Software Architecture Clause Examples
The Software Architecture clause defines the overall structure, design principles, and key components of the software system to be developed or delivered under the agreement. It typically outlines the main modules, their interactions, and the technologies or frameworks to be used, ensuring that both parties have a shared understanding of the system's technical foundation. By establishing these architectural guidelines, the clause helps prevent misunderstandings, aligns expectations, and provides a reference point for evaluating the system's design and future modifications.

Software Architecture. Following the comments from the first year technical review, this appendix has been added to describe the software modules that will be developed in the prototype of the COSIGN control layer. The objective is to highlight the components that will be implemented in the OpenDaylight framework as new OpenDaylight plugins developed from scratch or as extended versions of already existing OpenDaylight plugins. In this latest case, this section will provide details about the modifications and enhancements that will be needed to meet COSIGN requirements. Moreover, some components related to the composition and delivery of virtual optical slices will be implemented as OpenVirteX plugins and will require the extension of the OpenVirteX platform in support of optical resources, as documented in the next tables. The outcomes documented in this section are the result of the software design activities carried out in T3.1, T3.2 and T3.3 from M13 to M15. These activities have taken as input the functional architecture documented in the previous sections of this document and, for each functional component defined in Section 4.1, have defined a set of software modules which will implement the associated control plane functions (functions derived from the requirements, as detailed in Table 2). The list of the resulting software modules is summarized in Table 5, which also specifies the prototype release(s) where each module will be included (i.e., preliminary release in D3.3 “SDN controller for DC optical network virtualization and provisioning software prototypes: Preliminary release” at M24 and/or final release in D3.4 “SDN controller for DC optical network virtualization and provisioning software prototypes: Final release” at M30). The following tables describe in details each software module, defining the software architecture which marks the milestone MS14 (Intra-DC control plane high-level architecture), planned at M15.

Software Architecture. The purpose of this Section is to describe how the proposed modules are integrated into one system, focusing on three separate aspects: ● Communication between the modules ● Coordination between the modules ● Deployment of software components to a shared compute platform In doing so, the section will discuss the difficulties encountered during the deployment of different modules and the adopted solutions.

Software Architecture. The content delivery software consists of following main components: FIBRE control framework to provide the slice of OpenFlow enabled devices (packet, optical), media server and virtual machines to host software’s. Media Solution: FOGO 4k Player and Streamer. The FOGO is a proprietary solution and will be available till the end of the FIBRE project. POX controller: this is the SDN controller which runs on top of the experimenter slice. It utilizes the OF Interface to control the slice resources. The controller application is hosted over python DJANGO framework. The DJANGO framework consists of application called POX_CW which houses the content delivery software and interfaces. The main modules of the controller are as follows.

Software Architecture. The software consists of a number of threads which are running on the 2 processors, each managing processes with a number of specific performance requirements. Not all the software threads have been implemented inside this project. On the LINK processor [2 in figure 12] a scheduler is managing the processor item allocation and the priorities of each of these processes. This scheduler is interfacing to a K-API [Kernel API]. On the APP processor [1 in figure 12] an OS will be implemented. This OS remains to be selected. An appropriate wireless sensor operating system. Operating system alternatives are RIOT, Contiki, TinyOS, Linux… The RIOT operating system is a promising recent open source European initiative focused on embedded nodes networks that requires low power and computational resources. Short description of the software components: at networking layer: BTLE Link layer interfacing to an HCI –API. HCI is also accessible as HCI commands on the SPI interface. The BTLE link layer is Bluetooth specification V4.0, V4.1 and V4.2 compliant. 802.15.4 MAC layer interfacing to a proprietary 802.15.4-API. Also accessible on the platform SPI interface. The MAC layer is compliant with the 802.15.4 standard. The ZIGBEE and BTLE thread are based on external solutions. SPI external interface. SPI-based debugger that can survive the deep sleep mode. Problem with JTAG debugger is that they require the JTAG interface to be powered in order to be able to run the debugger. This is an issue in this device, as the goal is to put the device in a sleep state most of the time where the JTAG is not powered. The issue can be resolved by doing a SPI debugger. Application layer on the application processor. Communicates with the LINK processor over a COMs API. Following table summarizes the software memory [program and data] sizes.
