The Landslide Performance Test System uniquely enables network providers the ability to test all of their elements in an end-to-end configuration, using real-world control and data traffic models. Network equipment manufacturers can use the Landslide to improve and validate their products by simulating complex scenarios and customer environments.
Landslide is the only performance test tool available that combines all of the key wireless control signaling with a broad range of bearer plane data applications on a single platform. Using the Landslide , you can test individual network elements or the end-to-end network while emulating complex scenarios of millions of mobile nodes simultaneously activating and deactivating sessions, moving between network elements, and accessing various data services.
The Landslide was specifically designed to emulate complex, real-world traffic models through the combination of control plane and bearer plane testing in parallel. Using the Landslide’s ability to configure test sessions with multiple data applications and a variety of control traffic, you can quickly re-create the most complex traffic models, and determine how each network element will function in the live network.
The Landslide performance test system provides applications that focus on specific wireless technologies or network elements. These applications may be used as stand alone applications or co-resident applications on the same platforms.

Additional features can be added to the system to enhance the test applications.
AAA Diameter Server Emulation allows you to add a virtual Diameter NASREQ server to a CDMA2000, GPRS, or Mobile IP test. The virtual server provides the NASREQ authentication and accounting services required for the network configuration and can allocate IP addresses to the emulated mobile nodes. You can also use the virtual server to support test operations performed by other test systems or tools.
AAA RADIUS Server Emulation allows you to add a virtual AAA RADIUS server to a CDMA2000, GPRS, or Mobile IP test. The virtual server provides the RADIUS authentication and accounting services required for the test and can allocate IP addresses to the emulated mobile nodes. You can also use the virtual server to support test operations performed by other test systems or tools.
The Advanced Data feature provides the CDMA2000, GPRS, or Mobile IP applications with complex data types and the ability to build and save your own data messages and transactions, and combine message and transactions into data flows.
The CGF Emulation feature provides a virtual Charging Gateway Function for GPRS or UMTS testing. The virtual CGF can simply respond to GTP' messages received, collect CDRs received from the GSNs involved in the test, or validate the timeliness of partial G-CDRs.
Data and Performance Accelerator feature increases the Test Server capacity, data, and performance throughput. These features are enabled when you reserve ports to run your test session.
DCCA Server Emulation allows you to add a virtual DCCA server to your GPRS or UMTS test. The virtual server supports session-based Credit Control, and can introduce errors to test the DCCA client's compliance.
DHCP Server Emulation allows you to add a virtual DHCP server to a GPRS test. The virtual server provides simple DHCP IP address allocation services to a GGSN that acts as a DHCP client or Relay Agent.
The Dynamic IPSec feature provides IPSec encryption of Data Traffic for data-capable applications, and provides control plane IPSec support for CDMA2000 and AAA Diameter testing.
The External Data Sourcing feature allows the CDMA2000, GPRS, or Mobile IP applications to use an external network host in the data traffic stream.
Gb/IP Support adds 2G-SGSN Gb interface testing capability to the GPRS and UMTS applications through the UMTS test case.
The GGSN Emulation feature provides a virtual GGSN that can be used to support test operations performed by other test systems or tools.
The GGSN G-CDR Validation feature, when used with the CGF Emulation feature and the GPRS application, allows you to validate the accuracy of G-CDRs.
The GGSN Vendor-Specific Per-Flow CDR Validation feature, in conjunction with the CGF Emulation and GGSN G-CDR Validation features, extends G-CDR Validation to vendor-specific per-flow attributes.
The IMS Security Testing feature extends the Advanced Data feature by adding support for IMS AKA authentication to Data Message Flows.
The L2TP Network Server and L2TP Secure Network Server features provide a virtual LNS that can be used to support test operations performed by other test systems or tools. The Secure Network Server feature includes IPSec between the LNS node and LAC SUT.
The PDG Test Feature adds the PDG Micro-Mobility test case to the IP Data application to support nodal testing of a Packet Data Gateway.
The PDIF Test Feature adds the CDMA/Wifi Convergence test case to the Mobile IP application to support nodal or end-to-end testing of a Packet Data Interworking Function. When the test system is also licensed for the CDMA2000 application, you can simulate mobility between WiFi and CDMA2000 networks.
The Port Reservation feature allows you to reserve a specific port for exclusive use of a test session . The feature also provides the ability to run multiple IP addresses and sub-masks on the same physical interface. Using reserved ports as part of your test session also increases performance and data throughput by running tests across multiple threads/processes on a single Test Server.
The SGSN Billing Support feature, when used with the CGF Emulation feature and the UMTS application, allows you to validate the accuracy of S-CDRs.
The following features are included in all Landslide test systems:
Use the graphical interface to quickly set up and execute complex test sessions, monitor the test progress, and analyze the test results. Also, Tcl API support to automate your tests.
Define standard tests and save them in the Test Library to ensure repeatable results.
With the powerful Automation Control feature, you can run a set of tests in parallel or in a series, creating "real-world" scenarios for heavy load and long duration stability tests. Just as in a live network, the test system can generate variable connection rates and loads, mobility events, bearer traffic with application protocols, and error scenarios. Tests can be run continuously for up to 30 days.
Use the Test Session Scheduler to run pre-configured test sessions at a time of your choosing.
An API is provided, which allows you to execute and control a test session from a master test script on another device.
The Test Server Reservation Scheduler can be used to reserve a block of time on a server for the exclusive use of one user. This feature can be used to prohibit test operations while maintenance is performed, or to dedicate a server to a particular test.
Monitor test progress and other system activity with real-time event logs. A graphic status window lets you see at a glance which users are on the system, what test sessions are executing, which servers are involved in testing, and the status of your servers.
View the test results in tabular reports that display interval measurements. The reports include all of the test results, and the operational measurements for each protocol layer. You can set the measurements to cumulative or interval values, and you can set the granularity of the report: the test session as a whole, individual tests performed by the session, or measurements for individual emulated mobile nodes. Export the test results in Excel or comma-separated value (csv) formats to perform detailed analysis, or retrieve the test results that are automatically saved when the test is complete.
The Wireshark Network Analyzer is packaged with the test system and can be used to capture packets sent and received during a test.
