System components

Overview

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 and the WS-NOC product. .

The purchased feature packages, selected installation options, and operator privilege levels determine which elements are available to network operators.

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.

WS-NOC

The WaveSuite Network Operations Center (WS-NOC) is a standalone optical network management product that can also function as an NSP component. The WS-NOC provides end-to-end optical management functions that include service provisioning over multi-technology optical transport networks such as SDH/SONET, carrier Ethernet, WDM, ROADM, OTN, and packet. Browser-based fault management applications reduce the time and cost of network and service assurance operations, and an API enables OSS integration.

For more information about the WS-NOC, see the WS-NOC Getting Started 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.
