TTCN-3 for distributed testing embedded software

A blade grinding mechanism for a razor consists of a razor dock, at least two razor blades located in the razor dock, and two grinding means located respectively below each of the razor blades in the razor dock. The grinding means has a grinding surface corresponding to the blade edge of the razor blade. After the razor has been used for shaving beards, both of the grinding means can be used to clear the residual beard debris, and be moved to the left and right side to grind and sharpen the blade edge of the razor blade.

Introduction of TTCN-3 into the product development process: considerations from an electronic devices developer point of view

Following the successful standardisation of TTCN-3, several attempts were made to introduce the language into the product development process to improve the related testing activities. For several years appreciation was moderate. Reasons are to be found in the structure of existing testing procedures and problems of interoperability in early TTCN-3 products. Testing and development environments typical for electronic devices manufacturing are outlined and it is shown where in the process future benefits through further formalisation of test definition and implementations may be found.

The 5G-Crosshaul Packet Forwarding Element pipeline: Measurements and analysis

This paper is focused on the 5G-Crosshaul Packet Forwarding Element (XPFE), which is the packet forwarding element of the 5G-Crosshaul network architecture. The XPFE integrates multiple technologies which allow to transport traffic from multiple tenants and of different nature over the same infrastructure. Hence, the paper is focused on the performance of this essential element of our network, providing some end-to-end delay measurements and analyzing the behavior of this delay. Likewise, we have fitted the appropriate probability distribution for these measurements, which allows us to infer some confidence intervals for the prediction of the maximum number of hops supported by delay-sensitive fronthaul traffic before being processed in a 5G-Crosshaul Processing Unit.
