prepares the content for the Teleport and can receive feedback data from the SATCOM Return Link (RL). n SF3 – SATCOM: connects the Cloud Uplink Preparation with the Micro- Edge Devices via an Uplink location, satellite network and antenna.
n SF5 – Service Provisioning: manages the ecosystem and
exchanges control and performance data.
n SF4 – Micro-Edge Device: provides edge functionality and connects to the
satellite link, such as Digital Video Broadcasting – Second Generation Satellite Extensions (DVB-S2X) and Fixed-Interactive Multimedia Services (FSIM).
by the reference satellite(s). It also can perform content manipulation services to support distributed 5G-EMERGE Micro-Edge device terminals. Together with the Uplink Edge, this is part of the 5G-EMERGE Cloud Uplink, which communicates with the 5G-EMERGE Cloud Service Management layer to receive data about popularity of content and coordinated tasks with the Micro- Edge devices. 4. Multicast Server: This server will prepare the content for satellite distribution. 5. RF Uplink: It sends the multicast IP stream in a modulated carrier to the satellite. At the same location, data from the RL can be received and demodulated. Existing physical layer protocols shall be used over the
In turn, each SF consists of several actors/components, which are briefly described below: 1. Content Provider: Online delivery starts at the Content Provider (CP) that publishes content via an Origin server. 2. 2CDN Origin: The Content Delivery Network (CDN) provider picks up the content from the CP Origin. 3. Uplink Edge: This is a 5G-EMERGE- specific server that is envisaged to run on a cloud stack in a well- connected Gateway and that manages both the reception from the CDP Origin and the transmission of selected content towards a Teleporter. This Edge server’s main function is to cache content that is popular in the region covered
6. Satellite: It broadcasts the signal over a region and provides the RL.
7. Antenna: It is the first part of the 5G-EMERGE far edge terminal, which will be optimised for different use-cases including fixed and moving reception. 8. Edge terminal on the 5G-EMERGE far edge: It comprises the satellite or 5G networking layer performing the local breakout of user plane traffic towards the virtualised stack that runs the applications and integrates with the northbound Uplink Edge and the Service Provisioning layer.
