TAKING ADVANTAGE OF CARRIER-OF-CARRIER CONNECTIONS | Robbie Harrell

SELLING AND EXPLAINING VPNS | Ed Tittel
Before anybody can grapple with the technical issues involved in choosing, implementing, and maintaining a VPN, one has to go through the exercise of explaining and selling the notion of virtual private networking to those who approve whatever investments of time, effort, and money are necessary to introduce and use this technology.
Fortunately, there is a lot of information available.
SRLGS SOLVE NETWORK RELIABILITY PROBLEMS | David Jacobs
Shared Risk Link Groups, SRLGs, increase the reliability of MPLS VPNs. Increased reliability is one of the advantages of MPLS over Frame Relay and ATM. Since MPLS is built on the IP networking foundation, it reroutes quickly on a failure. SRLGs guard against situations where even the reroute doesn't resolve the failure.
