An FPGA based cut-through switch optimized for one-step PTP and real-time Ethernet

Abstract: This paper presents an FPGA based Ethernet cut-through switch that is optimized for one-step PTP clock synchronization and fast forwarding of real-time Ethernet frames. Whereas a standard switch ASIC provides sophisticated mechanisms for switching of non-real-time frames, an attached FPGA implements cut-through switching of real-time frames and synchronization events. Moreover, timestamping of synchronization events, one-step bridge delay compensation, peer-delay responses for power profile and a servo clock are implemented in hardware. The results show that even a low-cost Xilinx Spartan 6 FPGA comprising 47,000 Look-up tables can fulfill the requirements for switching 6 Ethernet ports at 100 Mbps. The combination of cut-through forwarding and transparent one-step clock synchronization yields to bridge delays less than 3 microseconds for both real-time Ethernet data and synchronization events. Therefore, the presented switch can be flexibly integrated into time-synchronized real-time networks in order to provide improved switching functions.

Slicing the V-Model -- Reduced Effort, Higher Flexibility

Abstract: Companies requiring a formal software process model tend to choose the V-model. Having its advantages in a strong focus on verification and validation, the main drawbacks of the V-model are the need to create a large amount of documentation, to keep this documentation continuously updated and to manage trace ability of requirements implementation and testing. As it is based on the waterfall process model the timing behavior of the V-model is considered to be stiff. Additional complexity arises whenever teams work together in globally distributed environments. All these aspects reduce the software productivity of the teams when using the V-model. It is known that agile processes solve some of the mentioned problems. However, agile processes are not always accepted in formal environments, e.g., if certification bodies need to approve safety critical developments. This article proposes a new approach, called "sliced V-model", where documents are split into work items and these work items are linked between the documents, forming small and independent "V" shapes. Working with such so-called "V" slices downsizes the efforts for keeping documents updated, simplifies the management of trace ability and increases flexibility. Since the sliced V-model requires the utilization of a web-based repository, it is easy to apply in globally distributed teams. An example of successful implementation in a globally operating industry company is shown.
