NBI Benefits
The benefits of the north-bound interface are as follows:
• Supports ISC services and inventory
• XML-based management interface
• Web-based
• Human-readable encoding
• Initial transport support is HTTP/SOAP
• API based on domain manager convergence API
API Approach
The API approach is as follows:
• Standards based encoding of management operations and payload.
• Layered approach combines need for rigor with flexibility (HTTP, SOAP, CIM Operations, Data
Model).
• Leverages XML technology and adds a management framework.
• Allows for polling-based management, event-based management, and synchronous, as well as
asynchronous services.
• Facilities for reliability: event numbering, tagging of requests.
• Facilities for security/RBAC.
• Standardized error semantics.
• Transport protocol agnostic.
Distributed Load Balancing
The major aspects of distributed load balancing in ISC are as follows:
• The Master server (which can be considered to be identical to the ISC Solaris workstation)
distributes jobs to processing servers via a sophisticated load-balancing algorithm.
