Communications pilot
The communications pilot aims to elaborate on the usability of 5GTANGO platform to provide a complete video conference service which handles real-time traffic using the 5GTANGO platform. Currently, the pilot focuses on the development of components that use the 5GTANGO platform for these four use cases:
- Best-effort video-conference services
- Premium video-conference services (Gold and Silver QoS)
- Edge video-conference services
- Video-conference scaling out/in services

Use cases description
Best-effort video-conference services
This use case considers a network service which provides real-time communication capabilities to enable functionalities like video-conference, IM and other real-time collaboration tools. The service is deployed in the core of the operational infrastructure.
Premium video-conference services (Gold and Silver QoS)
Video-conference service is sensitive to some of the QoS measures, such as bandwidth, packet loss or RTT. In this, we might consider offering two kind of services: one for premium users (Gold) with high QoS requirements and another one for free users (Silver) with lower QoS requirements.
Edge video-conference services
In this use case, we consider the improvement of the service through taking into account the delay-sensitive VNF, such as the VNF-MS.
Video-conference scaling out/in services
The last use case, considers the need to increment the number of instances of some of the VNF.
Network Service Components
The network service is composed by 5 VNF which are:
- VNF-RP: Reverse Proxy exposing the service and performing the load balance.
- VNF-WAC: Server managing the WebRTC communication.
- VNF-BS: Backend services needed by the system.
- VNF-DS: Dispatcher.
- VNF-MS: Media server.
Test components
The following scripts are used to generate probes able to test the services. More information about them can be found in the wiki page of the project.
- users.py: Python script used to generate or remove users through the service REST API.
- check-registered-users.py: Python script used to retrieve the number of registered users in the service.
