  11. Case A: MNO(L) Selected E2E new build L3 IPRAN for 5G 2011:built IPRAN for LTE 2016:Merged BA and MCOT 2018~2019:E2E new build 5G Backhaul EPC EPC/vEPC RBA RBA RBA IP Core IP Core IP Core N*100GE MAB N*10GE BA MAB N*10GE MCOT MINT MINT MINT N*100GE N*10GE N*10GE MRT MRT MRT ACOT vEPC MEC/gNB-CU ACOT ART 100GE 10GE 10GE ART ART LTE eNB LTE eNB IPTV 5G gNB • Why MNO(L) build new IPRAN for 5G? (Challenges): • Bandwidth requirement: in LTE backhaul metro, no slots for bandwidth expansion and access box can not support 100GE; • Network Architecture limitation: Big L2 architecture, hard to meet future 5G services; • Complex service deployment and O&AM: Native eth + L2 VPLS + Native L3 solution, totally Command line based O&M.

  12. Case B: MNO(S) IP-RAN Evolution, Partially new Built 2015: Built L3 IPRAN 2017: merged P and PE 2019: build new 5G IPRAN NE9000: 80T PE+P PE+P PE PE IP Core IP Core P P N*100GE PE+P PE+P N*10GE P P 5G IPRAN NE40E-X16A:32T PE PE NE40E-X8A: 3.2T IBC IBC IBR IBR IBC IBC LTE IPRAN LTE IPRAN N*100GE N*10GE N*10GE IBR IBR IBR IBR IBR IBR 100GE Ring IBRR 10GE Ring IBRR 10GE Ring NE40E-M2K: 910G IBRR IBRR IBRR NE40E-M2E: 80G IBRR IBRR IBRR IBRR IBRR IBRR IBRR 5G gNB LTE eNB LTE eNB • Key Challenges to MNO(S): • Bandwidth Requirement: similar to MNO(L). MNO(S)will build new 5G IPRAN first, and merge LTE service to 5G IPRAN after 2021; • O&M: CMD line based, inefficiently;MNO(S)want to deploy self-developed SDN platform interworking with NCE for automatic multi-vendor devices management.

  13. Case C: MNO(3) Builds 5G-ready Transport Network After unlimited packages are provisioned, traffic volume keeps increasing significantly 5G-Ready ultra broadband, smoothly evolved protocols, and gradual introduction of intelligent features • Unit:Gbps • Unified O&M • a CAGR of around 40% NCE-Super • E2E automaticTraffic Optimization • SDN third-party integration • IP Crystal network Planning NCE-IP 3rd Party IPv6 MPLS SR-TE AGG Core PE CSG Pre-AGG • Ultra Broadband • New-built Network • 10GE to Site • 100GE/400GE in AGG./CORE • E2E network slicing L#VPN No infrastructure and continuously rising rental costs and other operating expenses Day1 SR-TE SR-TE L3VPN L3VPN • Programmable Arch.

  21. Challenges Faced by Operators on Cloud LL Challenge 1 : Provisioning is complicated, long TTM, high cost Enterprises want hybrid cloud, want to use different application on different public cloud Operators provide connectivity to multiple cloud for enterprises, the period of network planning is long, the related manual configuration is complex. It can not respond the rapid demand of cloud service Multiple Cloud Operators’ Network Self-owned cloud CGW Enterprise Users Ethernet L2 Exchange Network MPLS L3VPN OTN … … • Challenge 2:Hard to O&M • Without visualization system to monitor the private line to cloud, hard to trouble-shooting • Enterprises want BOD (bandwidth on demand), manual configuration is impossible mission
