Do some Internet research to identify some of the major vendors of MPLS service providers. The Web site www.mplsprovider.com/mpls-service-provider.asp may be helpful in your search for information. Focus on three or four vendors that you think do a particularly good job describing the business benefits of MPLS to potential subscribers and explain why you are particularly impressed by these providers. If you were in charge and had to select the MPLS service vendor for your business, which would you choose? Why?
