18 Network Slicing
Three Alternative Network Scenarios Modeled 1. One big network 2. Separate networks 3. Network slicing This study was restricted to evaluating the impacts of network slicing in the core network only. 19
Benefits of Network Slicing
Overall Economic Impact of Network Slicing Network slicing enables: New revenue generation Lower opex Greater capex efficiency Result: Significantly increased economic benefit through new service launches.
Transport Network Slicing System View MFH1 Slice MFH2 Slice MFH3 Slice MBH Slice EBH Slice MEF Ethernet Service based on EVCs Ethernet Service Slice is a group of Ethernet Services (EVC) A new Group of Ethernet Service is now introduced
Transport Network Slicing Representation Slice Representation Examples - A Group of EVCs Slice EVC 1 EVC 2 EVC 3 EVC 4 Single S-Tag = EVC, Enhanced MEF tools (e.g., Trunk/OVC+, Envelope+) to represent Slice ID Single S-Tag Higher order bits=slice ID, Lower order bits=evc Double S-Tag Inner Tag=EVC, Outer Tag=Slice ID PBB S-Tag=EVC, B-Tag+I-Tag=Slice ID MPLS S-Tag=EVC, MPLS Label=Slice ID 23
3GPP Network Slicing E2E Service View 5G America White Paper Network Slicing for 5G Network & Services Fronthaul is inside the RAN Slice between RRH and BBU or between RRH & DU and DU and CU(BBU) Backhaul is between RAN and Mobile Core Network or between RAN and Wireline Network for Wireline Services RRH DU CU There is an East-West association between RAN, Core, and Transport 24

3 MEF Services over 5G
MEF Services Over 5G Why? More and more traffic is now terminated on mobile devices Customers would like the same SLA at the office, home, or traveling Fiber availability is limited Copper plants are old and deteriorating Optimized for low bandwidth T1/E1 replacement Low CAPEX (FedEx vs. Technician) 31
Advantages of MEF Services Over 5G SERVICE ON DEMAND (TIME TO DELIVER = REVENUE) FAST ACTIVATION OUT-OF-BAND MANAGEMENT FOR SDN NETWORKS SUPPORTING IOT USE CASE 32
MEF Services Over 5G MEF services Carrier Ethernet IP Network slicing allows customer separation for EVC end-to-end 5G adds native support for IP or Ethernet frames/service at the UE Service Provider End-to-End EVC Mobile Network RAN BS site Mobile Network RAN NC site Service Provider Core site UNI CEN UNI RAN CE Backhaul EVC RAN CE
Summary 1 2 3 4 5 5G is much more than a new wireless technology Multiple transport options can support 5G interfaces Application driven networks calls for network slicing LSO can facilitate orchestration of mobile and fixed networks MEF Services can run fully/partially over 5G
