Datavision Carrier Ethernet Solution
the Tail-f Network Control System (NCS)
Tail-f Network Control System
 Highlights the Tail-f Network Control System (NCS)
solution for Service Providers and Access Providers
offering Carrier Ethernet (CE) services
 The purpose of this presentation is as an initial
engagement for Operator discussions around the
Tail-f NCS solution
9
Business Processes: Service Orchestration
 Tail-f’s NCS solution provides a service orchestration
solution for real-time Service Fulfillment across
multi-vendor devices in a Service Provider’s network
 Service Agility is a top priority to drive down the time
to add new features and deploy new services as well
as the cost of Operations
 NCS enables automation of provisioning and
activation of network services, such as replacing
 Manual, labor-intensive and error-prone processes such as
Microsoft Word templates, Excel Spreadsheets and nonscalable CLI scripts executed at the individual device level
10
NCS Business Process Flow: Service Fulfillment
 This example illustrates where NCS provides process automation (yellow
processes) for Service Fulfillment
11
NCS Architecture: A Model Driven Approach
 NCS uses the YANG data modeling language (IETF RFC
6020) for Data Modeling at the Service Manager (Service
Layer) and Device Manager (Device Layer).
 Service-Aware via a Service Manager
 Provides a declarative way to specify how a network
service is applied to the network infrastructure in a
transactional manner
 Transactions are performed as distributed atomic
change sets allowing easy rollback if service
provisioning fails or when service recover is desired
 Network State-Aware via a Device Manager
 The configuration state of the network infrastructure
and NCS database is in constant sync

Interfaces: Northbound, Southbound & Integration
 Tail-f’s NCS Solution provides a wide range of interface
support
 From a southbound perspective into the network, for
device provisioning, NCS supports
 NETCONF, CLI, SNMP, REST, TL1, SOAP (NETCONF + CLI = 80%)
 From a northbound perspective, there are two
northbound interface connection points
 Management Applications
• Supports NETCONF, REST, Java, Python (REST is dominant)
 Network Engineering Access
• Supports Network-wide CLI (Cisco & Juniper) and a Web User
Interface
 From an integration perspective, NCS provides a
Developer and Scripting API interface to allow application
integration
14
Other Benefits of NCS
 NCS does not require installation of an RDBMS
database such as Oracle or MySQL
 NCS does not require specialized appliance hardware
and can be installed on any common Linux server or
MAC laptop/desktop
 NCS provides a migration path the SDN and NFV
when Operators are ready to adopt these
technologies
 NCS is designed for rapid validation and qualification
in a Service Provider’s operations environment

 Initial Service Provider engagements focus on
understanding which business processes are pain
points and where NCS can provide a value add
 Look at Carrier Ethernet service lifecycle from order
acceptance through service activation
 Discuss with CEN Operator, Operations Team, what is
manual today and which processes are error prone, time
consuming and not-scalable
 Demonstrate and discuss with CEN Operator on how NCS
might be useful in their Operations environment
• For example, Proof-of-Concepts for Service Orchestration
23
