About the IP Data Application
The basic capability of the IP Data test application provides nodal test capability for a content-based billing device, content filtering device, or any device that performs packet inspection. Bearer plane traffic is generated by the test system and routed through the device using an IPv4 or IPv6 transport. The optional features for this application, explained below, allow you to add RADIUS to an IP test or to test WLAN access to a UMTS network via a Packet Data Gateway (PDG).
When describing IP Data testing, the following terminology is used:
-
Mobile Node (MN) or Client Node — The mobile unit.
-
Network Host — An application server with which the mobile node can exchange bearer plane traffic.
-
Content Gateway — The SUT through which bearer plane traffic is routed. A Content Gateway performs some level of packet inspection on the traffic traversing it.
The IP Application Node and Network Host test cases are provided with IP Data, and work together to simulate the MN clients (IP Application Node) and an application server (Network Host).
The test system simulates the MN clients from the standpoint of generating unique source IP addresses and generating data traffic towards the Network Host. The Network Host listens for and responds to client requests. Static routes defined on the test servers route the messages exchanged between the MNs and the Network Host through the Content Gateway. DHCP client support is also provided, enabling the Client Nodes to obtain IP addresses from a DHCP server. With the optional Dynamic IPSec feature, you can encrypt the data traffic.
If you have also purchased the AAA RADIUS test application, you can add the functionality of the AAA Server Nodal test case to the IP Application Node.
With the AAA option, the test system simulates a Network Access Server (NAS) that generates RADIUS authentication and accounting messages towards AAA servers. IP addresses for the MN clients can be obtained from a AAA server during authentication, and those addresses will be assigned to the clients and used as the source addresses for the data packets generated by the clients.
The optional PDG Testing feature adds the PDG Micro-Mobility test case to the application. With it, you can test wireless access to a UMTS network and services from a WLAN.
The test system simulates the MNs and a Network Host. The MNs establish IPSec SAs with the PDG using MOBIKE and EAP authentication. You can test the Packet Data Gateway's capability to correctly control WLAN access to UMTS services along with its ability to maintain IPSec tunnels while the MNs move between WLAN addresses (micro-mobility).
