What is DLNA Testing? Austin Pond

What is DLNA testing? DLNA Testing entails many different forms of testing, all of which are necessary for certification: Pre-Testing, MCVT, CTT, Interoperability, Auto-IP/Small Network, and possibly LPTT. These tests must all pass for all device classes to properly ensure DLNA protocol compliance and interoperability.

1000-T Jitter Test Channel Jon Beckwith

Subclause 40.6.1.1.1 of the IEEE 802.3 Standard defines a test channel to be used in the testing of the jitter on the reference clock of 1000BASE-T devices. The channel consists of two short segments of 120m UTP Category 5 compliant cable, along with one (or two, if necessary) long (the exact length is dependent upon the attenuation of the entire channel) segment of 100m UTP Category 5 compliant cable. The channel is to meet or exceed the insertion loss, crosstalk, and return loss requirements as specified in clause 40.7. The objective of this paper is to outline and describe, in detail, the specifications defined in subclause 40.6.1.1.1 of the IEEE 802.3-2002 standard for the Jitter Test Channel, and observe the results of the testing of a completed test channel. Included are plots, outlining the characteristics of the constructed test channel, along with the limits of each specific test.

RSP: Development of an 802.11 MAC Richard L. Lynch

In the growing world of ubiquitous networking, people often take for granted that interoperability exists between their network devices and the networks they are connecting to. Consortium vendors and international standards bodies are formed to establish standards on how devices should behave if they wish to communicate with each other. However, verifying conformance to these standards is no trivial task. The RSP was developed to add to the Wireless LAN Consortium's testing capabilities. The RSP has the capability of reacting to wireless traffic in a manner that tests a device's handling of uncommon, but very important conditions. The RSP Consists of an 802.11 MAC'less card from Intersil, interfaced to an Altera programmable logic device, which in turn communicates with a PC through a USB microcontroller.
