The second 2.5 release includes the changes listed in the first section below. This documentation also includes a preview of the L2TP Security Gateway Application that will be introduced in Release 3.0, instructions for using Data IPSec, and Data IPSec parameter definitions.
The AAA Server Nodal test case can now test up to 10 AAA servers in Round-Robin mode.
Release 2.5 introduces the IP Data Application, the Dynamic IPSec feature, and the DHCP Server Emulation feature. Enhancements to the AAA, CDMA2000, GPRS, and Mobile IP applications are listed below.
The new test features include per session and csv formatted reports, different ways that you can use test cases in test sessions, and second generation test cases with a re-designed user interface. Data Traffic enhancements include increased throughput performance utilizing a second on-board processor, two new FTP Data Message Flows, finer control of TCP control and data messaging, and individual delay times for DMF messages.
General system management and user interface enhancements include custom libraries, access to Wireshark from the Test Session window, customized alerts, and context-sensitive Help.
Second generation test cases are configured using the new Test Case Settings window. The user interface has been re-designed to more clearly group related parameters and improve the visibility of all options. In this release, the GPRS, CDMA2000, Network Host, and SUT Query test cases have been upgraded to second generation test cases.
While the transition from first generation to second generation test cases is under way, parameter topics that pertain to more than one test case — Data Traffic, for example — will be separated into two topics and a "(1st Gen)" or "(2nd Gen)" label appended to the Table of Contents title. If you search on a parameter name, the results will include both topics.
Test cases can now be saved in the Test Case Library and linked to by a test session. You can link multiple test sessions to the same test case and update all of the sessions by modifying the linked test case. You also have the option to save the test case locally with the test session rather than linking to a test case in the library. See Using Test Cases for more information.
When you upgrade to Release 2.5, test cases contained in saved test sessions are converted to local test cases with the same name as the derived test case.
The AAA Server Node test case now supports IP address allocation, and instructions for configuring the test case have been added in Setting Up a AAA Server Node. Test case parameters have also been simplified and re-arranged.
User Name can be provisioned with incrementing IP addresses and Password accepts null values and supports incrementing values in both the AAA Server Nodal and AAA Server Node test cases. See User Credentials.
DMU support is now available in the End-to-End Mobile IP test case.
Dynamic Home Agent address resolution is now supported in the End-to-End Mobile IP and FA Nodal test cases.
PCF, FA and HA emulators can simulate packet loss.
MIP authentication secrets, DMU secrets, and PPP Password now support incrementing values.
The ESN field can be explicitly included or excluded in Open RP messages with the Include ESN drop-down list.
The number of slots used for Van Jacobson compression can be defined.
Configurable fragmentation at the PPP layer has been added with the Local MTU parameter.
Several parameters have been added for finer control of L2TP testing: Maximum Retry Interval, Receive Window Size, and tunnel authentication.
A new measurement has been added to the MIP Revocation test activity: Sessions Not Ready For Revocation.
The IP Data application generates bearer plane traffic to test content-based billing devices, or any device that inspects data packets, without the involvement of controlling network elements or protocols.
If you purchased the DHCP Server Emulation feature, you can use the DHCP Server Node test case as a virtual DHCP server in a test session. The virtual server provides simple IP address allocation services to any client or relay agent that directs requests towards it.
If you purchased the Dynamic IPSec feature, you can encrypt Data Traffic in the End-to-End Mobile IP, GGSN Nodal, HA Nodal, IP Application Node, or Simple IP test cases. IPSec tunnels are established when MN sessions are activated and torn down when MN sessions are deactivated. Dynamic IPSec is included with the Mobile IP test application, providing MIPv6 IPSec capability in the IPv6 HA Nodal test case.
DHCP Client support for IPv4 and IPv6 is now available.
Data Message Flows can be executed on separate PDP contexts (mandatory with secondary PDP contexts) and QOS Profiles can be individually defined for each PDP context.
The QOS Update test activity now supports GTP-V1 and GTP-V0 QOS attributes and provides the ability to configure the test with a repeating update cycle.
The Inter-SGSN and Session Loading With Mobility test activities now support alternate QOS Profiles for the handoff PDP contexts that are defined on the Handoff GTP tab.
SGSN emulators can simulate packet loss.
IPv6 has been added to Payload Data Protocol options.
Octets 14 — 16 can optionally be included in the GTP-V1 QOS attributes.
Mobile Country Code and Mobile Network Code accept and retain leading zeros (see RAI Attributes and User Location Information).
The number of slots used for Van Jacobson compression can be defined.
Configurable fragmentation at the PPP layer has been added with the Local MTU parameter, and PPP Password now supports incrementing values.
A new IPv4 Mobile IP test case has been added, which can be used in either an FA nodal or end-to-end configuration.
A co-located care-of address can be used in conjunction with an emulated FA in the IPv4 HA Nodal test case.
Dynamic Home Agent address resolution is now supported in the IPv4 Mobile IP and IPv4 HA Nodal test cases.
MIP authentication secrets and PPP Password now support incrementing values.
Defined SUTs are now supported in the IPv6 HA Nodal and IPv6 CN Nodal test cases, enabling support for the SUT Query option and the use of an anycast address in Home Agent Discovery.
Enable Route Optimization has been moved from the Mobile Node tab to the Data Traffic tab in the IPv6 HA Nodal and IPv6 CN Nodal test cases.
New MN measurements have been added to the IPv6 HA Nodal and IPv6 CN Nodal test cases to record timeouts and retries for IPv6 control messages.
Data performance metrics have been added to Capacity and Throughput.
Several parameters have been added to provide increased control of TCP: you can define the TCP window size, a 3-way handshake can be mandatory when running application layer protocols over TCP, and TCP retry time can be configured whenever TCP is used.
When TCP packets are received out of sequence, a test server can queue up to 30MB of the remaining packets in the TCP window and process those packets as gaps in the sequence are filled.
Random port numbers can be used for the Client Port with any protocol, and can be used for the Server Port in the FTP Data Transfer Subflow.
When a remote Network Host is used, the same DMF used by the MN clients can be used by the remote host. It is no longer necessary to swap the Client Port and Server Port in the DMF used by the Network Host.
A new option has been added to remote Network Hosts. Reset Idle Host Traffic Session releases data resources when an MN is not responding.
Two new Advanced Data message flows are available. FTP Mainflow Active PORT Command and FTP Mainflow Active EPORT Command generate IPv4 and IPv6 active FTP transactions.
A Stop on Error checkbox has been added to DMF parameters.
A Send Delay time can be applied to individual messages in a DMF.
Valid Segment Size values have been changed to 128 — 65535.
The maximum Packet Size for Basic Data protocols has been increased to 65535.
External Data Sourcing measurements have been added to Data Traffic measurements.
Per Session Reports, which report measurements by MN session, are now available, Test Reports can be exported in either Excel or csv formats, and options have been added that allow you to customize a captured or Auto-Saved report. See About Test Reports, Report Formats, Capturing Reports, and Customizing Auto-Saved Reports for more information.
Switch report views between Summary and test case reports with a single click.
Graphs now use a separate vertical axis for each measurement.
The Wireshark Network Analyzer is included on each test server and can be used to capture packets sent and received by a test server during a test.
Expand the Test Library by adding custom libraries with restricted or global write permissions.
Synchronize the TAS with its NTP server and view NTP status with the TAS Manager Console.
Static routes can now be defined for IPv6.
The applet keeps the connection to the TAS alive while the user is idle and the connection state is displayed in the status bar.
The Client Memory Monitor provides the current plug-in memory consumption.
The maximum number of Automation Control steps has been increased to 300.
A confirmation message is displayed when you stop or abort an active test session.
The new Client Settings window allows you to define default directories and to choose which confirmation messages should be displayed.
Context Help is available for the main applet windows. Press F1 from a window to display the Help topic for that window. You can also use Control-F1 to override a pop-up blocker when Control is defined as the blocker's override key.
You can now simultaneously edit multiple test cases in the same test session.
When a test system is licensed for an evaluation period, you will receive a reminder that the license will expire when you log in to the system during the last 7 days of the evaluation period.
