Futurecom 2019 - NECOS

  1. 1. Fábio Luciano Verdi UFSCar http://www.h2020-necos.eu/ Cloud Network Slicing: Challenges and Lessons learned from the NECOS Project
  2. 2. Agenda ● Introduction to cloud network slice ● Use cases ● The NECOS project ○ What is NECOS ○ Challenges and lessons learned
  3. 3. The journey
  4. 4. What is a cloud network slice? … 5G PPP Architecture Working Group View on 5G Architecture (Version 2.0) From network slicing to cloud network slicing
  5. 5. What is a cloud network slice? ● ● ● ● ●
  6. 6. Use cases ● Mission-critical Ultra low latency communication ● Massive-connectivity machine communication (e.g. Smart metering, Smart grid and sensor networks) ● Extreme QoS ● Independent QoS isolation design ● Independent operations and management ● Independent autonomic management functionality ● Independent cost and/or energy optimization ● Independent multi-topology routing ● Sharing Infrastructure: Enablers for sharing infrastructure safely and efficiently (Multi-tenant)
  7. 7. Roles ● Infrastructure Owner owns the physical infrastructure (network/cloud/datacentre) and leases them to operators. It becomes an infrastructure slice provider (ISP) if it leases the infrastructure in network slicing fashion. ● Infrastructure Slice Provider – An ISP, typically a telecommunication service provider, is the owner or tenant of the infrastructures from which network slices can be created. ● Infrastructure Slice Tenant – An infrastructure slice tenant (IST) is the user of specific network/cloud/datacentre slice, in which customized services are hosted. Infrastructure slice tenants can make requests for the creation of new infrastructure slice through a service model.
  8. 8. Types of slices and control responsibilities
  9. 9. Challenges ● Slice Life Cycle Management: ○ creation and connection of physical and virtual resources (computing, networking and storage); ○ activation / deactivation, protection, elasticity, extensibility, safety, and sizing of the slicing model per network and per network cloud for slices in access, core and transport networks; ○ different technological solutions / VIMs: Openstack, Kubernets, etc. ● E2E multi-domain Orchestration ○ autonomic control of slice life cycle management, including concatenation of slices in each segment of the infrastructure (in data, control, and management planes); ○ autonomic coordination and triggering of slice elasticity and placement; ● Network Slices with guaranteed QoS / KPIs characteristics - Precision Network Services
