3 NFV(Network Function Virtualization) NFV Network Function Virtualization has been widely experimented and deployed around the world. Operators are continuously moving traditional Network services to the NFV Cloud, in order to reduce its cost and accelerate service launching. Through the years, NFV has developed from concept and framework to field trail and real deployment. Cloud vepc vims vcpe vcdn vbras
4 China Mobile s Trip to NFV/SDN China Mobile announced its future network as NovoNet Based on NFV/SDN, NovoNet is a new network with shared virtual resources and agile network structure. NovoNet provides network users with scalable resources and open API to utilize China Mobile began its vims trail in 4 provinces since 2015, NB-IoT trail in 6 provinces in 2016 China Mobile began its NovoNet Experiment network since This is a grand new network built for experiments and testing of NFV/SDN. The network currently includes 4 provinces. Multiple services, including NB-IoT, vbras, scpe, E-BoD are tested in this network China Mobile Open NFV Testlab Open NFV lab membership announcement Launching NovoNet Experiment Network Founding member for OPNFV NovoNet white paper Open NFV lab membership announcement Founding member of Open-O & ONAP NovoNet Experiment Network Phase NovoNet Experiment Network Phase 2 4
5 China Mobile Future Network Architecture China Mobile structures its NFV Cloud into TICs (Telecom Integrated Cloud) TIC is a standard unit, with unified hardware and software infrastructure. Multiple VNF services are deployed in TICs TICs are categorized into Core TIC and Edge TIC, in which core TIC mainly supports control plane services, and Edge TIC is for forwarding plane services ONAP Core TIC Core TIC Core TIC 50~100 SDN-Ctrl Edge TIC Edge TIC 1000~3000 Edge TIC Edge TIC Edge TIC AP 1,000,000 enodeb Mobile Access AP Residential User PTN Enterprise User

SG design OSS VNFs Hypervisor NFVO VNFM OpenStack Unified Hardware Unified hardware design with limited number of models suitable for different category of services. Hareware SDN-Ctrl Design Template 4 TIC design templates to carry VNF services of different kind, including: Template for Control plane services, stressing on compute capability Template for Data plane services, stressing on data forwarding capability Template for Edge services, stressing on low cost and light weight Template for Storage services, stressing on storage capability Key Features for TIC: Standard unit, Template-based, Easy to copy 6

8 China Mobile NovoNet Experiment Network Since 2016, China Mobile is building its Novonet Experiment Network in 4 Provinces. 7 DC sites are included in the network, 14 TICs are constructed VNFs include vepc for NB-IoT, vbras, vcpe, and E-BoD 9 virtual infrastructure vendors, 5 VNF vendors, 3 orchestrator vendors, 4 SDN vendors, are included in the network In Phase 1, most of the integration and testing work are done manually, which cost us more than 9 months to construct the 14 TICs. In phase 2, we plan to utilize the automatic system so as to significantly reduce complexity and man s labor Beijing Shanghai Zhejiang Guangdong

10 Automatic On-boarding system: Weeks to Minutes Automatic On-boarding system is crucial for future network integration and large scale deployment The integration of TIC includes components from multiple vendors with complicated process. Manual integration leads to huge workload, and is almost impossible to repeat. Different from traditional network made of bunch of hardware, future software infrastructure on-boarding of TIC requires functional, performance and availability testing before launching An automatic integration and on-boarding system provide standard process and tools for integration and on-boarding testing for multiple vendors. Making the whole TIC easy to copy and re-integrated Multiple Vendors Impossible for manual work Software integration Standard on-boarding test Rapid construction NFV Host os installation TIC infrastructure deployment VNF deployment On Boarding Test Hand over NFV 10
