whitepaper Improve Availability and Resiliency with Software Infrastructure Testing by IT Operations2008-08-30 StackSafe
  Does your company know how the next software patch or configuration change will impact uptime? An alarming number of companies cannot be completely sure what any change will do to their critical business applications. Their IT operations teams lack the testing resources and processes to understand the impact of changes and be sure that they won't cause service degradation, or, worse yet, take an application offline completely. And yet today's business environment requires that systems be available 24/7 for people both inside and outside the company. So how can you better understand the impacts of changes to the software infrastructure? And what are the costs associated with testing?

In this webcast, trusted advisors from Gartner and StackSafe discuss the importance of software infrastructure testing to improve uptime. You'll also find out why new technologies like virtualization can make testing easier and more effective.

whitepaper A Scalable, Commodity Data Center Network Architecture2008-08-22 Association for Computing Machinery
  Today's data centers may contain tens of thousands of computers with significant aggregate bandwidth requirements. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP switches/routers, resulting topologies may only support 50% of the aggregate bandwidth available at the edge of the network, while still incurring tremendous cost. Non-uniform bandwidth among data center nodes complicates application design and limits overall system performance. This paper shows how to leverage largely commodity Ethernet switches to support the full aggregate bandwidth of clusters consisting of tens of thousands of elements.

whitepaper Latency Equalization: A Programmable Routing Service Primitive2008-08-22 Association for Computing Machinery
  Today the Internet is the primary medium for deploying new real time services such as gaming and distributed online live music concerts. Different network services have different expectations from the routing infrastructure. Some network services require conventional routing paths optimized for low latency or low congestion. However, real-time interactive services such as online gaming and distributed live music performance require more than just low latency. They require Latency EQualization (LEQ) among participating users. Although LEQ could be performed by the client or the server, end-system techniques for estimating network conditions are often inaccurate. Instead, the paper argues that the network should provide a LEQ service. It proposes a LEQ routing architecture that can leverage programmable hub nodes.   
whitepaper Performance Evaluation for Remote Access VPNs on Windows Server 20032008-08-12 Institute of Electrical and Electronics Engineers
  A Virtual Private Network (VPN) can be defined as a way to provide secure communication between members of a group through use of the public telecommunication infrastructure, maintaining privacy through the use of a tunneling protocol and security procedures. This work examines and empirically evaluates the remote access VPNs, namely Point to Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol over Internet Protocol Security (L2TP/IPSec), and Secure Socket Layer (SSL). The paper explores the impact of these VPNs on end-to-end user application performance using metrics such as throughput, RTT, jitter, and packet loss. All experiments were conducted using wired and wireless windows XP SP/2 host (VPN Client) connected to a windows server 2003 host (VPN Server).

whitepaper Ethernet: The High Bandwidth Low-Latency Data Center Switching Fabric2008-08-08 Force10 Networks
  The transition to 10 GbE is under way in the data center, and the ubiquity and reliability of Ethernet make it a desirable solution for delivering a high performance data center network, storage and compute fabric. Ethernet technology has reached a maturity and is a compelling proposition. The mass-market availability of 10 GbE adapters and switches enables Ethernet based networks to deliver high bandwidth, high throughput and low latency solutions for the rigorous demands of data center applications.

whitepaper Foundry Helps EEC Deploy Internal and External Network2008-08-01 Foundry Networks
  Located at Microsoft's corporate campus in Redmond, Washington, the Enterprise Engineering Center (EEC) is a state-of-the-art proving ground for the world's most complex computing environments. The EEC wanted to deploy a network that would give internal and external customers access to resources located within the EEC, as well as the labs connected to a new 10 Gigabit Campus Area Network (CAN). Microsoft's Enterprise Engineering Center selected Foundry Networks NetIron MLX-16 router for its core, as well as two NetIron MLX-4 routers in other labs to allow for VPLS across a 10 Gigabit connection.

whitepaper Juniper Networks Enables Secure Remote Access for the Thai Technology Institute2008-08-01 Juniper Networks
  As the number of users grew, the King Mongkut's Institute of Technology Lakdrabang (KMITL) network was challenged to provide secure remote connections for users accessing the campus network. The Computer Research and Service Center (CRSC) considered implementing a VPN, yet software had to be installed on every client computer, which made the system complicated and difficult to use. To avoid this, the CRSC decided to go with the Web version of a VPN-an SSL VPN solution-since most of the users would have a Web browser. KMITL deployed solution from Juniper Networks which comprises four components: the Juniper Networks Secure Access 2000 (SA 2000) SSL VPN, the J-series Services Routers J2350 and J6350, the ISG 2000, and SSG 550M.
