That is the most cost-effective solution and the best way to use your bandwidth. You can stretch the given technology that is more cost-effective. Let's talk a little about the Internet. Some people say that because VPNs provide network services at lower costs via the public Internet, rather than via an expensive private network, they will become increasingly important. Corporations are geographically widespread.
Large corporations have private networks to deal with that problem.
Medium-sized companies and small companies have not had the luxury of doing that. But virtual private networks use the Internet backbone and allow companies to take advantage of the same capabilities and the same management of geographic dispersal that large companies have been able to get with private networks. That's what drove our interest in Shiva. Intel is interested in bringing the small and medium-sized companies into the Internet age. So far, our efforts have been mainly to help bring the different players in the industry together to agree on an implementable and effectively deployable standard for a universal DSL connection.
