MPLS

Multiprotocol Label Switching (MPLS) VPN provides private transport over a SONET protected Internet Protocol (IP) backbone. Geographically diverse locations can communicate directly without the need for permanent circuits which may be costly and difficult to scale.

MPLS technology provides security and efficiency by switching IP packets based on a predetermined path instead of using traditional routing techniques. This provides an ideal platform to provide Quality of Service (QoS), ensuring that critical traffic like voice and video is prioritized over less time-sensitive applications like email and web surfing. MPLS VPN includes the following features and options:

• Four classes of service available as part of the QoS option
• Customers may choose Castlewire provided routers or use their existing equipment
• Supports static routes, Border Gateway Protocol, Enhanced Interior Gateway Protocol, and Open Shortest Path First
