Network Services Platform functional overview

The Nokia Network Services Platform (NSP) is a group of interoperating network management modules that provide comprehensive end-to-end management of a wide range of network domains and topologies.

The Nokia NSP Network Functions Manager - Packet (NSP NFM-P) is used to discover, configure, and manage the nodes and related cellular domains. The NSP NFM-P provides the following specific functions. (See the NSP NFM-P User Guide for more information.)

• creates and manages the cellular domains. A cellular domain is a group of nodes where each node in the group connects to the same head-end nodes, shares the same deployment modes of operation, and is part of the same NGE domain. For more information about deployment modes of operation, see the PDN router interfaces section of this guide.

• drives the ADP-Hm process for each new node to be discovered in a cellular domain. For static cellular interface IP and dynamic modes of operation, the NSP NFM-P creates a management VPRN service for in-band management of each node.

• manually adds or removes nodes to and from cellular domains

• supports the XML input lists of the SIM IMSI values that are expected to participate in the cellular domain and initiate the ADP-Hm process within the cellular domain. These lists include the SIM information and optionally, the system IP for node boot-strap process.

• creates a security association between the SIM, IMEI, and the chassis identifier for each node being managed such that unexpected changes are flagged as potential security violations to the operator.

• supports a configurable NSP NFM-P polling interval for nodes. Configurable polling is intended to minimize traffic between the NSP NFM-P and a large-scale deployment of nodes. To that end, the NSP NFM-P also polls the status of the BGP sessions between head-end nodes and the nodes in the cellular domain in order to monitor the reachability and status of the nodes in the cellular domain.
