NSP network mediation

Description

The NSP interacts with the network using MDM, and through optional classic SNMP management using protocol providers such as the VSR-NRC. NSP mediation provides:

• network data access

• object provisioning and modification mechanisms

• network change and event notifications

Note: The NSP supports NE mediation using IPv4 and IPv6 concurrently; see “IP version support” in the NSP Installation and Upgrade Guide for information.

The NSP includes the following network mediation mechanisms and components:

• MDM, in a deployment that includes Pluggable Network Adaptation, which provides mediation services for:

  • devices managed using YANG model-based interfaces

  • multi-vendor IP devices managed using SNMP

• NSP Flow Collectors, which collect AA Cflowd or System Cflowd statistics directly from NEs

• NFM-P, in a classic management deployment for legacy SNMP management

• VSR-NRC, which mediates with IP NEs for PCE-PCEP and OpenFlow communication

• WS-NOC, for optical transport network mediation

Classic management

The NFM-P provides role-based FCAPS functions for classically managed networks. In addition to managing Nokia devices, you can obtain NFM-P adaptors for managing third-party equipment.

LLDP link discovery

The NSP has an internal LLDP service that discovers MDM-managed LLDP links. The service is deployed by default and no user configuration is required, but all appropriate MDM LLDP v2 adaptors for your NEs must be configured on your system.

Note: Because MDM adaptors may not support events on link objects, there may be a delay of up to 60 minutes before link updates appear in the NSP. Any other updates to the LLDP state that are not triggered by the port can take up to 24 hours to appear in NSP.
