I just published an I-D on VPN requirements. It may be of use to NANOG folk in helping determine what their customers want to do with a VPN, and/or explain to them about VPNs. I'm open either to making it more of a free-standing tutorial and requirmeents analysis guide, or merging it into an architecture RFC. Howard ------ A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Requirements Taxonomy for Virtual Private Networks Author(s) : H. Berkowitz Filename : draft-berkowitz-vpn-tax-00.txt Pages : 5 Date : 01-Mar-99 Proprietary definitions of virtual private networks proliferate in the marketplace, to the confusion of end users. This memorandum proposes a taxonomy which can describe a variety of VPN models. It does not recommend any specific model, but suggests a consistent way of describing specific VPNs. This document differs from some other working papers that go more deeply into the VPN mechanisms. In contrast, this document is focused on user requirments.
