Software defined networking, or SDN, is a technology that allows network administrators to treat the functionality and implementation details of a network as separate and distinct functions. In this video, learn how SDN is changing networking and the security implications of this change.
- [Instructor] Software-defined networking, or SDN,…is a technology that allows network administrators…to treat the functionality and implementation details…of a network as separate and distinct functions.…In a traditional approach to networking,…an organization's network infrastructure…is full of routers and switches that provide…both the physical connections that make up the network…and the logical capability to determine network routes,…port assignments, and other characteristics.…
When a network administrator wants to reconfigure…the network, he or she logs into a router or switch…and uses a series of commands to alter the configuration.…While this may be done manually…or using network management software, changes to the network…require configuration changes to routers and switches.…This approach combines two different functions of a network.…The control plane of a network is responsible…for the routing and switching decisions…that determine how data flows around a network.…
The control plane might reroute packets when a device fails…
