Network Slicing Landscape: A holistic architectural approach, orchestration and management with applicability in mobile and fixed networks

June 29, 2018 – Morning


  • Alex Galis, Professor UCL, UK
  • Kiran Makhijani, Future Networks, Huawei Technologies, USA

Tutorial description

This half-day tutorial will present the concepts, design and technologies enabling Network Slicing (NS). NS is both an old and new idea. While its scope and definition continue to evolve, there is reasonable level common understanding of the key central role it will play in future network and service delivery scenarios.

The significant value of network slicing architecture will be seen in terms of dynamic and non-disruptive control, operation and scaling of services in a network slice by the tenant of the slice.

In order to achieve this, a fundamental change in how we administer networks is required in terms of abstraction, separation and mapping of forwarding, control and management aspects of a service. There exists a possibility of applying already mature methodologies such as SDN, NFV, service chains, network virtualization, etc. The challenge lies enabling an operator to flexibly use such tools in a light-weight manner with in a viable architectural framework. The three other major challenges are: a) applying least-effort and minimal provisioning through auto-orchestration of such slices, b) applying new or existing traffic and service engineering techniques to provide dynamic resource assurances for the services, and c) simplified framework for enablement of network slice as a service.

The first part presents the main slicing concepts and their history, key slicing characteristics and usage scenarios, Standard Organization activities in network slicing (ITU-T, IETF, ETSI, other SDOs), Slice Life Cycle Management, Management & Orchestration frameworks, Research & Development projects on Slicing. This part will conclude with identifying research and development challenges in Network Slicing.

The second part presents an industry’s perspective on an overall architecture of network slicing and corresponding operations to demonstrate how an end-to-end slice couple be deployed and managed. It shows many existing standard techniques can be used to simplify network slice workflows. Use case will be thoroughly analyzed. This part will wrap up with a report on progress and approach currently used for standardization of requirements of network slices.

Advanced Topics in Architectural and Robust Operational Research for Virtual Networks

June 29, 2018 – Morning


  • Kohei Shiomoto, Professor  Tokyo City University, Japan
  • Dimitri Papadimitrio, Senior Researcher at Nokia Bell Labs

Tutorial description

This tutorial presents recent advances in architecture and robust operation of virtual networks. Network virtualization provides the ability to i) concurrently use physical network resources and functions for multiple instances of (virtual) networks while providing isolation so that there is no interference which may affect network performance, ii) aggregate/combine multiple such resources to obtain increased capabilities, and iii) operate heterogeneous network resources and elements as abstract resources, in which a given virtual resource need not directly correspond to its component resources. It aims at bringing benefits such as innovation/deployment of new business roles and players as well as efficient network resource utilization. These benefits are brought by re-architecting network systems to dis-aggregate vertically integrated systems into components. However, despite prominent research and development efforts over last decade, network virtualization still requires addressing several architectural challenges. For instance, the architecture of network virtualization needs to address the dis-aggregation of network systems into components. The conventional mechanism-driven management, that implies the complete understanding of the behavior of each component of the system, should be abandoned and instead rely on data-driven management by applying machine learning techniques. There are also many active research topics on-going in the area of re-architecting middlebox, high-performance NFV platform, and state management in NFV. We will overview recent research in those areas.

The design of reliable virtual networks as well as their operation and management require to account for the probabilistic variability affecting, e.g., customer demands or the physical resources availability, e.g., due various failures. Uncertainty has become the central notion to capture for the optimal solving of various design, dimensioning/provisioning, location, allocation, scheduling and routing decision problems (as well as their combinations) for virtual networks. For instance, the operational model used for the joint server/cache placement, their dimensioning/sizing and demands assignment in virtual content distribution networks leads to strongly interrelated content placement and demand assignment decisions. Hence, preserving the continuity of service delivery while ensuring efficient resource management, requires capturing demand uncertainty as part of the operational model. Optimization under uncertainty has been approached by mathematical programming paradigms that differ mainly in the definition, representation and handling of uncertainty, i.e., by known probability distributions (stochastic optimization) or uncertainty sets (robust optimization). For this purpose, the second part of this tutorial covers in detail the applicability of robust optimization to virtual networks.

A Language and Framework for Prototyping and Experimenting with Edge-Oriented IoT

June 29, 2018 – Afternoon


  • Muthucumaru Maheswaran, Associate Professor, McGill University, Canada

Tutorial description

To obtain the most benefit out of edge computing, we need to rethink how applications are developed, deployed, and orchestrated on to the cloud, edge, and IoT resource stack. This tutorial will have three parts. First part will examine the important issues introduced by edge computing for programming IoT applications. The IoT applications primarily want to use edge computing for low-latency resource accesses. Other benefits they seek from edge computing include context-sensitive processing (including machine learning at the edge) and reduced network loading. We will examine IoT with and without mobility (e.g., vehicular IoT). Also, in this part, we introduce many edge programming patterns that could be used in existing and future application scenarios. The second part will discuss a programming language expressly designed for programming the cloud, edge and IoT resource stack. We will introduce the language (JAMScript) in depth and illustrate how it supports edge processing. In particular, its support for handling high-speed data processing at the edge, adaptive placement of functions at the edge or cloud, and failover from edge to edge or edge to cloud will be examined. The language itself is a fusion of C and JavaScript with additional constructs to support remote procedure calls and coordinating the data placements. The third part of the tutorial will show example application designs and their implementations using JAMScript. These example applications will be deployed on a Docker container-based emulator and very large cloud, edge, and IoT configurations will be run. A hands-on exercise on JAMScript will be provided for the tutorial participants that will show how JAMScript and the emulator could be used for developing interesting large-scale edge applications.
