Service

Dependency

 

 

Layered Enhanced Accelerated

Availability Service uses LEAP for portability. It uses

Portability (LEAP)

the memory manager, timers, encode-decode utility,

 

and handle manager services provided by LEAP.

 

 

Message Distribution Service (MDS)

Interaction between the subparts of AvSv takes place

 

using MDS messaging.

 

 

Distributed Tracing Service (DTSv)

Availability Service uses DTSv to log debug messages

 

and to report informational events.

 

 

System Resource Monitoring Service

Availability Service uses SRMSv for passive health

(SRMSv)

monitoring of components.

 

 

Event Distribution Service (EDSv)

Availability Service uses EDSv to receive all fault

 

events related to resources it manages.

 

 

Hardware Interface Service (HISv)

AvM uses HISv to issue hardware platform (HPL)

 

commands for managing nodes.

 

 

Management Access Service (MASv)

AvD and AvM use MASv to manage the MIB objects

 

defined in the AvSv MIBs.

 

 

Message Based Checkpoint Service

The active AvD uses MBCSv to checkpoint the state

(MBCSv)

information with a standby AvD.
