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

SDN Management Orchestration Model  In the Southbound direction (SDNC  NE/EMS)  Abstracts networking technology/protocol details from NetOS/SDN Controller  Provides vendor-independent programmability of network elements

 In the Northbound direction (SDNC Apps)  Provides network/service programmability (APIs) by software applications  Abstracts networking technology details from the applications

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 

Existing systems not flexible, service introduction can take months

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.
