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 System Architecture Deliverable contains information of how the software System is designed and constructed. It explains how the code is structured using objects, models and services and the core technology used. The document content contains illustrations, diagrams and narrative text. • Infrastructure Specifications. The Infrastructure Specifications Deliverable contains information regarding the physical or virtual server hardware environment and includes basic server specification information like the operating System version. • Analysis and Design Summary. The analysis and design summary Deliverable must contain the following information: o Description of issue or enhancement; o Summary of analysis conducted to determine the root cause of the bug and proposed changes to software code or configuration; o If a bug, description of the steps to reproduce the issue; and o Recommended changes to be made to software code, architecture, configuration.
Software Architecture. This must be prepared and submitted according to the standards defined in the Construction and Implementation Deliverables section.

Software Architecture. The Provider’s responsibilities include the following:
Software Architecture. All DSP software conforms to the VP Open software architecture. All DSP modules work on 64 sample blocks of data (8 ms). in each 8 ms interval, the DSP performs the following functions:
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.
