Nokia Network Services Platform
Release 17
Carrier SDN and network management for IP/MPLS, Carrier Ethernet and
optical networks. The Nokia Network Services Platform (NSP) is the first carrier
software-defined networking (SDN) platform that unifies service automation,
network optimization and dynamic assurance so that network operators can
deliver on-demand network services efficiently, profitably and with scalability.
The Nokia NSP provides operators with an
abstracted and simplified way to define, provision
and activate network services across networks
that can span multiple layers (Layer 0 to Layer 3),
multi-technology services and physical/ virtual
infrastructure, as well as equipment from multiple
vendors.
With the Nokia NSP, service instantiation is
intelligent, ensuring that services are mapped to
the best available IP and optical network paths. With
optimization criteria and constraints specified at
service creation, operators can be confident that
provisioned services are placed on optimal paths,
whether to achieve low latency, cost or utilization,
and with service requirements for bandwidth
being met on demand. The NSP also continuously
adapts and optimizes the network in real time
using flow redirection and self-tuned adaptive
routing. By intelligently adapting the network to
real-time changes in demand and traffic patterns,
NSP enables operators to get more out of existing
network assets while keeping service quality and
network efficiency high.
1
The Nokia NSP extends assurance, such as integrated
OAM tests and network and service supervision,
to SDN services so operators can move from trial to
large-scale deployments. Extending SDN automation
to assurance functions ensures ongoing optimization
for meeting service level agreements (SLAs)
(e.g., latency), improves service/network health
and delivers higher network performance — without
manual intervention.

How the Nokia NSP works
The NSP addresses the dynamic connectivity needs
of cloud applications through on-demand creation,
maintenance and removal of IP/MPLS, Ethernet and
optical network services and resources. It uses a
powerful policy engine and abstracted, standardsbased service models to quickly and efficiently
create network services. An intelligent, networkaware service connection manager optimizes the
mapping of service connections to network tunnels
and resources in real-time.
With simple REST/RESTCONF Application
Programming Interfaces (APIs), IT and Operations
Support Systems (OSSs) and service orchestrators
can integrate with the NSP. This set of NSP northbound APIs enables access to abstracted models
that hide service provisioning complexity and
enable assurance for the Carrier SDN era. The NSP
Connected Partner Program certifies third-party
application interoperability through the NSP northbound API for leading industry IT/OSS vendors.
2
With multiple southbound device management
protocols, the NSP is able to deploy services, paths
and other network resources over IP, optical or
Carrier Ethernet network equipment and across
equipment from multiple vendors.
Product components
The NSP consists of seamlessly integrated
components: the Network Services Director (NSD)
for service automation, various Network Resources
Controller (NRC) modules for IP and optical PCEs and
flow control, and Network Functions Manager (NFM)
modules for IP/MPLS, Carrier Ethernet and optical
network management. All modules present the
option of adding Assurance and Analytics functions
and applications. Modules share a common set of
REST/RESTCONF APIs. (See Figure 1.)

Network Services Director
The Network Services Director (NSD) is the network
service fulfillment module of the NSP. It automates
IP/MPLS, Carrier Ethernet and optical service
provisioning by mapping abstract service definitions
to detailed service templates using operatordefined policies. It also provides provisioning for
complex multi-technology services across multidomain networks.
The NSD maintains abstracted service models
that are “Yet Another Next Generation” (YANG)
standards-based and maps these to devicespecific models that are normalized for multivendor
provisioning transparency.
A key benefit of the NSD provisioning is that it is
network-aware and manages a centralized database
of service connection resources (tracking tunnel
bandwidth). This means that as it provisions
services, it performs an inline optimal path selection
through an intelligent path search within its
database, which finds available paths that will best
meet required bandwidth, span, latency, cost, path
diversity and other constraints. Through tracking
link state in its centralized database, including link
utilization, the NSD uses policies to direct incoming
service connection requests to tunnels/paths that
use less-utilized links. In this way, the NSD can avoid
potential congestion.
3
The NSD allows operators to customize the binding
of service connections to tunnels/paths by letting
them define service-specific policies.
If there is no service connection path that meets
the specified requirements (i.e., if one does
not currently exist or if none have the required
characteristics), then through policy the NSD can
leverage the NRC to establish a new path.
The NSD works in conjunction with the NSP
Assurance and Analytics function for use-cases such
as IP/optical network-aware provisioning automation
with service validation, and bandwidth-on-demand
for IP/optical services with Link Aggregation Group
(LAG) re-sizing. (See Assurance and Analytics
section, Figures 2 and 3.)
Network Resource Controller
The Network Resource Controller (NRC) performs
multi-domain and multi-layer path computations
across IP/MPLS, optical or IP/optical networks.
The NRC serves path connection requests from
the NSD, OSSs and orchestration systems, and
physical/virtual network elements. Because the
NRC is centralized, it has the full IP/optical network
view required to calculate the optimal path for
any combination of business objectives (e.g.,
lowest cost) and technical constraints (e.g., exact
bandwidth or latency required).
Data Sheet
Nokia Network Services Platform
The NRC is standards-based on a stateful PCE
architecture. It employs various path optimization
algorithms to ensure the best path placement for
services and load-balancing for path distribution
across the network. This includes the Nokia Bell
Labs Self-Tuned Adaptive Routing (STAR) algorithm
which is proven to be able to place 24 percent more
paths on the network than with present modes of
operation using Constrained Shortest Path First
(CSPF).
The NRC leverages these algorithms to release
stranded bandwidth, to intelligently distribute
tunnels/paths across the network so that operators
can get more from existing networks, and to
eliminate the need for manual stitching of inter-area
and IP/optical paths.
The NRC-F addresses several use cases, including:
• Congestion resolution with flow re-direction to
alternate paths (See Assurance and Analytics
section, Figures 4 and 5)
• VIP-source subnet-based steering and VIP link
management
• Per-Autonomous System (AS)-based traffic
optimization
• Egress peer engineering
• Distributed denial of service (DDoS) mitigation

Network Resource Controller – X
The NRC-X controls hybrid inter-domain and interlayer (IP/optical) path calculation and optimization. It
functions across multiple routing domains, multiple
transport domains or a combination of routing and
transport domains. It serves as a parent to the
NRC-P and NRC-T when required to dynamically
calculate optimal paths through hybrid IP/optical
networks. Additionally, it serves as a parent to thirdparty SDN controllers and PCEs.
Network Functions Manager
The Network Functions Manager (NFM) performs
comprehensive network management for
network infrastructure deployment, provisioning,
maintenance, statistics collection, proactive OAM
testing, troubleshooting and OSS mediation. The
NFM provides base fault, configuration, accounting,
performance and security (FCAPS) management
with many advanced extensions for network
deployment automation, service templates and
assurance.
The NFM is comprised of two modules:
• Network Functions Manager – P (NFM-P), and
• Network Functions Manager – T (NFM-T)
Network Functions Manager – P
The NFM-P enables IP network and service
management across all domains of IP/MPLS
and Carrier Ethernet networks across access,
aggregation, metro and core. It also delivers unified
operations, whether network services are running in
a virtualized environment or on specialized hardware
platforms. This includes mobile management from
backhaul to packet core (including the latest Nokia
cloud-based Evolved Packet Core [EPC] solution),
as well as IP/microwave transmission.
The NFM-P provides an advanced scripting
framework to enable customized programmatic
control for automation of network deployment,
audits and bulk maintenance changes. Its golden
configuration and snapshots application bring
enhanced integrity to network deployment that

reduces mis-configurations. It provides multivendor
route analytics through its Control Plane Assurance
Manager (CPAM) application. The NFM-P also
delivers an integrated carrier-grade Virtual Network
Functions VNF manager (VNFM) for Nokia IP Routing
and EPC VNFs which fits into ETSI NFV management
and orchestration (MANO) environments leveraging
OpenStack.
Network Functions Manager – T
The NFM-T centralizes and consolidates multiple
functions for the management of optical networks
from access to metro to core. The NFM-T allows
network operations staff to efficiently plan, deploy
and manage the optical network over its complete
life cycle. It also provides element, network and
service management that supports multiple optical
technologies, services and network sizes.
The NFM-T provides common optical management
for end-to-end operations. This includes service
provisioning over multi-technology optical
transport networks (SDH/SONET, Carrier Ethernet,
WDM, reconfigurable optical add-drop multiplexer
(ROADM), OTN and packet). Fault management
web apps reduce the time and cost of network and
service assurance operations. A common northbound API enables OSS integration.
Assurance and Analytics
Comprehensive network and service assurance
from the NSP’s Analytics and Assurance functions
are an integrated option available for all NSP
modules. These integrated capabilities are required
to ensure effective realization of many carrier SDN
use cases. To bring carrier SDN from lab trials
to live deployment, assurance and analytics with
automated actions and abstracted day-to-day
operations visibility will be critical.
The NSP Assurance and Analytics functions are
needed to ensure that operations keep pace by
driving and automating smarter services placement
on network resources so that requested SLAs can
be honored.

Traditionally, once a service was instantiated,
operators continuously surveyed alarms/KPIs
and took manual actions (or, at best, userdriven, partially automated actions) to continue
safeguarding SLAs. As network service delivery
becomes more dynamic and network demand and
traffic patterns become less static and predictable,
operators need a higher level of network and service
supervision visibility and automated control. This is
required in order to keep up with the higher rate of
changes to the network and services.
The NSP Assurance and Analytics functions utilize
automation from the SDN control layer so they
can keep up with the dynamic provisioning and
optimization of SDN networks. These closed-loop
assurance capabilities leverage KPIs and analytics
to drive automated policy-based optimization and
OAM actions to improve overall service health and
network efficiency from initial delivery to day-to-day
operations.
An example is using NSD for service provisioning to
enable IP/optical network-aware path placement
automation with service validation. (See Figure 2.)
6
In addition, service/network supervision visibility is
needed for operators to efficiently stay in step with
network events and provide the correlation needed
to perform intelligent root-cause and services
impact analysis.
Because dynamic assurance is only as good as the
data that feeds it, NSP Assurance and Analytics
functions include policy triggers that encompass
analysis/correlations from both IP and optical layers,
and from both physical and virtual domains.
For example, with the NSP Assurance and Analytics
functions that monitor link utilization, a service
managed in NSD can be set up to be monitored
and will trigger (through a raised threshold alert)
the dynamic resize of bandwidth using the LAG
connectivity in an IP/MPLS or Carrier Ethernet
network. And for integrated IP/optical network
services, this can in turn re-size capacity for the
underlying optical transport service through adding
optical channels. (See Figure 3.) These monitored
“LAG services” are then resized down when the high
utilization across the service subsides.

*Assurance & Analytics may be provided with NFM or NSD or NRC modules.
NSP Assurance and Analytics also feeds the NSP
NRC modules with the KPIs needed to deliver
intelligent steering and load-balancing of traffic.
KPIs enable analytics-driven policies that automate
actions to ensure critical SLAs are met and that
optimal use of IP/optical assets is made. To avoid
network congestion, traffic flows can be redirected,
new multi-layer paths established, or existing paths
resized dynamically, as dictated by policy. Dynamic
tuning of network resources, such as re-directing
traffic flows and services onto alternate paths, will
also free up assets to generate additional revenue
for carriers.
NRC-F works in conjunction with the NSP’s
Assurance and Analytics functions that collect link
utilization and flow statistics and automatically
monitors for congestion. When a traffic precongestion situation is detected, the NRC-F steers
traffic flows (according to defined policy) onto
alternate paths that avoid congestion – well before
service quality is impacted. (See Figure 4.)

Multi-tenancy for Network-as-a-Service (NaaS)
The NSP enables the creation of virtual network
slices, also known as network partitioning, allowing
the independent existence of multiple tenants on
a single physical infrastructure. Each enterprise
on the operator’s network has its own virtual
network, distinct, secure and independent of other
enterprises’ services and of the operator’s own
production network.
8
The enterprise has complete end-to-end visibility
of its services and the ability to monitor SLAs,
turn up new services, change bandwidth between
sites, re-route services between sites and rapidly
adapt to changing service requirements or network
conditions. The operator retains a global view of the
network and the ability to manage and monitor all
elements.
