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 Cisco IOS Embedded Event Manager Version 2.4 Expanded Capabilities and New Interfaces2008-08-01 Cisco Systems
  Cisco IOS Embedded Event Manager (EEM) is a powerful tool integrated with Cisco IOS Software for monitoring and management from within the device itself. EEM offers the ability to monitor software subsystems and take informational, corrective, or any desired action when the monitored events occur or when a threshold is reached. Capturing the state of the router during such situations can be invaluable in taking immediate recovery actions and gathering information to perform root-cause analysis. Network availability is also improved if automatic recovery actions are performed without the need to fully reboot the routing device.

whitepaper Layer 2 Extension Between Remote Data Centers - Cisco Catalyst 6500 Series Virtual Switching System and L2VPNoGRE2008-08-01 Cisco Systems
  Cisco recommends retaining Layer 2 domains within each data center. However to meet new application framework requirements or for migration purposes, the Enterprise may have to extend Layer 2 beyond the Data Center. If there is no Layer 3 alternative, Cisco recommends the three approaches below. These approaches allow the safeguarding of sturdy extended Layer 2 networks while maintaining multipath redundancy with fast convergences and high performance. All of these solutions are executed in hardware and enterprises can deploy different Classes of Service by application.
