Network Functions

• Data Center Appliance Market $4.0 Billion by 2017

• Virtual Appliances will reach 30% of total revenue by 2017

• Virtualized private cloud-based enterprise services will grow from $2.2 billion in 2011 to $8 billion in 2016

Enterprise adoption of private clouds in service provider datacenters will likewise impact the need to change the underlying network to SDN technology. The large NEP systems vendors are already well positioned to develop these SDN-based opportunities and capitalize on the growth in demand for virtualized private cloud-based enterprise services, which IDC forecasts will grow from $2.2 billion in 2011 to $8 billion in 2016.

Oracle Virtual Networking

• Oracle Virtual Networking addresses the various issues with Fixed Network Function Appliances• Taking advantage of Oracle SDN, we can deliver Virtual Network Functions

dynamically and with a higher level of security


Oracle Virtual NetworkingHigh-speed, Converged Network Fabric for the Data Center

1) Converged Infrastructure and I/O Consolidation Solution2) Accelerates Applications and Optimizes Server to Server

Data Traffic3) “On-Demand” Network provisioning enables a true

“Cloud” Infrastructure4) Reduces Infrastructure Complexity by 70%

Use Case: Enterprise Multi Tenant Cloud

• Requirements– Create multiple virtual networks on same physical

network– Complete isolation between the tenants– On Demand High Availability and Disaster Recovery

• Traditional networking Implementation– Each tenant will receive his own VLAN

• Limitations– Requires switch level configuration– Dependency on external physical appliances– VLAN Exhaustion

Challenges with Traditional Networking OVN and NFV Solution• Complete isolation between the different

tenants– Separate NFV instances per tenant – High Availability with backup NFV instances– Custom service deployment vs. one-size-fits-all

hardware solutions!

• Predictable Performance and Bandwidth
