The NSP architecture accommodates a wide variety of network management
functions and interworking capabilities. In addition to the core system
elements, an NSP deployment may include appliances, other products, and multiple
interfaces to in-house or third-party systems. For example, an NSP deployment
can include the NFM-P component and could integrate with one or more WaveSuite
product components.
The purchased feature packages, selected installation options, and operator
privilege levels (role-based access) determine which elements are available to
NSP users. For more information about installation options and feature packages,
see the NSP System Architecture Guide. For information
about access administration, see the NSP System Administrator Guide
.

Component
Description
Common nspOS components
The following components make up the base NSP
platform:
Login—grants SSO access to NSP, GUI clients,
and other resources
Entry point for NSP
NSP user authentication
Session Manager—tracks and manages SSO
sessions
REST API Gateway—acquires NSP REST API
tokens and locates specific NSP APIs
PKI service—generates and distributes TLS
artifacts for an NSP deployment
VSR-NRC
The Virtual Service Router - Network Resources Controller
(VSR-NRC) acts in a Virtual Network Function (VNF) capacity
to perform topology discovery. The VSR-NRC is based on the
SROS software, and implements the southbound protocols of
NSP's path control function, which consist of the Path
Computation Element (PCE) function, with PCEP, BGP-LS and
IGP protocols, and the OpenFlow Controller (OFC).
NFM-P
The NFM-P is a network management system that
functions as an NSP component. It simplifies routine
operations and allows the bulk provisioning of network
objects. The system is designed using industry standards
such as Java, XML/SOAP, REST, and WebDAV. The NFM-P
uses open-standard interfaces that allow the system to
interoperate with a variety of other network monitoring and
management systems.
WaveSuite
The WaveSuite product includes the WaveSuite Network
Operations Center (WS-NOC), an optical controller that can
be integrated with NSP to enable the discovery and
management of cross-domain links between IP and optical
networks
For more information about this type of integration, see
the NSP IP Optical Coordination Guide.
Data stores
The NSP uses various forms of persistent storage for
statistics and network data model information. In addition
to the NSP PostgreSQL database, an NSP deployment may
include an NSP auxiliary database, and for classic
management, an NFM-P database.
