whitepaper Backgrounder: The Complementarity of Next Generation Networks and Virtualization Projects2008-04-01 Exponential-e
  Virtualization projects currently pay lip-service to the underlying connectivity infrastructure. The current trend is to transition from costly and limited-function "Fibre Channel" and "Leased Line" communication links to more powerful 1Gig or 10Gig Ethernet switched network connections. Whilst Exponential-e can offer the powerful connectivity provided by GigE connections, this is merely the substitution of existing network capacity based on legacy technologies over to Ethernet, which, whilst undoubtedly, has better cost metrics. This paper goes much further by illustrating how an Ethernet-based Next Generation platform will make available to the virtualization manager, an array of features not on offer within a legacy environment.   
whitepaper Ethernet Power Study of Cisco and Competitive Products2008-04-01 Cisco Systems
  Every Ethernet switch requires electricity to function. Efficiency is the measure of power relative to amount of work performed. When products use more power to perform the same amount of work, they are by definition less efficient. Low efficiency creates increased costs for a customer. Other factors that should be considered are heat dissipation and the power required to cool down the system. Heat dissipation is calculated in British thermal units (Btus)2 and is calculated as 3.41 Btus per W of power consumption. An efficient cooling system would consume approximately 0.33 Btus for every Btu cooled, leading to a power consumption of 0.358W for cooling the heat dissipated by 1W.   
whitepaper MPLS Plug-and-Play for Metro Ethernet Networks: Deploying a Carrier-Class MPLS Metropolitan Ethernet Network to Reduce Operating Expense and Network Complexity2008-04-01 Juniper Networks
  This paper will focus on an opportunity to revolutionize the way Metro Ethernet networks are built by applying the concept of MPLS Plug-and-Play, a technology developed by Juniper Networks. MPLS Plug-and-Play offers carriers a way to reduce the operating expense associated with deploying and managing MPLS-based Metro Ethernet networks while still enabling these operators to offer all of the cutting-edge services that their customers increasingly expect. This paper will show carriers how to easily map their access MPLS network into their larger core MPLS network, or, if preferred, how to create a completely new architecture.

whitepaper Redundancy in Serial-to-Ethernet Communications2008-04-01 Digi International
  This paper provides information about redundancy in serial-to-Ethernet communications. It describes technologies from Digi International that eliminate single points of failure for networked devices while also enabling multiple host connections to a single port. It wasn't many years ago that users were ecstatic just to be able to connect a serial device to Ethernet. This technology represented a paradigm shift - information which was previously tethered to a 50-foot RS-232 serial cable could now be made available across TCP/IP Local Area Networks (LANs,) Wide Area Networks (WANs) and even the Internet. However, as users began to depend on access to these islands of information, issues such as connection reliability (uptime) and accessibility became top concerns.

whitepaper Technology Brief: Carrier Vs. Enterprise Ethernet Silicon2008-04-01 Lightstorm Networks
  Ethernet has been the dominant networking protocol in Local Area Networks (LANs) due to its high bandwidth, ease of use, and low cost. Until recently, its success in LANs has not translated to communications networks due to limitations in Ethernet's scalability, reliability, and manageability. With the latest developed standards and Ethernet products specifically built for carrier applications, Ethernet has begun to penetrate applications where TDM, ATM or SONET have been the prevalent solution for many years. This paper will discuss the requirements for carrier-class applications and it will compare and contrast solutions developed using carrier Ethernet silicon versus enterprise silicon products.

whitepaper Power Over Ethernet Plus2008-04-01 Ethernet Alliance
  The standard for Power over Ethernet (PoE), IEEE Std. 802.3af-2003, helped increase the value of an Ethernet port by connecting and powering devices such as IP Phones using a common network infrastructure. An upcoming PoE standard known as Power over Ethernet Plus (PoE Plus) or IEEE P802.3at promises to deliver more power to enable a new breed of Ethernet devices and continue to support IEEE 802.3af. This paper provides an overview of PoE Plus.   
whitepaper PAUSE Power Cycle: A New Backwards Compatible Method to Reduce Energy Use of Ethernet Switches2008-04-01 Ethernet Alliance
  Energy efficient Ethernet switches can provide significant global savings in electricity consumption. The IEEE 802.3az task force (Energy Efficient Ethernet) is exploring methods for scaling Ethernet link rate as a function of utilization to save energy. IEEE 802.3az is studying methods that require both end points of an Ethernet link to implement new mechanisms and policies, thus these methods cannot achieve energy savings with existing Ethernet devices. In this white paper, a new backwards compatible method for achieving energy savings in Ethernet switches is designed, emulated, and evaluated. This new method is called PAUSE Power Cycle (PPC). PPC uses 802.3 PAUSE flow control to cycle Ethernet links between ON and OFF (PAUSEd) states.

whitepaper IQinVision Megapixel Technology and IP Video Surveillance Ensure Security Excellence for DHL2008-03-28 IQinVision
  To keep up with its expanding business throughout Europe, DHL Exel Supply Chain, a global leader in transport, freight, and logistics, built a new logistics center of late. DHL sought a future-proof, scalable video surveillance system, complemented by the best camera technology available, to meet its current needs and possible future expansion. DHL chose an IP-based system with power delivered by external Power-over-Ethernet (PoE) adapters to IP surveillance cameras via lower cost CAT5 Ethernet cabling.

whitepaper Ethernet Network-Based DAQ and Smart Sensors for the OPERA Long-Baseline Neutrino Experiment2008-03-18 AGILENT
  This paper proposes a data acquisition scheme for the OPERA long-baseline neutrino experiment based exclusively on Ethernet. The expected data rate allows the use of an Ethernet capable device close to the sensor. The basic idea is to build a distributed acquisition system on Ethernet, made of about 1000 nodes of 64 channel front-end modules. Each node will be controlled and readout by an embedded Ethernet chip and will be therefore transparently visible on the network. These modules will be directly controlled by the event building computers and will be able to execute a set of embedded functions for slow control monitoring and data readout. The paper presents a first prototype of Ethernet capable front-end module with high speed ADC and TDC capabilities.
