CDRouter release 10.6 - TR-143 diagnostics, custom profiles, and more

CDRouter 10.6 is now available! This release has some amazing new tests and features for TR-069 testing, IPv6, and Wireless WAN. TR-143 performance testing TR-069 includes a set of diagnostic tools defined and controlled through the TR-069 data model, originally outlined in Broadband Forum Technical Report 143 (TR-143), “Enabling Network Throughput Performance Tests and Statistical Monitoring”. Doing these tests requires triggering a CWMP endpoint to do things like download from an HTTP server, which also requires an HTTP server to be set up as part of your testing. Read more...

CDRouter release 10.5 - new wireless testing, ARP security, result comparison, and more

CDRouter 10.5 is now available! We’ve brought huge leaps in CDRouter’s wireless test capability, some critical tests for ARP vulnerabilities, and more: New wireless tests As Wifi becomes the technology of choice for the home network, the demands on Wifi APs and Wifi gateways are getting more nad more intense. We’ve added five new tests in our Wifi test module that flex a DUT’s handling of association, and that Wifi beacons are compliant with the standard. Read more...

Using CDRouter Through the Testing Lifecycle

Download this whitepaper (pdf) There’s no question that broadband is the premier service delivery platform of the 21st century. With the explosion of new devices now aware of the network, and new services looking to exploit them, the devices you produce or deploy are becoming more complex than ever before. This puts pressure on everyone in the supply chain, from chipset vendor to service provider, to ensure their devices are tested well at every stage of the testing lifecycle. Read more...

Building on RFC 2544

At QA Cafe we deal directly with a lot of standards from many different organizations, all of which go into making the home routers and other connected devices that we test with CDRouter. When it comes to performance testing, the most frequently cited standard is IETF RFC 2544, the “Benchmarking Methodology for Network Interconnect Devices”. Created in 1999, it is the methodology used by most router performance test tools in the market. Read more...

Testing Hurdles of Wifi APs and Wifi Mesh Nodes

The rapid expansion of Wifi as the medium of choice for home networking has introduced an explosion of new products from both new and established manufacturers. If you’re a developer or QA testing looking to prove your implementation works, or a service provider testing before deployment, you’ve probably learned that testing Wifi involves more than just physical and MAC layer performance and interoperability. What else should you test to ensure that your devices will work well in the real world? Read more...

What should you look for when testing broadband CPE or Wifi performance?

If you are developing or deploying broadband CPE, routers, or Wifi devices, what are the things you should look for when testing performance? Hint - it's more than just throughput, and having a fully automated system to exercise the entire system is key to ensuring true performance. What is performance testing? What do we mean when we talk about performance testing on a broadband gateway or access point? Read more...

CDRouter Release 10.4 - GRE, Application Latency, TR-069 Bootstrap, and more

CDRouter 10.4 is now available! With some major features and upgrades to performance, TR-069, and more, it’s a great time to upgrade your CDRouter system. Application Latency Performance Testing When it comes to performance testing, layer 2 throughput testing is what most tools stick to. But is it enough? No - “line rate” can only mean so much. CDRouter 10.4 introduces application specific latency test cases for DHCP, DNS, and ICMP, to help you exercise how your devices will actually behave from an end user’s perspective. Read more...

Understanding Performance Results

We get a lot of feedback from our users discovering new and interesting results when combining functional testing with throughput, latency, and loss testing. Having a good understanding of how performance tests work and the caveats around their results can help you determine how your functional tests are impacting performance, and visa-versa. Understanding the theoretical maximum of application data What is “line rate”? CDRouter Performance is designed to measure “application level” throughput. Read more...
