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
