whitepaper Gb Ethernet Protocols for Clusters: An OpenMPI, TIPC, GAMMA Case Study2008-03-17 John von Neumann Institute for Computing
  Gigabit Ethernet is a standard feature of cluster machines. Provision of fast network interconnects is negated if communication software cannot match the available throughput and latency. Transparent Inter Process Communication (TIPC) has been proposed as an alternative to TCP in terms of reduced message latency and system time. This study compares through low-level tests and application benchmarks the relative performance of TIPC, Open MPI, and also what improvement the GAMMA User-Level Network interface can bring compared to both of these. TIPC's system time usage is reduced compared to TCP, leading to computational gains, especially on loaded cluster nodes. GAMMA is shown to bring significant improvement in computational performance on an unloaded cluster but a more flexible alternative is Open MPI running over TIPC.

whitepaper Building High-End Ethernet Functionality Into SDH Networks2008-03-05 Tejas Networks
  For now, NG-SDH seems to have its roots firmly entrenched in Service Provider networks. Given the ubiquitous presence of SDH in the metro, incrementally offering high-end Ethernet services over this SDH network would be the best way of packetizing the metro. This approach ensures that the Service Provider can start offering risky but more profitable data services without letting go of 'Cash cow' voice services. The incremental nature of this approach should also alleviate the risk of introducing these new data services into the network. The high comfort-levels Network Operators have with NG-SDH, and NG-SDH's strong OAM features, combine well with the flexibility and efficiency of Ethernet to give the Service Provider the best of both worlds.

whitepaper 10-Gigabit Ethernet - The Next Generation Network Infrastructure2008-01-24 Dell
  Since any opportunity to improve performance is a plus for IT administrators, the dawning of 10-Gigabit Ethernet (10-GigE) is good news. Questions regarding costs, benefits, cabling, and timing are top of mind as administrators try to plan technology upgrades and new network deployments.

Rest assured that if you have not already implemented 10-GigE, you're not late -- while some organizations have begun to use it, cabling upgrades will be required to drive broader deployment.

whitepaper Data Center Ethernet: Cisco's Innovation for Data Center Networks2008-03-01 Cisco Systems
  Cisco has developed standards-based extensions to Ethernet for data center networks to support new capabilities. This paper talks about Cisco's continuing innovations in Ethernet data center networks to provide support for new application demands. The paper also talks about the Cisco Data Center Ethernet architecture enhancements that improve the robustness of Ethernet and support new concepts such as unified I/O and unified fabrics. It shows where other approaches have fallen short, and how Cisco Data Center Ethernet promises to be the architecture that fulfills the requirements for the next generation of Ethernet networks in the data center.

whitepaper Cisco Carrier Ethernet Management2008-03-01 Cisco Systems
  This paper introduces Cisco solutions that are available for managing Carrier Ethernet networks. It will help to determine the best solution based on their organization's size, requirements, and budget. To accommodate different needs, two types of solutions are proposed: the "Jump-Start Solution" and the "Complete Solution." The paper describes a full lifecycle services approach available through Cisco Advanced Services for service providers.

whitepaper TIA-942 Data Center Networking Applications: 10 Gigabit Ethernet Over Twisted-Pair Copper2008-02-19 Solarflare Communications
  In parallel and subsequent to the development of TIA-942, the IEEE 802.3 Ethernet working group published two twisted-pair copper standards, 1000 Mb/s Ethernet designated 1000BASE-T and 10 Gb/s Ethernet (10 GbE) designated 10GBASE-T, both standards are targeted at meeting the increasing bandwidth requirements for data center applications. This white paper will discuss the TIA-942 Data Center standard with emphasis on data center cabling and 10GBASE-T twisted-pair Ethernet data center applications.

whitepaper The Kentucky Department of Education Is Leveraging Information Technology to Take Educational Opportunities to New Heights With a Flexible, Robust and Secure Nortel Solution2008-02-14 Nortel Networks
  Through the Kentucky Department of Education, the Office of Education Technology laid out its "2007-2012 Education Technology Master Plan" with the objectives of providing equal access to technology for all teachers and students, enhancing their teaching and learning experiences in Kentucky's classrooms, and to thereby prepare all Kentucky children to be productive and contributing members of a modern workforce. The Master Plan was designed to both replenish an eroding infrastructure and introduce "New, mission-oriented solutions." Nortel was able to deliver the right technology, to help the Kentucky Department of Education map out the right solution and to then help support that solution - all of which has allowed the state to meet its objectives.

whitepaper Multimedia Polska SA (Poland) Choose Allied Telesis for Triple Play2008-02-07 Allied Telesis
  Multimedia is one of the most innovative Polish Service Providers, and is among the first to introduce IP based Triple Play (Data, Voice and Video), Video on Demand (VoD), and High Definition TV (HDTV). Multimedia needed to build a network that could be scaled to cover the entire country of Poland. Additionally, Gigabit Ethernet was required, to provide the necessary throughput for video, high definition video and data. After evaluating a number of vendors, Multimedia selected two products from Allied Telesis - the AT-9924T, a 24 copper port Gigabit Layer 3 switch, and the AT-9924SP switch, an SFP port version that is compatible with a wide range of optical modules.

whitepaper Enhanced Power Over Ethernet: Easier Deployment and Improved Mobility2008-02-01 Cisco Systems
  Cisco was the first to develop the capability of providing power to the network end device when it enabled a means of providing power from an Ethernet switch port to its Cisco IP phone. From there, Cisco began work with numerous other vendors within the IEEE to create a standards-based means of providing power from an Ethernet switch port. This Power over Ethernet (PoE) capability has been ratified by the IEEE 802.3af committee and is now widely adopted. Cisco is continuing to promote the evolution of technology innovation by delivering Cisco Enhanced PoE, another industry innovation. Cisco Enhanced PoE is Cisco's extension to the IEEE 802.3af standard that supplies greater amounts of power per port.   
whitepaper Secure Industrial Control Utilizing High Speed Ethernet Networks and Web Management2008-01-31 GarrettCom
  This paper explores the state of network security options today at the Ethernet switch level and offers an elementary roadmap for industrial operations to plan for and deploy secure communications systems. Industrial systems need to take advantage of the advanced networking technologies that can support greater efficiency, reliability, and security in plant and remote operations. As SCADA systems, relays, and other industrial control, monitoring and management systems become more intelligent, a rich supply of data is available for improving plant performance and remote maintenance and management.
