Product Overview

Profitably delivering advanced

broadband services to mobile

and residential customers

requires tight control over network

resources, even as services grow

in complexity. In order to make

sound network investments,

maintain regulatory compliance,

and streamline business

operations, service providers

need reliable information about

how the network is utilized and

what applications are being. To

meet this need, Junos Application

Aware extends the ability to

identify applications and take

specific actions on them with

award-winning Juniper Networks

MX Series 3D Universal Edge

Routers integration.

Product Description

As new technologies and new applications are developed, service providers are challenged

to maintain network control and avoid threats and vulnerabilities. Gaining detailed insight

into the applications in use on the network is critical for ensuring quality of service (QoS),

security, and planning processes that drive network upgrades and investments; however,

it can be very difficult to efficiently collect that information. Traditional routing elements

examine Layer 3 IP address information, and largely ignore Layer 4 through Layer 7 (L4-L7)

information that can identify an application based on a variety of criteria.

Juniper Networks helps service providers overcome these challenges by offering Junos®

Application Aware as a fully integrated optional feature on Juniper Networks® MX Series

3D Universal Edge Routers. Junos Application Aware is based on deep packet inspection

(DPI) functions that provide the stateful detection, identification, and analysis of

application-layer traffic (L4-L7) on a per subscriber, per session basis.

Junos Application Aware uses stateful monitoring to provide comprehensive details

of application-layer traffic patterns and statistics that service providers can use to

support revenue-generating mobile and residential broadband services. From a services

perspective, Junos Application Aware in combination with Junos Subscriber Aware and

Junos Policy Control can identify and enforce premium class services, ensure adherence

to service-level agreements, maintain subscriber fairness, and align network resources to

application requirements. Product managers can also use this information to design new

revenue-generating differentiated service offerings.

Architecture and Key Components

Junos Policy Control

When combined with Junos Application Aware and Junos Subscriber Aware, Junos Policy

Control provides dynamic policy and online charging capabilities. Junos Policy Control

enables a Gx Diameter interface towards the Policy Charging and Rules Function (PCRF)

following the Traffic Detection Function (TDF) model in Third-Generation Partnership

Project (3GPP) LTE networks.

Junos Application Aware

Junos Subscriber Aware identifies the subscriber’s association with a flow and classifies

traffic based on subscriber privilege, permitting differentiated services based on

subscriber policy:

• Dynamically redirects new flows to subscriber identification engine and checks

subscriber identity for a policy match

• Configures forwarding plane to forward, rate limit, mark, or drop packets associated

with flow based on policy

• Can be used with Junos Application Aware to correlate application usage with

subscriber identity
