2 Understanding the problem February 23,

3 MPLS what problem does it solve Reduce complexity in core network nodes Introduce flexible new routing services in the network New services or applications implemented in the edge without modifying the core Some of the new services that use MPLS Virtual private networks (VPN) many s securely over a shared core network Legacy transports over a common network Differentiated service levels Traffic engineering ability to direct where traffic goes February 23,

4 MPLS what problem does it create Provisioning can be complex Hard to map from network problems to the Network performance needs to be mapped to or service Differentiated class of service introduce the need to monitor service levels February 23,
