1 Security Level: Management in a Software-Defined World Orchestration and Management of Network Functions Riccardo Guerzoni Huawei European Research Center Munich Krakow, May 2014 HUAWEI TECHNOLOGIES CO., LTD.

2 Future Carrier Networks: IT and Telco convergence Network Functions (BRAS, IMS, MME, ) become software modules that can run in virtualized data centers. M2M data SGSN POP1 POP2 Core HLR IMS AAA Big data Central office GGSN OTT service RNC POP3 BRAS MME Storage M2M data We are Current arriving carrier at a state networks where the need entire to infrastructure operate many can different be Data virtualized Center functions and flexibly and deal allocated with many to the hardware higher layer functions. components We need (each orchestration function is an to perform independent this assignment hardware efficiently. box). POP4 At the same time, network virtualization solutions emerge too! Slide 2 Riccardo Guerzoni NOMS 2014 Distinguished Experts Panel

3 Orchestration and Management In the NFV architectural framework proposal, the traditional O&M (Operation & Management) sub-systems evolves to an Orchestration and Management Plane: Service awareness: a VNF Manager monitors the evolving requirements of the Network Functions network elements Substrate heterogeneity awareness: a Virtualised Infrastructure Manager (VIM) handles the heterogeneity of the underlying resources and monitor them Efficient embedding Orchestration Closed-loop/autonomic: monitoring subsystem integrated in the SDN orchestration framework Slide 3 Riccardo Guerzoni NOMS 2014 Distinguished Experts Panel Service awareness Efficient Embedding Substrate heterogeneity awareness (Closed loop) From Network Functions virtualization (NFV); architectural framework, ETSI GS NFV 002 v1.1.1

They will involve the following components: Orchestrator Virtualised Infrastructure Managers (VIM) Management Platforms (CMP) Network Control Logics (NCL) s: User-to- s, -to- s, and network s Centralized allocation at abstract level -to- Third party VIM 3 rd party Proprietary CMPs Managemen t Platform (CMP) Open source CMPs Third party Management and Orchestration Own Management Platform (CMP) Own VNF Manager User-to- Virtual network requests Orchestration Own VIM Service request Abstract embedding solution Network Network Control Logic (NCL) Own SDN Products available R&D needed -to- Third party VIM 3 rd party Network Distributed Control Network Platforms Control Logic (NCL) HyperFlow but coordination of distributed Third controllers party needs further development SDN Slide 4 Riccardo Guerzoni NOMS 2014 Distinguished Experts Panel

5 Orchestration of virtually endless clouds One fundamental objection against centralized orchestration is scalability. Actually the Orchestrator does not need to be omniscient. In federated environments, cloud resources and services can be described, discovered and requested at abstract level, by means of to- s.
