•MPLS VPN Service

•Inventory

•IPsec VPN Service

•FireWall Service

•NAT Service

•SLA

•Deployment Flow Engine

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.
