Example 1: Simple IP Support Using a Single Source and
Destination Context
The most simple configuration that can be implemented on the system to support Simple IP data applications requires
that two contexts (one source and one destination) be configured on the system as shown below.
that two contexts (one source and one destination) be configured on the system as shown below.

The source context will facilitate the packet data serving node (PDSN) service(s) and the R-P and AAA interfaces. The
source context will also be configured to provide AAA functionality for subscriber sessions. The destination context
will facilitate the packet data network interface(s).
source context will also be configured to provide AAA functionality for subscriber sessions. The destination context
will facilitate the packet data network interface(s).
In this configuration, the wireless carrier provides the function of an Internet Service Provider (ISP) to their subscribers.
The PDSN service in the source context terminates subscriber point-to-point protocol (PPP) sessions and routes their
data traffic through the destination context to and from a packet data network such as the Internet.
