the local area network (LAN). First, methods for generating adequate VoIP traffic volumes for loading a Gigabit Ethernet link are examined, with the goal of using a minimal set of hardware, namely one regular desktop computer. pktgen, the Linux kernel UDP packet generator, was chosen for generating synthetic/artificial traffic, reflecting the common VoIP packet characteristics packet size, changing sender and receiver address, as well as typical UDP-port usage. pktgen’s three main parameters influencing the generation rate are fixed inter-packet delay, packet size and total packet count. It was sought to relate these to more user-friendly val- ues of amount of simultaneous calls, voice codec employed and call duration. The proposed method fails to model VoIP traffic accurately, mostly due to the cur- rently unstable nature of pktgen. However, it is suited for generating enough packets for testing the firewalls. Second, the traffic forwarding limit and failover behavior of the redun- dant, state-synchronized firewalls was examined. -

Synchronous Ethernet Solutions with Altera Fpgas and Silicon Labs Jitter-Attenuating Plls
Synchronous Ethernet Solutions with Altera FPGAs and Silicon Labs Jitter-Attenuating PLLs Hoss Rahbar, Product Marketing Manager, Altera Han Hua Leong, Design Engineer, IP and Device Software Engineering, Altera Bill Simcoe, Marketing Manager, Silicon Labs WP-01257-1.0 White Paper Introduction Synchronous clock signals are required for proper operation of voice communications, cellular wireless networks, passive optical networks (PONs), and a variety of other time-critical networking applications. Traditional time division multiplexed (TDM) telecom equipment—to support standards like Synchonous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH)—operate with synchronized clock signals. Nodes in these networks are synchronized to a primary reference clock (PRC) or primary reference source (PRS) with long-term frequency accuracy better than 1 part in 1011. The PRS/PRC clocks in TDM networks are provided by highly accurate and stable atomic clocks, or signals from the global positioning system (GPS). The clocks are then distributed to all the nodes in the network over the same connections that transport clients’ voice and data. The network nodes then synchronize their locally generated clocks to the PRS/PRC clock. Ethernet has become the network interface of choice in enterprise, metro, and some core networks. Ethernet networks can be used to transport voice, data, and video at high data rates for substantially lower equipment and service costs than traditional networks. Large capital savings can be realized by using Ethernet for synchronizing network nodes instead of using a more expensive specialized synchronous network. The IEEE 802.3 Ethernet standard is not specified to accurately transfer a clock from the transmitter to the receiver. -

Any-to-any communications of new intranet applications such as video to the desktop, interactive messaging, and collaborative white-boarding are increasing the need for scalable bandwidth within the core and at the edge of campus networks. At the same time, mission-critical applications call for resilient network designs.
