  1. 5G + Cloudification = Slicing Luis M. Contreras Telefónica GCTIO – Transport Technology and Planning INSERT TYPE OF SECURITY USE NECOS Industrial Workshop, Campinas (Brazil) 18.10.2019
  2. 2 • The driver: 5G • The enabler: Cloudification • The product: Slicing Agenda INSERT TYPE OF SECURITY USE
  4. 4 5G implications Requirements • 10x bandwidth per connection • Low-ms latency • Five 9’s reliability • 100% coverage • >10x connections • 50Mbps per connection everywhere • 1000x bandwidth/area • 10 year battery life • Reduction in TCO Applications • Enhanced Mobile BB • Connected vehicles • AR/VR • S-UHD/3D Video • Haptics/Sensing • Massive IoT • Remote machine control • Mission critical services • Fixed-wireless access • … Customer segments • Consumer • Auto industry • Health • Industry 4.0 • Agriculture • Smart City/Public sector • Smart building • Utilities • Education • Transport • … MNO biz model • B2C • B2B • B2B2C
  5. 5 5G Ready Transport Network 5GTransportNetwork  Upgrade of nodes’ capacity in the Telefónica IP FUSION architecture, with higher bit rate interfaces, mainly at NNI  Generalized upgrade of capacity also at UNI (10G/25G for Access, 50G/100G for Aggregation) leveraging on spread computing capabilities to offload the backbone  New bands for µW/mmW microwave backhaul  Upgrade of HW platforms of the nodes, in order to support new data plane technologies  eCPRI support for VRAN Evolutionary path foreseen for generalized deployments in Telefónica networks in three waves • Wider deployment of RAN functional splits • Densification in the access, increasing the number of connected sites • Virtualization of 5G core, creating diverse service anchors • Control plane and user plane separation DU Deterministic network Performance optimized network DRAN CPRI eCPRI Edge Compute Core Data Center vCU Disaggregation (Open Networking) Virtualized Flatter & high capacity network LTE 5G Content/Services Virtualized Content/Services Logical layout Increase of existing 4G capacity eMBB 5G services uRLLC 5G services 2020-2021 2021-2022 2022-2023 iFUSION (Control Plane Architecture): standards-based SDN interfaces enforcing Traffic Engineering
  6. 6 5G Ready Transport network: technology Data Plane Control Plane 5GTransportNetwork • Need for traffic differentiation in order to segregate traffics from different services and tenants • Reduction of latency (uRLLC) • Delivery of high BW (eMBB): Higher speeds (25/50/100) towards network access • Dual core E-band HW for 20 Gbps over a single link in short term (W & D-bands for +30Gbps capacity in short-distance, p-t-p LOS • Flexible and fast reconfiguration of transport network leveraging on source routing supported by control plane elements (e.g., PCE) • Unified orchestration including different network domains and virtualization infra (UNICA) • Slicing as form of logical separation of services supported on top of the same infrastructure • Programmability through standard data models HW SW DetNet introducing determinism in the service delivery TSN enabling frame preemption and rich queue management Flexible Ethernet allowing rapid cross connection at MAC level Source routing protocols for flexible traffic steering 25/50/100 Gb Bi-Di for saving fibers Telemetry enabling intelligent diagnosis and proactive control and management Traffic engineering to manage service constraints Slicing incorporating mechanisms for soft or hard slicing Synch including frequency and phase reqs of 5G Standard data models to enable programmability • Extended fiber connectivity to the sites complemented by +Gbps capacity wireless transport (MW, mmW (E & D bands)) • New data planes for guaranteeing deterministic delay and protocols enabling flexible anchoring, supporting hard and soft slicing • Stringent synchronization requirements • Increased maturity of whiteboxes for commoditizing site connectivity Alternative Topologies and new technologies are needed for 5G Synchronization • Mandatory Frequency & Phase Synchronization for LTE-A and 5G. • More stringent requirements for synchronization (+/- 500ns PDV or less). • Distributed Grand Master Clocks at HL4-level with Partial On-path support, ePTRC and SyncE to improve holdover in case of GNSS signal loss. Full On-path support mandatory for future sync distributions. Technology Radar
