whitepaper Air Distribution Architecture Options for Mission Critical Facilities2009-04-08 American Power Conversion (APC)
  There are nine basic ways to use air to cool equipment in data centers and network rooms. These methods vary in performance, cost, and ease of implementation. These methods are described along with their various advantages. The proper application of these cooling techniques is essential knowledge for Information Systems personnel as well as Facilities Managers.

whitepaper Free Software Trial Allows Capacity Planning for VMware2009-03-04 Vkernel
  In virtual server environments where all resource capacity (CPU, memory, storage, network) is shared, simple additions and changes can drastically affect server performance. For proper capacity planning of your VMware ESX infrastructure, you need a capacity modeling tool that emulates your dynamic data center. The patent-pending VKernel Modeler enables you to quickly simulate and validate hundreds of real-world "what if" scenarios in an interactive sandbox before going live in your production environment. By knowing the potential current and future performance impact ahead of adding virtual machines (VMs), changing capacity configurations, VMotioning servers, and much more, you will have the confidence to virtualize more and avoid costly and time-consuming problems.

whitepaper What is a Network Switch vs. a Router?2009-02-25 Cisco Systems
  What is a network switch and what is a router? The two pieces of equipment look similar and perform some similar functions, but each has its own distinct function to perform on a network.

whitepaper Service Performance and Analysis in Cloud Computing2009-02-14 North Carolina State University
  Cloud computing is a new cost-efficient computing paradigm in which information and computer power can be accessed from a Web browser by customers. Understanding the characteristics of computer service performance has become critical for service applications in cloud computing. For the commercial success of this new computing paradigm, the ability to deliver Quality of Services (QoS) guaranteed services is crucial. This paper presents an approach for studying computer service performance in cloud computing. Specifically, in an effort to deliver QoS guaranteed services in such a computing environment, one finds the relationship among the maximal number of customers, the minimal service resources and the highest level of services.

whitepaper Juniper Networks EX Series Ethernet Switches: QoS-Enabling the Enterprise - Assuring End-to-End Application Performance2009-02-01 Juniper Networks
  Building a multiservice network is a strategic initiative that shouldn't be stymied by QoS pitfalls. Juniper Networks designed the EX3200, EX4200 and EX8200 switches to simplify creating a converged infrastructure. The EX Series switches enable enterprises to deliver predictable performance for any combination of traffic with the least possible administrative overhead. By supporting a common set of QoS features from the access layer to the core, Juniper allows enterprises to follow best practices for ensuring consistent end-to-end QoS. For example, robust QoS features in access devices (whether the EX3200 or EX4200) means that network traffic can be classified and policed at the source. Likewise, standard Layer 3 support on all Juniper switch and router platforms means enterprises have the option to use DSCP marking end-to-end.

whitepaper Understanding Quality of Service on the Catalyst 6500 Switch2009-02-01 Cisco Systems
  This paper explains the Quality of Service (QoS) capabilities available in the Catalyst 6500 Switch as it applies to PFC QoS for IPv4 data. This paper does not cover QoS features on the WAN linecards like the FlexWAN, OSM and SIP modules, nor does it cover QoS for MPLS. This paper covers QoS configuration capabilities and provides some examples of QoS implementation.

whitepaper Mechanism for Per-Class QoS Monitoring in IP/MPLS Transport Networks2009-01-28 Technical University of Catalonia
  This paper presents a study on the usage of MPLS as the technology for transport networks which have to be sensitive to IP Differentiated Services. Advantages of MPLS for implementing Traffic Engineering and the capabilities that lead it towards integration with IP-DiffServ are discussed. Several solutions for DS-TE MPLS are exposed. On the other hand, a mechanism for monitoring classes of service per node in DS-TE MPLS networks is presented.

whitepaper Why Install IPv6 Instead Of IPv4?2009-01-16 Global Knowledge
  The original framers of ARPAnet did not foresee the growth of what is now known as the Internet, or that the IPv4 address structure would fall short of the addresses needed, or all the new devices that would need IP addressing. Consequently, the IPv4 addresses are being exhausted. IPv6 satisfies the increasingly complex requirements of hierarchical addressing that IPv4 does not provide. This white paper explains why a transition from IPv4 to IPv6 can be beneficial.

whitepaper End-to-End QoS Over Internet2009-01-12 Indian Institute of Technology Bombay
  The problem of end-to-end Quality of Service (QoS) over internet can be split into two parts: The first part is to develop framework for information exchange, signaling, path selection and setup spanning across multiple Autonomous Systems (ASes). The second part is to find an optimal inter-domain path based on specific QoS requirements and available resources. The traditional QoS mechanisms try to solve the later part under the constraints under existing Internet. This paper proposes a generalized framework that addresses the first and also simplifies the second. The paper discusses modern scenarios that require end-to-end QoS over internet. It describes the issues involved with QoS mechanisms using existing BGP-based framework then, proposes evolutionary framework to address them.
