Evolving the network for 5G

Jeff Schmidt of Telstra presented on evolving networks for 5G. Currently, networks have physical nodes with manual configuration and provisioning that limits ability to prioritize different traffic types. The presentation discussed using network slicing to create logical partitions of network resources dedicated to different services like mobile broadband, IoT, and mission critical applications. This would allow isolating resources, selective feature enablement, and dedicated resources to guarantee service level agreements. Key points included using network slicing concepts from 4G in 5G core networks, challenges around orchestration, addressing, scaling, latency and throughput requirements.

Definition - A set of network functions and corresponding resources necessary to provide the required telecommunication services and network capabilities Aim - Optimising network implementation to meet different requirements Types – Retail Mobile Broadband service, Customer VPN, Mission critical, IOT, etc Benefits : 1. Manage risk – isolate resources 2. Selective enablement of features 3. Geographic footprint ie latency 4. Dedicated resources as SLA guarantee Network Slicing

- 15. Data Centre architectures are extending into access networks with NFV Orchestration Network slices to support different traffic types ie IOT vs Video will allow simplified configurations per PGW, for example, but many more PGWs will be required - complexity Network slices will logically separate some network services but not all so integration to shared services will be required - addressing Infrastructure addressing – orchestration, scale and network slicing Scaling network services - load balancing ? Tighter latency requirements Core network throughput – cost Network management – visibility Service chaining Challenges
