The gateway provisioning logic contains the directives to internally provision the gateway, e.g., to install and configure device services, cloud communication libraries and data and control points.
We have shown how SDG-Pro provides API encapsulation of the most important aspects related to gateway provisioning and governance.
The most important thing to notice here is that SDG-Pro provides software-defined gateway specific provisioning APIs.
This section describes the main functional blocks inside the gateway for the provisioning of E2E QoS guarantees over a DVB-S2 satellite system.
In this example, we show how to provision a gateway with Sedona runtime.
The new gateway would bypass this provision. .
Second, developers use the software-defined gateways to programmatically provision and deploy required application services, but also to configure an execution environment for such services.
In our conceptual design of software-defined IoT cloud systems, such gateways abstract resource provisioning and governance through well-defined APIs and they can be composed at different levels, creating virtual runtime topologies for IoT cloud applications.
In order to provision a software-defined gateway, initially the developers need to specify the software defined gateway prototypes.
Currently, our framework supports software-defined gateways based on kernel supported virtualization, but virtualization choices do not pose any limitations, because, by utilizing the well-defined API, our gateway prototypes can be dynamically configured, provisioned, interconnected, deployed, and controlled.
Provisioning a software-defined gateway includes configuring, deploying and installing different artifacts such as device services, libraries (e.g., cloud communication protocols) and other binaries atop the newly created gateway instance.
