http://www.cisco.com/warp/public/784/packet/july98/6.html Technically Speaking: Policy-Based Networking in IP Virtual Private Networks By Rob Redford, Director of Product Marketing, Cisco Systems WAN Business Unit If you're managing a fast-growing intranet or planning an extranet, you've probably considered building a virtual private network (VPN) for IP services that uses the Internet or a service provider's private backbone, instead of expensive, less flexible private lines. For most network managers, I believe it's not a question of whether you'll implement that VPN or not, it's simply a question of when. To save money and hassle, many companies setting up VPNs today will decide to outsource some or all of the job to a service provider. But sharing the responsibility for your VPN presents a new challenge. How will you retain control over your company's mission-critical data when the portion of the data-handling network that's owned and operated by your service provider becomes larger? The answer lies in policy-based networking, an emerging capability that ultimately will give you the same control over your service provider's network that the CiscoAssure Policy Networking initiative gives you over your own. The start of this trend can be seen today in dialup IP-based VPNs that let subscribers control their own security policies with a CiscoAssure server.
