Diverse Programmability Requirements Across Segments (Automation & Programmability)

Scalable Multi-Tenancy

Network Flow Management

Network “Slicing”

Agile Service Delivery

So#ware defined networking (SDN) is an approach to building computer networks that separates and

abstracts elements of these systems

What is SDN? (per Wikipedia defini>on)

Control and Data Plane resides within Physical Device

In other words…

In the SDN paradigm, not all processing happens inside the same

device

Base Service Set Description

Data Path Provides packet delivery service to application: Copy, Punt, Inject

Policy Provides filtering (NBAR, ACL), classification (Class-maps, Policy-maps), actions (Marking, Policing, Queuing, Copy, Punt) and applying policies to interfaces on network elements

Routing Read RIB routes, add/remove routes, receive RIB notifications

Element Get element properties, CPU/memory statistics, network interfaces, element and interface events

Discovery L3 topology and local service discovery

Utility Syslog events notification, Path tracing capabilities (ingress/egress and interface stats, next-hop info, etc.)

Developer Debug capability, CLI extension which allows application to extend/integrate application’s CLIs with network element
