Openflow

Openflow is an application that leverages the OpenFlow protocol, a key component of Software-Defined Networking (SDN). OpenFlow allows network operators to manage their networks by separating the control plane from the data plane, enabling more flexible and programmable network management. This approach enables networks to be controlled similarly to server clusters, making it easier to manage, test, and extend network functionalities using modern systems management tools.

The OpenFlow protocol supports the use of OpenFlow controllers like Faucet, which is a compact, open-source controller designed to work with OpenFlow 1.3 hardware. Faucet is known for its simplicity and scalability, allowing it to manage complex networks efficiently by offloading forwarding tasks to OpenFlow switches. It also supports features like high availability and multi-table packet processing pipelines, which enhance network performance and scalability.

Openflow applications typically provide features such as network monitoring, traffic management, and security through Access Control Lists (ACLs). These features allow users to define rules for packet forwarding, filtering, and modification, which can be applied to specific ports or VLANs. By utilizing OpenFlow, users can create more dynamic and responsive networks that can adapt to changing conditions and requirements. Overall, Openflow technology offers a robust framework for managing and optimizing network infrastructure in a flexible and scalable manner.
