Release 3.5.1 previews the AAA Diameter application and the AAA Diameter Server node. General test system enhancements and enhancements to existing applications and features that are included in Release 3.5.1 are listed in the first section. See the second section for Release 3.5 changes.
When you provision attributes with a Test Data File, you can now configure a variable number of VSAs for each MN by supplying blank values for attributes that should not be assigned.
The Mobile IP VPN access model is now supported in the FA Nodal and HA Nodal test cases with MIP IPSec.
Measurements for the CGF Node test case have been re-arranged into the Billing, GTP', and GTP' Node report tabs.
When two or more DMFs are assigned to different Network Hosts, each DMF can now use the same Client Port and Server Port. A validation error will occur if duplicate ports are used in DMFs that are assigned to the same Network Host.
You can now configure the Retry Interval for IKE messages that require a response.
IKEv2 error notifications have been added to IPSec measurements.
IPSec packet measurements have been expanded to include IKE messages sent and received and SSL block encryption/decryption.
When you reconnect to a test session, measurements will be reported in timed intervals rather than in one Current interval. The timing of the intervals may vary slightly depending on the length of the test, but will synchronize when you click the Load History button.
Set or clear the Follow-on bit in Attach Request messages with the Follow On checkbox.
The Operator Variant Algorithm Configuration Field has been added to the Authentication pane on the GMM sub-tab.
An Authentication Failed measurement has been added to the GMM report tab.
The Geographic Area IE is now supported for RANAP Location Reporting.
When a GGSN is emulated, the destination port in messages sent by the node will match the source port in messages received from the SGSN SUT by default.
The size of the fixed authentication value has been increased to 16 bytes.
Release 3.5 introduces the CGF Emulation and GGSN G-CDR Validation features. General test system enhancements and enhancements to existing applications and features that are included in Release 3.5 are listed below.
You can provision incrementing parameters and VSAs in both AAA test cases with non-sequential values through the use of Test Data Files.
The default Wait Acct-Start-Msg Time in the AAA Server Node test case has been increased to 20 seconds.
All SUT parameters have been moved to the NAS tab in the AAA Server Nodal test case, and the method for defining a AAA Pool has been improved.
You can now use text, graphic, and multimedia files as Filler Data in DMF messages. Import the files into your system with the Test Data Files window.
The Basic Data throughput calculator now analyzes the Transaction Rate and will suggest a rate that conforms with the transaction timer granularity.
You can create a new DMF from an imported message trace.
New measurements have been added to the Network Host tab to record one-way latency between the MN and the Network Host for both Basic Data and Advanced Data message flows.
The number of user-defined events available in Message Flow Controls has been increased to 10.
Convert a DMF that could be used as a subflow to a DMF that can contain a subflow with the Allow button in the Subflow pane of the Data Message Flow window.
IPSec NAT Traversal (NAT-T) is now supported for both bearer plane and control plane IPSec.
Secondary PDP context activation can be delayed until required by a DMF. New Message Flow Controls have been added that allow you to trigger secondary context activation and pause DMF execution until the context has been activated.
You can now specify next-hop routing for MNs when an FA node is not used in the IPv4 HA Nodal test case.
Periodically save a Test Report during a long-duration test with the new Auto-Saved Report option.
A query command has been added to the API test commands, which allows you to sample up to 3 measurement values while a test is running.
The following parameters have been added to support GPRS Release 6:
UMTS Version allows you to test with either Release 4 or Release 6.
Enable Early RAB Assignment during Routing Area Updates with a new checkbox in the RANAP settings.
Specify the timing and destination for RIM Messages in the RANAP settings.
High Speed Downlink Packet Access (HSDPA) attributes have been added to QOS parameters.
PDP context modifications initiated by the Core Network are supported.
Sets of Access Point Names can now be configured and assigned to PDP contexts in round-robin mode. A retry capability has also been added that can cycle through the set of APNs until a primary PDP context has been successfully activated.
Multiple Location Area Codes and Routing Area Codes can be defined and distributed among MNs. Location Area Code was removed from the GMM tab.
IPv6 addresses are now supported for PDP contexts.
Unrecognized GTP Padding Bytes Received has been added to GTP and SM measurements to record the number of invalid padding bytes received in GTP-U packets.
New GMM measurements have been added for the Service Request procedure and Routing Area Update timeout.
