While the benefits of SDN for the Cloud and data center are well known, the benefits of SDN for the Enterprise are not so well understood. Centralized software control of the Enterprise network allows:
- Rapid reconfiguration in changing circumstances—such as security breaches, fluctuating traffic loads and sudden topology changes.
- A mechanism to dynamically translate organizational policy into network behavior.
- A standardized interface for interaction with network devices, which generates opportunities for creating new applications to control and monitor both your network, and the activity of users and devices.
- Operational cost savings from network management task automation.
Examples of the use of SDN in the Enterprise include:
Analysis of internal network traffic, combined with direct software control of both the wired and wireless access layers of the network, enables rapid threat detection and immediate quarantining of the threat, by disconnecting network access at the threat’s source on a packet by packet basis.
User onboarding and migration
Bring Your Own Device (BYOD) and Choose Your Own programs have resulted in an increasingly mobile workforce, with greater flexibility in choices of user equipment. Centralized management of user and device identity has become a vital challenge in Enterprise networking. Combining user and equipment databases with user access policy rules, and automatically translating that information into operational instructions for the network infrastructure, results in major efficiency improvements, cost savings, and better network security and performance.
