The key component is this federated multi-access edge platform. The platform sits between applications and underlying heterogeneous edge infrastructure and also abstracts the multi-access interface and exposes application developer friendly APIs. This blueprint leverages upstream project KubeEdge as baseline platform – this includes the enhanced federation function (Karmada).
Telco/GSMA side complexities (5GC/NEF etc.) need to be thought through and designed appropriately in order to realize extremely low latencies (10 ms) requirements desired by typical MEC use cases. For the multi access, we may initially use a simulated mobile access environment to mimic a real time device access protocol conditions as part of the initial release/s.
Key Enabling Architectural Components
Federation Scheduler (Included in Release-5)
As a “Global Scheduler”, responsible for application QoS oriented global scheduling in accordance to the placement policies. Essentially, it refers to a decision-making capability that can decide how workloads should be spread across different clusters similar to how a human operator would. It maintains the resource utilization information for all the MEC edge cloud sites. Cloud federation functionality in our blueprint is enabled using open source Karmada project. The following is an architecture diagram for Karmada.
