Abstract

In order to enhance the interoperability of roaming and tunneling services, it is desirable to have a standardized method for identifying users. This document proposes syntax for the Network Access Identifier (NAI), the userID submitted by the client during PPP authentication. It is expected that this will be of interest for support of roaming as well as tunneling. "Roaming capability" may be loosely defined as the ability to use any one of multiple Internet service providers (ISPs), while maintaining a formal, customer-vendor relationship with only one. Examples of where roaming capabilities might be required include ISP "confederations" and ISP-provided corporate network access support.
