MEF digital service architecture and LSO are combined and extended to demonstrate the enterprise-dedicated network slice service over private 5G, metro, and core transport to edge/cloud infrastructure. Extreme services, such as low latency real-time video analysis, jitter-less robotic communication, ultra-capacity storage data transfer, and xHaul transport are enabled over the end-to-end slices with LSO orchestration across multi-layer underlay slices and 5GC slices.
To illustrate this AI/ML-based use case, MEF 3.0 PoC (138) is implementing what we term ‘extreme slicing’ over 5G to a MEC, to support both facial recognition and fish recognition along the coastline in Okinawa, Japan, protecting these scarce marine resources.
5G/private 5G is accelerating automation and digital transformation in various industries. For such cases, E2E dedicated network service over 5G is necessary for enterprise customers to enable future extreme services. This PoC demonstrates E2E dedicated slice instantiation between 5G and transport SPs, and also how it helps enterprise customers’ business in terms of service order and management.
Current network slice standardization works specializing in transport, RAN, and CN vary in architecture and service model/APIs, creating isolated islands of standard and increased operating costs, while limiting the interoperability between RAN/CN and transport networks. Service providers should accelerate the work of potential E2E network slices as an underlay service for private 5G and increase adoption, speed-up revenue realization and improve customer experience.
An increasing number of public and enterprise 5G customers and service providers will be seeking standards that enable them to order or provision and manage end-to-end private 5G connectivity to MEC and Cloud, through network service, for easier inter-SP interconnection and orchestration.
Standardized service models for E2E dedicated network service, including multi-layer underlay slices, as well as interconnection and performance implementation agreements, in addition to standards governing interoperability between metro and core transport slices, and container-based 5GC slices are required.
The lack of an organizing feature for E2E slice interconnection, control, and management causes individual provisioning and monitoring of service providers, leading to frequent, complex inter-operator operational procedures, especially for SLS monitoring.
