This Annex describes a set of collaboration scenarios and deployment options of the 5G Media Streaming architecture. The intention is to illustate different deployment options.
Note that the scenarios focus on the ownership of the functions. Scalability realizations such as a CDN are not illustrated. As result of the scalability considerations, the M4d-serving 5GMSd AS and/or M5d-serving 5GMSd AF may:
Consist of multiple (physical) servers, which may be addressed using a single FQDN. A load balancer forwards client requests to one of these servers. Forwarding may be via HTTP redirects or transparent towards the client.
Consist of multiple (physical) servers, where different servers, or different groups of servers, may be addressed with different FQDNs. The client may be made aware of this via the manifest (i.e. listing multiple base URLs).
Be addressed with a single FQDN. For example, the MNO AS is mostly transparent and acts as a proxy/cache.
