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

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 non-scalable 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

NCS CE Solution: Initial Engagement/Assessment
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
NCS CE Solution: Planning/Design Follow on Service Provider engagements focus on
gathering requirements for managing specific services (e.g., Carrier Ethernet service offerings) and specific devices within the Service Provider’s network as part of the service delivery Service Management requirements definition
• Review existing library of NCS Service Models Device Management requirements definition
• Obtain list of vendors and versions Interface Management requirements definition
• Interfacing to other OSS/BSS/NMS/EMS applications• Interfacing to other back office applications
24
NCS CE Solution: Implementation/Test These Service Provider engagements focus on
implementing and testing the NCS Carrier Ethernet solution Service package development and testing (YANG, Java) Device package validation Interface definitions (e.g., REST payloads)
25
NCS CE Solution: Training These Service Provider engagements focus on
training the Service Provider on the NCS Carrier Ethernet solution Different levels of training may be required depending on
the user type• On-boarding training of the team for separation of the roles
26
NCS CE Solution: Support & Maintenance These Service Provider engagements focus on on-
going support and maintenance of NCS once the solution has been deployed in the Service Provider’s environment Maintenance upgrades are provided by Tail-f Core NCS support may be provided by DataVision when:
• Tail-f provides Maintenance Upgrades• Service Provider adds, modifies, updates network devices• Service Provider adds, modifies, updates services
