Don’t Drown in the Registration Flood

New application note introduces strategies to prevent outages due to registration flood
Registration traffic was once an afterthought in designing VoIP networks. But today’s network registration messages generate an overwhelming amount of network traffic. As a result, poorly designed and tested networks can succumb to outages caused by the dreaded registration flood.
This new Empirix application note reviews registration in SIP and IMS networks, describes what occurs during a registration flood, and introduces testing and monitoring strategies for preventing these outages.
 Read the complete application note.

Testing for IMS Interoperability
IMS (IP Multimedia Subsystem) strategies now underpin many of the world's Tier 1 carrier next-generation network strategies, but with IMS standards so new, recognized interoperability and test methodologies are just emerging. This Webcast explores some of the initial test initiatives vendors and carriers should adopt as they put IMS elements, such as the Application Server (AS), Home Subscriber Server (HSS), and Policy Decision Function (PDF), through their paces in the lab.

Ensuring a Quality IMS Experience
While the initial hype behind IMS may have died down, quality assurance activity for the architecture has increased exponentially. Testing and monitoring of IMS is more important than ever and today’s telecom quality engineers have a lot of work ahead.
This webcast provides an overview on how to ensure a quality IMS experience, specifically it covers:
- The latest telecom quality assurance processes and how they must adapt for IMS
- IMS device testing examples including test setup, common problem areas, and key success metrics
- Testing and monitoring common real-world end-to-end IMS network problems
- Ensuring quality in IMS applications such as Hosted Business VoIP services, Push-to-Talk over Cellular, and FMC
- Best practices for testing and monitoring IMS

Voice Quality in an FMC Environment
A webcast presented by the V2oIP Quality Alliance
Experiencing better-than-PSTN voice quality is a reality, but not always simple to deliver. Furthermore, a fixed / mobile converged network adds additional complexity due to mobility, handoffs and new handsets. View this webcast to learn more. Although new VoIP technology offers cost and feature advantages for both enterprises and consumers, exceptional voice quality is critical for VoIP to ultimately succeed. Experiencing better-than-PSTN voice quality is a reality, but not always simple to deliver. Furthermore, a fixed / mobile converged network adds additional complexity due to mobility, handoffs and new handsets.
FMC offers the promise of IP combined with the flexibility of mobility. This webcast examines voice quality issues critical to the ultimate success of VoIP as well as the impact of voice quality on FMC.

Tips & Tricks
|
Running Hammer NXT-IP and Hammer Call Analyzer on The Same Machine
The Hammer Call Analyzer (HCA) is a useful tool for debugging test problems. Now the HCA can be configured to run on the same machine as the Hammer NXT-IP for viewing signaling traffic, thereby eliminating the need to setup taps or mirror ports:
- Take the custom npf.sys driver delivered with NXT-IP and save it. This is in C:\Windows\System32\Drivers\npf.sys. Save it as C:\Hammer\temp\npf.sys.save.
- Install the Hammer Call Analyzer with winpcap 3.0.
- Make sure custom NXT-IP version of the npf.sys driver is in C:\Windows\System32\Drivers.
- Take the one saved off in Step #1 and place it back into the \Drivers folder.
Hammer NXT-IP and HCA should now work together properly. A mirror port or tap is still required to view media traffic.
Configuring ODBC / Microsoft Access Database to be Used with Hammer FX-IP or Hammer FX-TDM
With Hammer FX, you can use an ODBC data source to access and modify data in a database. An ODBC connection establishes a link between a custom database, the ODBC drivers, and your application. Hammer FX supports any relational data source, such as Sybase SQL Anywhere, Microsoft Access, Microsoft Excel, and Oracle. You use standard SQL query statements for any data source type. Hammer FX includes a set of HVB functions that read or write to a custom ODBC data source. See the ODBC Functions topic in Testbuilder online Help for more information.
To set-up a DSN connection to your ODBC database (this example uses a Microsoft Access database):
- Navigate to Control Panel -> Administrator Tools -> ODBC
- Click “Add”.
- In the "Create New Data Source" dialog, select "Microsoft Access Driver (*.mdb). Click “Finish”. [Note: if you are using another type of relational database, select the driver corresponding to your database application.]
- In the "Data Source Name" dialog, name your DSN connection – make sure your connection name is unique. For "Database", browse to your access database. Click “OK”.
- To verify that the data source is created, use "regedt32" from the command line to launch the registry viewer. Then, navigate to the following location in the Windows registry - you will see an entry for your ODBC connection: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI.
For help with using a database on a remote system, refer to article #188 in the Empirix Knowledge Base, How to access a remote MS Access database using HVB script from an FX-TDM on Win2k3 Server.
