* "Due to small parts(Booleans), this code is not suitable for"

|
|
* Purpose: This code-file defines the SUA management handling functions for
|
|
* sending and receiving Application Server Process(ASP) messages:
|
|
* - send a ASP-UP msg to remote node
|
|
* - send a ASP-UP ACKnowledge msg to remote node
|
|
* - send a ASP-DOWN ACKnowledge msg to remote node
|
|
* - send a Hearbeat msg to remote node
|
|
* - send a Heartbeat ACKnowledge msg to remote node
|
|
* - send a ASP-ACTIVE msg to remote node
|
|
* - send a ASP-ACTIVE ACKnowledge msg to remote node
|
|
* - send a ASP-INactive Acknowledge msg to remote node
|
|
* - send a NOTIFY msg to remote node
|
|
* - Receive/process ASP UP msg
|
|
* - Receive/process ASP UP ACKnowladge msg
|
|
* - Receive/process ASP DOWN msg
|
|
* - Receive/process ASP DOWN ACKnowledge msg
|
|
* - Receive/process Heartbeat msg
|
|
* - Receive/process Heartbeat ACKnowledge msg
|
|
* - Receive/process ASP ACTIVE msg
|
|
* - Receive/process ASP ACTIVE ACKnowladge msg
|
|
* - Receive/process ASP INactive msg
|
|
* - Receive/process ASP INactive ACKnowledge msg
