9 What Does It Mean to Be NFV? from Early Virtualization to Efficient Cloudification monolithic software VNF NVF decomposition dedicated COTS COTS NFVI open/shared infrastructure manual operations flexible automation
Separating Signaling and Media SBCs have typically been proprietary purpose-built solutions and heavy network processing requirements around transcoding and media processing Managing signaling load as SIP messages increase significantly within VoLTE networks > Massive scalability and performance requirements > High performance requirements with networkintensive loads in the media plane 10

12 Align SBC VNF With Best-practices for Cloud Architectures Drivers - Application flexible deployment and scaling (efficient use of available compute resources) - Application QoS and resilience - Application performances and capacity (also depends on the capabilities of the cloud infrastructure) HW appliance SBC - Reuse common set of services centrally managed and leverage state of the art technologies e.g. database Architectural Guidelines - Decompose into discrete functions with a micro-services mindset and ability to scale signaling and media functions independently Firewall aas Load balancer aas OAM VNFC Peering VNFC Media VNFC Data-less SBC VNFs Session data Subscriber data - Remove state and subscriber data from SBC application logic - Use standard API s to interface with XaaS - Maximize use of commoditized and open source modules for commonly used functions - Drive toward N+K Hot so all resources are being used Openstack cloud VMware cloud LXC cloud Other cloud - SBC application must be agnostic to how packets are delivered to the function - Define setup and configuration of technologies at instantiation
Re-architecting SBC for Migration to the Cloud: Principles Infrastructure agnostic Lifecycle management automation VNF decomposition (micro services) Flexible resiliency Stateless design Cloud-ready SBC Optimized media performances Support XaaS Pricing flexibility Different aspects to correctly architect and manage VNFs in a cloud infrastructure one size does not fit all! 13
