SDN vs NFV
Function/ location separation
COTS hardware Vendor-independence
Initial focus on atomic network functions, but topology focus coming
Improved operational efficiency Standardized, open interfaces Dynamic chaining of network functions Centralized orchestration and management
Reduced power usage (elastic scalability)
SDN
NFV
Rapid service innovation
Control/ data plane separation
Consistent policy framework
Focus on network function connectivity (logical topologies)

Current OSS Landscape OSS Problem Statement OSS’s have limited or no technology abstraction Technology abstraction simplifies multi-vendor, multi-layer, multi-technology management
Difficult and time consuming to innovate Cost prohibitive to experiment with new types of services or customization of existing services
Provisioned Networks Limited Programmability and Service Elasticity
Managed Network Functions Limited Automation
Our Carrier’s cloud-centric OSSs must worldevolve requires to automation support this and newelasticity reality NFV and SDN Management Orchestration

Reinventing the OSS Network and DC are converging into a singular resource pool
Elasticity previously only available in DCs is migrating to the networking space Current OSSs not architected to deploy SDN technologies and NFV orchestration Carrier-grade service requirements still need to be met Service agility, service innovation as well as transformation of cost and operational models are drivers for change

Carrier Class Orchestration for SDN & NFV Prayson Pate Chief Technologist Overture Networks
OVERTURENETWORKS.COM
Carrier Orchestration is Different! Traditional orchestration (e.g. AWS CloudFormation) is focused on the data center.
26
Carrier Class Orchestration for SDN & NFV
Carrier SDN and NFV will be used to build carrier services across the network; orchestration must reflect additional requirements.
Resource Acquisition, Assignment & Span • In a data center, resources are all equivalent. • In an NFV network location matters • Span extends beyond data center to MEN and WAN Metro Datacenter Not just in here
All the same These resources are scarce, but lower latency
But also here Metro Network
Central Office Mini-Datacenter 27
Carrier Class Orchestration for SDN & NFV
Customer Site
Lifecycle and Work Flow • Critical to tie into higher-level systems • Could be OSS/BSS systems • Could be network applications • Programmable and transactional behavior on service activation • Reliability and status monitoring
28
Carrier Class Orchestration for SDN & NFV
Service Elasticity and Orchestrator Scalability • Services built using NFV must have VNF components that are elastic / horizontally scalable • Can’t be simple conversions of software to run on a server instead of an appliance
29
Carrier Class Orchestration for SDN & NFV
Orchestrator Multi-Tenancy • Wikipedia: “Multi-tenancy refers to a principle in software architecture where a single instance of the software runs on a server, serving multiple clientorganizations (tenants)” • Different from “virtualization where components are abstracted enabling each customer application to appear to run on a separate physical machine.” • Orchestrator multi-tenancy simplifies system design and integration into higher level systems.

Summary of Carrier Class Orchestration Aspect Resource Acquisition and Assignment Span of Control Lifecycle and Work Flow Service Assurance and Resilience
Data Center All resources are equivalent Within data center Controlled directly by user Coarse status monitoring
Elasticity, Scalability Current resources and Multi-tenancy are elastic 31
Carrier Class Orchestration for SDN & NFV
Carrier Class Location, latency and bandwidth matter Across metro area Tied into higher level systems Transactional behavior and fine status monitoring VNFs must be elastic and orchestrator multi-tenant
