Magma Roadmap Principles

1. Build what is needed

Deployment and use-case focused with input from our partners and the Magma ecosystem

2. Rapid iteration

Flexible roadmap, quarterly releases following DevOps principles

3. Software delivery

Hitless upgrades, lightweight delivery (containers), independent upgrade paths for Orchestrator and Access Gateway

Conﬁg vs. Runtime Abstractions

Orchestrator

HSS Gx, Gy S6a OCS PCRF Gx Gy S6a DRA Federation Gateway

MNO Existing Core Network Functions

NMS

Config Abstraction

● Logically centralized orchestrator

● Day-0, Day-1 configs managed through APIs or through delegation to MNO legacy core via FEG ● Authoritative durable configuration state for the

entire system

● Big graph representation at Orc8r (Entities and Edges)

AGW

● State generated in the network due to the operation of the network

○ Session state, UE state (registered/unregistered, connected/idle), data-path state, metrics, etc.

● Function of config state and authoritatively owned by the network

● Transient in nature
