Mobile IP Test Cases
The test cases provided with the Mobile IP application allow you to test an FA, HA or a CN in a standalone (nodal) configuration, or an FA and HA in an end-to-end configuration. An FA can be tested in an IPv4 network, an HA can be tested in either an IPv4 or IPv6 network, and a CN can be tested in an IPv6 network. Bearer plane traffic can be added to any of the test cases.
With these test cases, you define:
-
The network environment and the specific access model
-
The session volume and rates, and an optional rate distribution model
-
Control protocol attributes and behaviors
Measurements collected for these test cases include:
-
Counters that record the number and types of messages sent and received
-
Average response times for the different types of messages received from an SUT
-
Errors encountered during the test
-
Session state and rates
Test Cases
Test Terminology
An MN session is the result of an MN successfully registering with an HA, with or without the involvement of an FA. The terms used for the various states that a session transitions through are defined as follows:
-
When the test begins, the test system reserves the resources necessary for the number of MN sessions defined (IP addresses and other unique identifiers, for example), and the MN side of the sessions are initiated and placed in the pending state.
-
A pending MN session is started with a registration request.
-
The session is connected and established with a successful registration reply.
-
If a session fails during or after establishment, and the retry failure rate reaches 100%, the session is left in the pending state.
-
An established session is disconnected with a request that originates from the MN.
-
If a session is disconnected as part of a test cycle and will be re-connected, the test system retains the session's resources for later use, and the session enters the pending state.
-
When the disconnect occurs at the end of the test, the test system releases the session's resources as part of the test clean up.
Test Options
When your test activity measures processing capability rather than rates, you can expand the scope of the test:
-
Add Data Traffic to the test to more closely simulate a live network using various wireless applications and protocols.
-
Encrypt Data Traffic with the optional Dynamic IPSec feature.
-
Use the SUT Query option to monitor the CPU utilization of an SUT, and determine the amount of activity that the SUT can handle within a given CPU threshold.
CDMA/WiFi Convergence
Test a PDIF-FA and optional HA in a WLAN access model. The test system emulates the MNs and can emulate an HA. IKEv2 with MOBIKE included for mobility support. The MNs initiate IPSec connections with the PDIF-FA and attempt to register with an HA. If your test system is also licensed for the CDMA2000 application, you can use the Inter-Technology Mobility and the Session Loading With Mobility test activities to simulate handoffs between WiFi and CDMA2000 networks.

Additional measurements may be available depending on the test activity and options executed with the test case.
CDMA/WiMAX Convergence
The CDMA/WiMAX Convergence test activities are used to simulate handoffs between WiMAX and CDMA2000 networks. The Inter Technology options are only available when you are licensed for both WiMAX and CDMA2000 applications. Valid MIP Scheme is CMIP for both Inter Technology Mobility and Session Loading With Mobility test configurations.
Emulators:
-
PCF Node
-
Base Station (R6) Node
-
SUTS - FA, ASN Gateway

IPv4 HA Nodal
Test an HA in any of the supported IPv4 access models. The test system emulates the MNs and can emulate FAs to provide mobility support. The MN or FA nodes generate control traffic towards the HA, and listen for and respond to messages from the HA.

IPv4 FA Nodal
Test an FA in any of the supported IPv4 access models. The test system emulates the MNs and can emulate HAs to provide mobility support. The MN or HA nodes generate control traffic towards the FA, and listen for and respond to messages from the FA.

IPv6 HA Nodal
Test an HA with any of the MN options provided. The test system emulates the MNs and a CN. Both can generate traffic towards the HA, and listen for and respond to messages from the HA.

IPv6 CN Nodal
Test a CN for Mobile IPv6 compliance by using Route Optimization with Data Traffic. The test system emulates the MNs and the routing functionality of an HA. The MNs generate traffic towards the CN, and listen for and respond to messages from the CN.

Additional measurements may be available depending on the test activity and options executed with the test case.
IPv6 CN Node
Simulate a CN in a separate test case that can be executed on a different test server than the IPv6 HA Nodal test case, doubling the Data Traffic capacity of the test. The CN acts as a Network Host and listens for and responds to Binding Update messages from the MNs when Route Optimization is used.
