LR Name Server Tree
The name hierarchy for the Cisco CRS-1 Series router is shown in Figure 11-1. The root naming context
identifies the particular logical router (LR) on which the Name Server is running. Within the root context
is the list of object references that components within the LR have exported.

Event Notifications and Alarms
The CORBA Notification Service is used to deliver events asynchronously to registered clients. Each LR
exports one structured notification channel for alarms called “AlarmChannel.” This channel is exported
to the Name Server as shown in the Name Server tree for the LR. Client applications can obtain the
AlarmChannel IOR and use its standard IDL interface to register interest in events and alarms based on
filters.
CORBA Notification Structure
Client applications can receive asynchronous events through the CORBA Notification Service. The
alarm notifications are in the form of CORBA structured events where the fixed header consists of the
following definitions:
• Domain = LR DNS Name
• Type = alarm
• Instance = Event ID
