Panel 5

Maturing E2E network and cloud slicing: Where are the frontiers?


This panel discusses the key challenges for efficient deploying network softwarization and e2e network & cloud slicing technologies toward coming 5G launch in 2020 and beyond. The panel invites distinguished experts on deeply programmable networking, wireless and mobile network softwarization, and open software platform suites for Access, Radio Access, Core, Edge Networks & Clouds. After communicating advances in state-of-the-art technology and standardization activities, the panel interactively would examine a set of thought-provoking questions with the participants.

Network slicing (NS) is an approach of flexible isolation and allocation of network resources and network functions for a network instance, providing a high level of customization and quality service guarantee. NS transforms the networking perspective by abstracting, isolating, orchestrating, softwarizing, and separating logical network components from the underlying physical network supporting the introduction of new network architectures and new approaches to service delivery and provider-tenant business models.

In general, a particular network slice consists of a union of subsets of (connectivity, storage, computing) resources & (Virtual) Network Functions & Service functions Functions [RFC7665] at the data & control & management planes at a given time that are managed together to provide a logical networking infrastructure in support of a variety of services.

Network slicing enables at a given time the dynamic creation of multiple, parallel sub-networks of different features by flexible isolation of allocated to a slice network resources and network functions and providing high levels of customization and quality guarantees. Network operators can use NS to enable different services to receive different treatment and to allow the allocation and release of network resources according to the context and contention policy of the operators. Such an approach using NS would allow a significant reduction of the operations expenditures.

The panel would like to discuss not only research and development aspects but also the perspectives of standardization, stakeholder eco-systems and benefits, social acceptance, and application/service viewpoints in order to attract the attention from the conference participants.
