In a previous article we looked at how to mathematically calculate the reliability of electronic equipment. That is, the probability of it working correctly for a given period of time. This is best characterised by the Mean Time Between Failure (MTBF), or its opposite, Failure In Time (FIT). MTBF values are often in the order of hundreds of thousands of hours for electronic equipment. Source:...
We’ve all heard the phrase that timing is everything. Nowadays, the buses that connect, for example, processors to main memory require very precise timing, in the order of tenths of nanoseconds. Manufacturers provide all this information in their datasheets, but it needs to be combined with the appropriate Input/output Buffer Information Specification (IBIS) models and PCB (printed circuit...
Traditionally several current network scenarios are based on packet routing, but to reduce the network complexity, a concept has appeared on the market: session-based routing. This is due to theThe evolution of the network, which has reached a point where the complexity is continuously growing, and the elements involved are more and more expensive. A session is not a new concept, because many of...
The concept of code coverage affects any existing software application, from PC programs, mobile apps, the latest application for your SmartTV or router firmware. While it’s not a concept that depends on whether the software is connected to the Internet, it does affect us all. Let’s explain what it is and how to deal with it. Broadly speaking, one could consider that a software lifecycle project...
By now IP devices are already more than just a fancy hype. The Internet of Things (IoT) will connect about 5 billion terminals and devices this year, with a rising tendency - in 2020 about 25 billion intelligent objects are expected to be connected to the Internet, about three times more than the world’s current population. For end users as well as for business clients, IP devices such as smart...
The performance, power, energy consumption and useful life of routers are all measurable factors in product testing. The data, however, depend on the conditions under which manufacturers carry out the tests. Transparency is vital! After 10 years and more than 400,000 km, it is finally time to say goodbye to my little Citroen Xsara. Who brought up planned obsolescence? It is with a degree of...
