Information

• Traffic Routing:

◦ Through appropriate Filtering rules, traffic is routed to an edge network (e.g. LADN)

◦ Through appropriate DNS resolution, an Application Server is selected in the LADN

◦ If no AS instance is running, AF together with Orchestrator launch a new instance of the AS

• Slice Configuration:

◦ AS criteria and requirements

◦ DNS resolution rules

◦ AF configuration to manage AS

Network-Based Media Processing (NBMP)

• MPEG is defining a Media Processing layer ◦ Cloud Platform-agnostic

◦ Can run on top of 5G Core and other cloud services

• Interfaces for Control Plane◦ Workflow description and control

◦ Load customized media processing

◦ Configure discovery and placement of media processing

◦ Build media processing pipeline from existing and custom processing entities

• Interfaces for User Plane• Formats for media and metadata
