Standard Test Capacity and Throughput

The maximum bearer traffic throughput varies according to the data protocol, the test application, and the number of UEs/subscribers emulated in the test. When the Network Host emulator and MS emulators share the same Landslide Test Server, bidirectional traffic for both the MSs and the Network Host are processed on one platform, effectively reducing the maximum throughput by one half. You can achieve the maximum throughput by using a separate platform for the Network Host. As the number of MSs increases, the processing required to manage the individually-timed data streams reduces the data throughput.

The following shows the available test sessions, supported default bearer per test session, and the number of default bearer or primary contexts supported in LTE test cases.

NOTES:

All Performance tests were run in normal mode (i.e., no Performance or Data acceleration).
Whenever you enable EAP, activation rates could be considerably lower.

Number of Test Sessions Available	Default Bearer per Test Session	Default Bearers or Primary contexts
150,000 Sessions	1 default Bearer per Test Session	150,000 Default Bearers or Primary contexts
300,000 Sessions	1 default Bearer per Test Session	300,000 Default Bearers or Primary contexts
600,000 Sessions	1 default Bearer per Test Session	600,000 Default Bearers or Primary contexts

NOTE: (Number of Sessions) * (Number of Default bearers per Session) <= maximum number of licensed sessions. For example:

For 150K licensed sessions: (150K sessions) / (2 Defaults/Session) = 75K sessions
For 600K licensed sessions: (600K sessions) / (4 Defaults/Session) = 150K sessions

Landslide C100 M4 systems support increased activation/deactivation rates (3000 activation/deactivations per second) during basic Capacity testing for the following test cases: MME Nodal, PGW Nodal, SGW Nodal, GGSN Nodal, OCS Node, OFCS Node, UMTS, HSS Node, MSC Node, PCRF Nodal, DCCA Nodal, AAA Nodal, and IP Application Node.

NOTEs:

The increased activation/deactivation rates may not be sustainable when running other than basic Capacity testing. In addition, the rate increase is not prevented nor supported on older Landslide platforms. In some cases, the older platforms may be able to establish sessions at a higher rate.
The C100 M4 may support increased activation rates for various applications. Contact support for the latest supported activation rates. Data not available at time of publication.

Test Server Data Performance

The data throughput and performance measurements for different Landslide releases show data gathered using a test methodology that achieves the maximum throughput — a Capacity test where in the data traffic starts after all connections have been established. These rates cannot be achieved when the test system is simultaneously processing control and bearer plane traffic.

NOTE: During HNB GW Nodal testing with mobility test activities, the session capacity is limited to half the licensed maximum.

NOTE: UMTS test case supports a maximum of 1000 BSS and 1094 NSEIs per BSS.

However, these two maximums are not supported at the same time. A combined maximum of BSSs and NSEIs (NSVCs) must be less than 20,480.

For example:

If you select 1094 NSEIs per BSS, the maximum supported BSSs = 20.
If you select 40 BSSs, then each BSS must can only support a maximum of 512 NSEIs.

During CDMA/WiFi Convergence testing, PDIF supports 200k sessions with an External HA, but when a Local HA is enabled, the maximum sessions drop to 195,000 sessions due to memory constraints.

NOTES:

An error occurs if the test session capacity, activation rate, or attach rate exceed the licensed value. For example, during PCRF Nodal and PCRF Node testing, an error occurs if the number of subscribers multiplied by the number of interfaces selected (AGW, AF, BBERF) results in more than the licensed maximum test sessions.
The supported number of sessions assumes that any node emulation is disabled. Adding node emulation or other features may decrease the number of sessions that the appliance can support.
