● Hyper Scalable & Distributed Core

○ Edge ready

○ Provides local break out for user traffic

○ Headless run-time

● “All access” Convergence

○ LTE, Wi-Fi, P-LTE, 5G

○ Vendor / Transport Agnostic

● Highly Available

● Micro-services, CUPS, Containerized

● Northbound REST APIs for configuration,

visualization, policy & subscriber mgmt, &

lifecycle management

● MNO Core Integration*5G is under development

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

MNO Existing Core Network Functions

NMSConfig 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

Runtime Abstraction
