SDN?

(per

(SDN)
is
an

Write Once, Run Anywhere

Base Service Set Description

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

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

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

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

Discovery L3 topology and local service discovery

Syslog events notification, Path tracing capabilities (ingress/egress and interface stats,
Utility next-hop info, etc.)
Debug capability, CLI extension which allows application to extend/integrate application’s
Developer CLIs with network element
