The Performance Routing - Application Interface feature introduces support for an Optimized Edge 
Routing (OER) application interface. The application interface defines the mode of communication and 
messaging between applications and the network for the purpose of optimizing the traffic associated with 
the applications. A provider must be registered with an OER master controller before the application can 
interface with OER. Host devices in the provider network running an application that communicates with 
OER using the application interface must also be configured at an OER master controller with an IP 
address and key chain password. After registration, a host device in the provider network can initiate a 
session with an OER master controller. When a provider application initiates a session with an OER 
master controller, a session ID number is allocated to the session. After a session is established, the 
application can send a request for reports containing performance numbers for traffic classes, 
dynamically create policies to influence the existing traffic classes, or specify new traffic class criteria. 
The application interface provides an automated method for networks to be aware of applications and 
provides application-aware performance routing.

Configuration information is included in the “Setting Up OER Network Components” chapter of the
