following functional components:

Figure 1-1: Cajun A500 Software Architecture

U UNI Management Task (UNI mgmt task) manages the call control signaling 

messages. These messages pertain to the calls terminated locally in the switch 

control processor.

U Signaling Task sets up, maintains, and tears down connections used for control 

information within an Cajun A500 system. These connections are used both for 

Shortest Path First (SPF) messages and for connections enabling remote access to a 

Cajun A500 via ATM.

U Routing Task computes and maintains neighboring system (“neighbor”) 

connectivity and distributes the link state database.

U Switch Monitor Task manages overall Cajun A500 operation, including event 

handling and statistic gathering, as well as the Operations And Maintenance 

(OAM) of the PHY modules.

U Ethernet Driver initializes and monitors the Ethernet controller. 

U SAR Driver reassembles incoming traffic to the switch processor and segments 

outgoing traffic from the switch processor.
