Connectivity Provider.

Today

Smartphone, 4G/LTE data cards, and app stores are driving exponential growth in mobile data traffic leading to congestion on the network, increasing security threats, and extending new revenue sources.

Mobile Operators Paradigm Shift

Experience Provider.

Tomorrow

Rapidly moving to a content/application delivery model over LTE networks. Implementing new application/service delivery models including Voice over LTE, and expanding into new vertical applications (such as Healthcare etc.,.

Paradigm shift in:• Network architecture• Business Models• Service delivery

Application Delivery Network Attributes

L4-L7 Awareness

Identifying New Services

Offer New Application based connectivity

Adaptable & Optimizing Network

Automating Operations

Improving Customer Service

Providing the knowledge to enable the business to operate where services are running

Differentiating with speed to market and driving top line

Creating the best user experience possible to attract and maintain subscribers on a network

that can adapt to the changing landscape

Provide new levels of network visibility to streamline operations

and customer care

Cloudifying operations to streamline operations

New offering for M2M and offerings tailored to specific markets and industries


Key Component of the Application Delivery Network

• Application/Service Directory (DNS) – to efficient manage the services

• Network Signaling Awareness – to manage the network

• Subscriber Awareness – to tailor services on a per user basis

• Application Awareness – at the heart of the ADN

• Centralized Policy Management – to tie all the component together

Challenges

• Complex architecture… hard to scale

• Results in high CapEx and OpEx

• Difficult to add new services (requires changes to multiple elements, VLAN management…)

Application Delivery NetworksSummary• Operators need to shift from providing only connectivity to providing

a compelling user experience

• The network value has shifted from layer 3 (IP) to layers 4-7 – the application layers

• The network needs to be policy aware, service aware, and highly adaptable to the changing market landscape

• The network needs to move from static inflexible elements to software-based and programmable elements to help operators address the market changes today and in the future
