Network Management Strategies for the CIO
What is your take on MPLS and its effect/importance on VPNs and overall
corporate WAN efficiency/security?

MPLS offers a number of
benefits that enhance VPN, including scalability, performance, security, and efficiency. It
certainly bears careful consideration, particularly when building out new networks, for large-scale
deployments. The overall network performance picture includes support for IP-based services and
therefore continued progress toward data convergence, while maintaining most of the traditional
advantages of ATM and frame relay.
If the alternative to MPLS for broad deployment security is IPsec, then it should be an obvious choice - encryption is only a functional aspect of security, not a complete solution. Further, the apparent trend for corporate networks is toward "privatization" of networks in the general theme of the Infranet (as suggested by Juniper) – should this trend further develop, MPLS would likely be amongst the fundamental building blocks.
