Corporate WAN

A WAN is an excellent way for companies to utilize geographically remote resources and centralize productivity. WAN allows employees, field personal, and management full or restricted access to pertinent data twenty-four hours a day, seven days a week.

Multiprotocol Label Switching Virtual Private Network

To achieve the security that is required for corporate users, virtual private networks (VPNs) can be used to guarantee that traffic is securely tunneled over the network. Up to now, most VPNs have been provisioned using Layer 2 technologies, such as Frame Relay and asynchronous transfer mode (ATM). These technologies provided secure tunnels, were resistant to Denial-of-Service (DoS) and intrusion attacks, and provided address and routing separation. The problem with Layer 2 VPN technology is that it does not scale well. As the network grows, the number of required virtual circuits achieving optimal routing scales non-linearly. It is also difficult to provide traffic engineering using a Layer 2 VPN approach.

To solve these scaling problems, a border gateway protocol/multiprotocol label switching (BGP/MPLS) VPN standard is now being adopted to provide Layer 3 VPN solutions using BGP to carry route information over a MPLS core. This Layer 3 MPLS-VPN solution achieves all of the security of the Layer 2 approach, while adding enhanced scalability inherent in the use of Layer 3 routing technology
