O-RAN Slicing Architecture and Use Cases
Arda Akman, Juniper Networks

Description

Network slicing is considered to be a key pillar of 5G, enabling the creation and management of customized networks to meet the specific service requirements demanded by different applications, services and business verticals. Introduction of such an architecture to meet the vastly varying service demands requires the 5G mobile networks to support very high data rates, service availabilities and very low latencies, and other requirements which are expressed through Service Level Agreements (SLAs) between the mobile operators and the business customers. As network slicing is an end-to-end feature, including the core network domain, transport network domain and the radio access network (RAN) domain, these service level requirements needs to be met for the collection of these domains, and especially in the RAN given the service variability of RAN by its nature. For this purpose, detection of RAN slice SLA violations and assurance of RAN slice SLAs is a key challenge to be resolved which is where O-RAN’s open interfaces combined with AI/ML based innovative architecture enables such challenging RAN slice SLA assurance solutions to be implemented.

FlexNGIA – The New Frontiers for Future Tactile Internet
Mohamed Faten Zhani, ETS, Montreal, Canada

Description

From virtual reality and teleportation, to telepresence, augmented reality, holograms, and remotely‑controlled robotics, these future network applications promise an unprecedented development for society, economics and culture. Unfortunately, today’s Internet falls short when it comes to providing the stringent performance requirements imposed by such applications. This is due to several fundamental limitations in the design of the current network architecture and communication protocols. As a result, there is a pressing need to rethink the network architecture and protocols, and efficiently harness recent technologies in terms control and data plane, in-network computing, cloud computing, virtualization and softwarization to devise the next-generation tactile Internet. In this talk, we start by analyzing the characteristics and requirements of future networking applications and highlight today’s Internet limitations. We then draw a rough sketch of FlexNGIA (www.FlexNGIA.net), a Flexible Next-Generation Internet Architecture that leverages in-network computing, network softwarization and virtualization to satisfy the requirements of future Internet applications and services. We also discuss through some use-cases how FlexNGIA could ensure the service level guarantees required by some of the future network applications.

Description

The current convergence trend between computing and networking eco-systems puts software into an unprecedented and dominant role in operational communication environments. Computing, storage and connectivity services along with application instances are foreseen to be dynamically deployed in the form of slices of virtualized assets within a so-called Software-Defined Infrastructure (SDI) leveraging general-purpose processing and communication hardware, altogether being flexible managed and made available under “As-a-Service” paradigms in the spirit of Cloud Computing. This concept is summarized in the idea of Slicing, which has become a central piece in the evolution of telecom networks, as we witnessed in the past three editions of S4SI and other scientific and industrial venues.
