System design

Development methodology

The NSP architecture incorporates design considerations that include:

• open standards that promote interworking and integration with in-house or third-party systems; see Appendix A, NSP technology standards for information

• flexible internal model that accommodates product evolution

• deployment agility for adaptation to changing network scope or complexity

• programmability for dynamic management of network operations

• SSO access

• IPv4 and IPv6 support on internal, external, and mediation interfaces

• cloud-native distributed processing for efficiency and horizontal scalability

• fault-tolerance safeguards that include local and geographic redundancy

• stringent internal security among components

• highly secure local and remote client access

Core system elements

The various components of the modular NSP architecture work together as a customized management solution designed to meet your current and changing network or business requirements. Components and functions can be readily added, updated, or removed, as required.

Depending on the installation options that you choose, ancillary components in an NSP system may provide the following:

• graphical user interfaces

• public APIs

• management domain or business logic

• mediation services

The NSP is designed to interface or integrate with external systems such as the following:

• remote authentication agents for user access

• other EMS or network controllers

The following figure shows an abstract representation of the NSP services and interfaces.
