UPnP compliance testing skyrockets

UPnP Forum has announced that as of the latest count, it has certified more than 900 devices as compliant with UPnP standards. About 700 are being publicly posted on the organization's website, indicating rapidly expanding home networks.

UPnP certification provides assurance to vendors and users that devices will automatically and seamlessly interoperate in home and other networks. In recent years the output of UPnP Forum has grown in line with the increase in the numbers and types of device being networked via the Internet. Since 2007, the Forum has seen double-digit percentage increases in the number of UPnP certifications, YoY. Compared to 2009, the organization last year certified three times as many devices that 'render' content, including TVs, speakers, audio players, electronic picture frames, PCs and printers. This year, it has certified 74 percent more renderer devices than in the whole of 2010.

To strengthen the confidence in UPnP technology, UPnP Forum recently introduced a new version of the UPnP certification test tool (UCTT 2.0) for compliance testing. This tool will extend the scope and relevance of the Forum's certification program.

"The main goal of the certification program is to demonstrate good interoperability between different vendors' devices, and the new certification tool increases the scope of our interoperability testing," stated Wouter van der Beek, UPnP compliance chair. "Furthermore, the toolUCTT 2.0enhances usability and test reporting, with extensive de-bug options able to provide more information to resolve any issues that arise."

"The build-from-scratch UCTT 2.0 is considerably stricter in validating UPnP communication between devices under test, supporting deeper test penetration and leading to more credible results. Consequently, the compliance assurance level is significantly higher and the certification much tougher to achieve, but potential IOP issues are detected and addressed all the way faster. Together with greatly improved ergonomics of the tool, all these lead to a new definition of user experience and enriched suitability of the tool for the whole certification process," added Grzegorz Kafel, UPnP specialist.

The entirely re-factored architecture of UCTT 2.0 makes it possible to certify both UPnP devices and control points within one tool. The active and run-time dynamic environment enables simulation of various UPnP network elements and on-the-fly analysis of intercommunication of both class devices, rather than post-processed parsing used by the previous version of the tool.

Flexibility and extensibility are important assets of UCTT 2.0, that allow licensees to develop specific test cases on their own, with no need to wait for the next release of the tool. Device specific actions of non-standard or custom UPnP prototypes can easily be defined in the open, XML-based and rich-syntax format, later to be incorporated into vendor-defined test suites and structured with the use of advanced testing logic introduced by the tool, noted UPnP.
