whitepaper How a Spanning Tree Works2009-06-23 Global Knowledge
  The way a switch learns Ethernet (MAC) addresses is by inspecting the Ethernet frame and recording the source MAC address in a dynamic table. The switch will also associate a learned MAC address with a port. It can then make intelligent forwarding decisions based on the destination MAC address. This white paper illustrates the process. This white paper focuses on Spanning Tree Protocol (STP), IEEE Standard 802.11, and addresses the functions of an Ethernet LAN switch.

whitepaper TANDBERG MCU and IP2009-06-17 Tandberg
  H.323 is an International Telecommunications Union (ITU) standard that describes the protocols, services and equipment necessary for multimedia communications including audio, video and data on networks without guaranteed Quality of Service (QoS). These networks technologies may include Ethernet, Fast Ethernet, and Token Ring and protocols like Internet Protocol (IP) or Integrated Packet Exchange (IPX). Due to the need to communicate between smaller networks connected to the Internet, IP will be a more popular transport for H.323. Today, the dominant method of Internet communications is email. However, there is a growing need to increase communications to include audio, video and data. The explosion of the Internet in the early 1990's has paved the way to higher bandwidth connections to corporate offices, universities and even to the home. Now that the bandwidth is available, the demand for multimedia communications over the Internet is growing. TANDBERG D2 software now enables IP conferencing on the TANDBERG MCU.

whitepaper TANDBERG and Packet Loss2009-06-17 Tandberg
  This paper is intended to describe the packet loss robustness features available with TANDBERG's products. These features include: Intelligent Packet Loss RecoveryTF (IPLRTF), Downspeeding, Quality of Service (QoS). The above mentioned features are all available on the following products: TANDBERG MCU 16+16 / 8+8, TANDBERG GW, TANDBERG 8000, TANDBERG 7000, TANDBERG 6000, TANDBERG 2500, TANDBERG 1000, TANDBERG 880, TANDBERG 800, TANDBERG 550, TANDBERG 500. The IPLR feature is not intended to replace Quality of Service (QoS) techniques which may be employed on IP networks to reserve bandwidth or set precedence on video traffic. However, in the rare event that QoS techniques fail, IPLR is designed to overcome transient packet loss situations and reduce the impact these losses may have on the current video traffic. To fully understand what IPLR offers, an understanding of QoS and video compression are recommended. This paper briefly describes each before describing the details of TANDBERG's IPLR.

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.
