A Virtual Private Network (VPN) is a private communications network often used within a company, or by several companies or organizations, to communicate confidentially over a publicly accessible network. VPN message traffic can be carried over a public networking infrastructure (e.g. the Internet) on top of standard protocols.
Interconnecting three or more sites across a metro or wide area network has traditionally been accomplished via a hub and spoke network topology using Private Lines, Frame Relay or IP VPNs over the Internet. Ethernet services support hub and spoke topologies but also support an “any-to-any” network topology similar to a LAN but delivered over a wide area. This latter capability is unique to Ethernet services and cannot be cost effectively delivered using legacy point-to-point technologies such as Frame Relay or IP VPNs.
This paper discusses two options for multi-site connectivity using Ethernet services. One option discusses the classical hub and spoke topology using Ethernet Virtual Private Lines (EVPL). The other option discusses the “any-to-any” topology using an Ethernet Private LAN (EP-LAN) service. Through examples, the paper illustrates the capabilities of the two approaches and their benefits.
App and desktop virtualization is much more than a technology solution. It is transforming the way organizations of all sizes are enabling their workforces while simplifying the desktop management process for IT administrators. With app and desktop virtualization, IT organizations can provide every user with a workspace environment completely unrestricted by physical location.
This paper addresses many common business challenges facing IT organizations, such as enabling mobile workstyles without compromising security, streamlining desktop management efforts as the number of employees in remote offices and offshore locations increases and making the user experience personal through self-service access to applications and desktops.
This buyers guide is designed to help you choose the right solution for your organization. It looks at the factors you should consider when evaluating solutions to ensure you have the protection and functionality you need, both now and as your business evolves.
Most organizations today understand that a disaster recovery (DR) plan is essential to their continued survival should a natural disaster occur. But implementing a DR plan entails substantial time, effort and cost - not to mention significant investment in developing new areas of technical expertise within the organization. As a result, many organizations are turning to disaster recovery service providers (DRSPs) to offload their disaster recovery operations.
This report describes how improving the efficiency of data storage, deduplication solutions has enabled organizations to cost-justify the increased use of disk for backup and recovery. However, the changing demands on IT storage infrastructures have begun to strain the capabilities of initial deduplication products. To meet these demands, a new generation of deduplication solutions is emerging which scale easily, offer improved performance and availability and simplify management and integration within the IT storage infrastructure. HP refers to this new generation as "Deduplication 2.0.

The Cisco® Secure Network Foundation solution consists of switching, routing, and security devices in multiple validated and tested configurations. Highlighted in this solution profile are network configurations that range from the smallest networking need to full-function networks with integrated voice and video capability.
Previously, the network at the City of Lake Wales didn't possess any firewalls, intrusion protection or web filtering solutions. As a result the network, which is spread out to multiple locations (including law enforcement), was left wide open to security breaches and caused system performance problems as users unwittingly picked up spyware and malware.
Companies rely on knowledge assets, such as product formulas and customer databases. VPNs and network monitors can protect proprietary information from outsiders; but, they won't do much to prevent access by internal users. With the popularity of wireless networks, USB drives and other portable devices, it's all too easy for insiders to leak key data. This white paper explains how Trend Micro LeakProof 3.0 protects sensitive data at rest, in use, and in motion.
Whatever the size of your organization, a business-class network is within your reach. By understanding and taking some simple steps, you can implement a network infrastructure that provides your company with significant and substantive benefits. From empowering your employees to greatly improving customer service, networking technology can have a lasting impact on your business.
A wireless network can help your employees stay productive as they move around your company. But to take advantage of the benefits of wireless networking, you need to be sure that your network is safe from hackers and unauthorized users. Every device in a wireless network is important to security. Because a wireless LAN (WLAN) is a mobile network, you need a thorough, multilayered approach to safeguard traffic.
