2 NSD and NRC modules

2.1 Overview

2.1.1 Introduction

The NSD and NRC modules of the NSP form a carrier software-defined networking (SDN) platform
that unifies service automation with network optimization, allowing network operators to deliver on-
demand network services cost-effectively and with scalability. Using these modules, operator can
define, provision, and activate network services across networks that span multiple layers (Layer 0
to Layer 3), services, and infrastructures (physical and virtual), as well as equipment from multiple
vendors. The NSD and NRC modules are scalable, and based on standard protocols with multiple
APIs.

The NSD and NRC modules act as bridge between the IT and network worlds. Upstream, they
provide standard APIs, object models, and abstractions to IT OSS applications. Downstream, they
manage network complexity by translating simple service requests into commands that program
physical and virtual network elements. This is done automatically, across both IP and optical
boundaries, and across multiple network vendors.

The following NSP and NRC modules are available for deployment as part of NSP in this release:
• Network Resource Controller — Flow — flow-based traffic steering
• Network Resource Controller — Packet (NRC-P) — MPLS path computation
• Network Resource Controller — Transport (NRC-T) — Optical path computation
• Network Resource Controller — Cross Domain (NRC-X) — Multi-layer correlation and multi-

domain coordination
• Network Services Director (NSD) — multi-vendor service fulfillment

Note: The NRC-X module and the corresponding Cross Domain Coordination application are
beta quality in this release.

The following figure shows a typical NSP deployment on virtual machines, with all NSD and NRC
modules included:

Release 17.12 Nokia – Proprietary and Confidential
December 2017 Use pursuant to applicable agreements

Issue 1 3HE-12072-AAAD-TQZZA 17

Overview NSD | NRC

Service automation

With the Network Services Director (NSD), OSS and IT applications are able to quickly
communicate their service requests using simplified, abstract APIs and object models. Operators
can also use policies to abstract their service placement intentions. For instance, a policy can be
used to map a service request to the network path with the lowest latency, a specific amount of
available bandwidth, and the least amount of congestion. If such a path is not available, the policy
can dictate mapping to a secondary path and switch to a suitable path when the desired conditions
have been met. If no suitable path is available, the policy can communicate this, or request a new
path to be computed by passing the associated parameters to the network optimization modules. To
complete service provisioning, the NSP handles the complex task of provisioning the operator's
multi-domain, multi-vendor network using SDN standards such as NetConf/Yang, OpenFlow,
PCE-P, and other protocols. In the case of legacy equipment, traditional mechanisms such as CLI
are used. This functionality is available from the Service Fulfillment application.

For more information, see 2.6 “NSD” (p. 40) and 2.4 “NRC-T” (p. 32).

Network optimization

The Network Resource Controller (NRC) modules centralize path computation and network
optimization in order to leverage a whole network view and make the best possible decision for
each request. For IP, this is done with a packet PCE. For Optical, this is done with a transport PCE.

Use pursuant to applicable agreements December 2017

18 3HE-12072-AAAD-TQZZA Issue 1

NSD | NRC Overview

For hybrid IP/Optical network, this is done with hierarchical PCEs. The latter for the simultaneous
provisioning of services across IP and Optical networks. Centralized path computation elements are
opened up to application and policy control, and to specialized algorithms. For instance, path
computation can be enhanced to take link congestion into account. You can also make better use of
your network assets and keep SLAs high by using KPIs and metrics to trigger optimization policies.
You can also do all this in a multi-tenant way where each tenant – or in essence, each business unit
- has their own abstracted view of the network and their own policies for maintaining service quality
and assurance.

For more information, see:
• 2.2 “NRC-F” (p. 21)
• 2.3 “NRC-P” (p. 25)
• 2.5 “NRC-X” (p. 38)

External applications notifications

The NSD and NRC modules provide a base platform for asynchronous event notifications to

external applications, such as orchestrators. These notifications are transported using HTTP Server
Side Events (SSE) according to the IETF RESTCONF protocol specification. Notifications are
defined in the YANG modeling language and encoded in JSON format. This base platform is used
by the modules to realize different types of notifications.

Clients of the modules' northbound interface (NBI) receive notifications whenever the state of a
managed object changes. This simplifies synchronization with the modules, as periodic polling of
the REST API is avoided. Notifications are provided for the operational and administrative status of
services and endpoints.

Note: By default, a maximum of 10 users can be subscribed to these notifications. This
amount can be modified from the configuration file in the directory where the NSD and NRC
installer was extracted. See the NSP NSD and NRC Installation and Upgrade Guide for more
information.

2.1.2 Applications

The NSD and NRC modules also provide functionality using browser-based applications. Each of
these applications use the standard NSD and NRC REST security mechanisms for authentication
and authorization, so every request sent to the server contains the provided session key. All
applications are HTML5–based, and supported on the latest version of Google Chrome. Use the
following URL to access the NSP dashboard, from which you can launch all supported applications:

https://server

Where server is the hostname or IP address of your installed NSD and NRC server.

For more information about the individual applications, see Chapter 3, “Applications overview”.

Issue 1 3HE-12072-AAAD-TQZZA 19

Overview NSD | NRC

2.1.3 NSD and NRC REST APIs

The NSD and NRC modules provide northbound RESTful APIs that expose a simplified view of the
network. This view is constructed from the internal model, which is stored in the Topology
Database. The APIs support queries, service creation requests, and many additional functions.

To view and interact with the APIs online, go to one of the following URLs:
• https://server:8543/sdn/doc
• https://server:8543/task-scheduler/doc
Where server is the hostname or IP address of your installed NSD and NRC server.

2.1.4 Additional components

The NSD and NRC modules rely on the following additional components to provide end-to-end
functionality:

• Topology Database — The Topology Database contains a representation of the network in the
form of a highly abstract, multi-layer graph. The graph is stored in a Neo4j database.

• Network Mediation — The Network Mediation component is responsible for populating the
Topology Database with the network information and for deployment of network configuration. It
is comprised of the generic plugin framework, as well as the mediation plugins that operate
inside these. Plugins may interact with the network through Element Manager Systems (EMS)
such as the NFM-P, and/or standard communication protocols such as PCEP, BGP-LS, or

OpenFlow. The NSD and NRC modules support the deployment of network tunnels, services,
and, potentially, tunnels.

• Service Connection Manager — The Service Connection Manager is responsible for finding
appropriate tunnels for services.

• Algorithm Framework — The Algorithm Framework is the component that provides a run time
environment for the invocation and execution of both routing and optimization algorithms.

• Network Deployment — The NSD and NRC modules support the deployment of network tunnels,
services, and, potentially, tunnels. This means that some plugins and mediation framework may
support the “push to the network” function that involves the mapping and conversion of the
Topology Database entities to the network objects.

• Security — Security is the component that handles sign-in, encryption, logging of operator
actions, and network events.

• Relational Database — A PostgreSQL database that contains all non-topological information
requiring persistence. This includes policies, templates, etc.

• Global Cache — The Global Cache enables the NSD and NRC modules to track resources
being used by the network, including the resources of services that originate from the NFM-P. In
order for the NSD to discover such services, they must have their “NSD-managed” flag enabled
within the NFM-P. Once this is done, the usage of VLAN IDs, L3 VPN Route Distinguishers (RD),
and L3 VPN Route Targets (RT) can be tracked across NFM-P/NSD managed networks. When
the NSD requests one of these resources, the Global Cache verifies their availability before
assignment. Only freed resources are considered available for usage. All services created using
the NSD will be validated for resource usage, and therefore will not infringe upon the resources
of existing services.
