What is the problem with current Enterprise WAN solutions?• Customer applications are moving toward

SaaS and PaaS models. As such, hair pinning traffic from branch office to customer data center first, then to cloud causes performance issues.

• Internet has become almost as reliable as dedicated IP (MPLS) networks at a fraction of the cost.

• Customers have less IT staff that understand the complexities of the myriad of branch CPE that is required to secure and optimize the WAN. Any single branch office could have a router, firewall, security appliance, wan acceleration device, caching device, etc. It is too much cost for the customer to manage and maintain all that hardware.

Cisco iWAN solution aims to put an intelligent device on customer premise to leverage multiple connectivity to cloud and internal resources with performance based routing guiding the traffic to the correct path.

What are the demands facing IT departments?

Public Cloud

Private Data Center

Private Cloud

Thanks to Cloud, Customers have gotten used to optimizing cost by hosting applications in different Infrastructure domains

based on Mission Criticality of the Application.

e.g. AmazonHost the test/dev apps, the web2.0

apps. Low security

e.g. Rackspace

Host critical apps that have

performance requirements for

storage and speed but can be virtual.

e.g. Customer Premise

Host apps that must be kept in house

due to regulatory or compliance, or

cannot be virtualized.

User spins up resources on-demand intelligently choosing the best platform for the app.

This is the premise of

Hybrid Cloud

Public IP 3rd party Cloud connectivity

Private IP

In a similar fashion, Hybrid WAN needs to offer customers a way to optimize cost by intelligently choosing options of

infrastructure types that are matched with mission criticality.

e.g. IPSecFor small

office/home office or apps that do not require more than

best effort performance

e.g. MPLScritical apps that

have performance requirements for

latency and delivery

e.g. Cloud X fusion

Fastest path from WAN to SaaS and

PaaS providers

User spins up NETWORK on-demand intelligently choosing the best NETWORK for the app.

This is the premise of Hybrid WAN

DR

e.g. Active Active

critical apps that have performance requirements for availability and

disaster recovery

Solutions: SD WAN is Step 1, NFV is Step 2

Public IP 3rd party Cloud connectivity

Private IP

While Hybrid WAN offers multiple infrastructure options for customers under a single operational model, the ability for the

customer to spin up these resources via a software layer is what makes the Software Defined WAN the next level.

e.g. IPSecFor small

office/home office or apps that do not require more than

best effort performance

e.g. MPLScritical apps that

have performance requirements for

latency and delivery

e.g. Cloud X fusion

Fastest path from WAN to SaaS and

PaaS providers

Once there is a single customer portal for control of network services, then we can easily supply the customer with branch office CPE replacement via NFV capabilities.
