Today businesses demand greater bandwidth and enhanced performance to meet their ever-increasing communications needs. Companies must be able to efficiently and cost-effectively communicate with geographically disbursed employees, remote workers, business partners, and suppliers.

IP Virtual Private Networks (IP VPNs) deliver the attributes of a private data network within a shared network infrastructure. They offer enterprise-class scalability and reach across multiple IP-based infrastructures, along with many of the performance and security characteristics traditionally found only in dedicated private environments.

IP VPNs play an important role in today's enterprises by providing the ability to deploy a cost-effective networking solution. IP VPNs offer flexible architectural options that harness the strength and reach of IP networks and provide simplified, secure, and scalable connectivity. Additionally, businesses can leverage their existing IP network infrastructure, thereby maximizing the return on investment and minimizing the total cost of ownership.

Applications for IP VPNs

Three basic applications drive enterprise-networking requirements today:

• Intranet - Allow users to gain access to secured corporate information
• Extranet - Support business-to-business communications
• Remote Access - Provide remote workers or traveling users the same level of connectivity as individuals who work in branch offices
