Transcript of Service Delivery Using Allot vTDF by Adi Mendel
Service Delivery using the Allot vTDF in a vEPC
Adi Mendel, Director, Product Management
Now that we have NFV...
2
NFV brought a new concept to the network• No need for propriety HW• The solution can be deployed
anywhere in the network• New Services can be
introduced faster
NFV also introduces savings on OPEX and CAPEX and much more …
Still something is missing to be able to benefit from all of this ...
NFV Challenges
3
Complex Eco-system and Integration
• Network overlay/SDN• Orchestration• OSS\BSS (PCRF\OCS)
Complex services require subscribers awareness
• Each subscriber gets a different service
Value added services are application based
• Need the ability to distinguish between application
Multiple physical locations
• Not all services are deployed in all the data centers
• Services require Service chaining across pops
Growth of services require the solution to have elasticity
• Provide and guarantee QoE and SLA to users
• Resource orchestration• Dynamic load balancing
Our Value Proposition • Allot is a leading global provider of intelligent broadband solutions
• Traffic Detection Function (TDF) solutions provide Granular Visibility

Virtual TDF
5
The first to introduce a virtual Traffic Detection Function
vTDF is capable of leveraging Application Awareness in a virtualized evolved Packet Core Network
Allot’ vTDF is aligned with ETSI NFV
vTDF – Approaching Challenges in the NFV era
6
Provide the required Elasticity of Scale and Agility to provide required resources anywhere in the network to ensure services SLA
Provide Network and Subscriber Analytics to ensure QoE
Integration for SDN solution using OpenFlow
Fully and seamlessly integrated with Operator Orchestration using the vNF Manager
Leveraging TDF capabilities to perform efficient and targeted service chaining per Application, Subscriber, Network and Policy.
vTDF – Unique Advantages
7
Enables fast role out of new and complex services based on Application and\or Subscriber awareness without the need to invest on HW deployments and physical installation
Can help launch services in small scales (marketing purposes) and grow as fast as needed, without the need to pre-install HW for large scale deployments
All of Allot’s technology knowhow and collaboration built into the virtual architecture as well.
The Motivation
Use Case 1: vCPE QoS Configuration based on Application Detection using OpenFlow
8
Ability to offer customers advanced add-on services without adding H/W on customer premises:
• Prioritize traffic/QoS according to:
• User profile
• Application type
• Firewall
• Anti virus/Malware
• URL filtering
Immediate and simple ROI:
• The cost of sending engineer to
customer premises
• The cost of dedicated equipment (stock
levels, spare parts, etc)
• Time to market
The Challenge:
Use Case 1: vCPE QoS Configuration based on Application Detection using OpenFlow
9
• To be able to detect a specific
customer on each CPE
• To detect application and services
and based on dynamic policy
allocation to define QoS for the
specific flow
• Using Allot’s vTDF for L4-7 and
application awareness with flow
detection using DPI
• Each flow can be classified to
provide dedicated QoS
• Using OpenFlow configuration to
the vEPC can be made dynamically
and seamlessly
Allot’s Solution:
POC With Tier 1 Global Operator & MRV for vCPE
10
• The vision of a vCPE for enterprise customers.
• Allot provides L4-7, application awareness and flow detection using DPI
• Allot accepts the desired Policy from the operator frontend
• Both solutions use SDN OpenFlow for control
• MRV enforces QoS policy per application type

Real time classification (and steering) of traffic to the service chain
Service load balancing
Integrates with NFV Orchestrator for new services and scale of instances
VNF manager for all Allot services:
Life cycle management
Application health monitoring
Policy based traffic management and service chaining
Charging for traffic and services
