Design and Programming. The first entry point for experimenters to access the resources offered by SoftFIRE is the SoftFIRE portal. This portal aggregates information and services useful and needed by the experimenters. A set of tutorials provides knowledge needed on how to book and use resources. As written above, the methods provided by the testbed to allocate and provision services are aggregated within the SFA interface. SFA uses XML RSpecs to describe either requests, manifests or advertisement of resources. The portal offers example RSpecs to provision e.g. an Open5GCore instance. If the user wants to add own implementations of Virtual Network Functions the portal offers suitable interfaces and tutorials on how to create and build the needed service descriptors and packages. Finally, experimenters can download X509 certificates in order to authenticate against the testbed. Preparation phase • In any case, upload the image to the SoftFIRE software portal • Upload package to FIT/OB through SoftFIRE software portal As described in the D2.1, the SoftFIRE Software Portal (SSP) is in charge of dealing with the images and the VNF packages. The Experimenter will interface with the SSP in order to upload the already prepared images and VNF packages. Hence in a second moment, these VNFs will be available to be deployed into the federated testbed. An image has to contain the VNF required software, even precompiled, in order to allow the VNF to be instantiated in a short timeframe and without any dependencies besides the other deployed VNFs. The name or id of the uploaded image has to be then specified into the VNF package. The SSP is in charge of deploying the package directly to the NFVO. The correct uploaded images have to be specified thus the VNF that will be available afterwards will point to that image containing the correct software.
