  1. Software–Defined Networking Meron Aymiro

  2. What is Software-Defined Networking? • Software-Defined Networking (SDN) has the potential of to transcend the limitations of the current networking infrastructures. • “The basic premise behind SDN is that by separating control of network functions from hardware devices, administrators acquire more power to route and direct traffic in response to changing requirements.” 1 • Control Plane • Data plane

  3. Issues with Traditional IP Networking They are complex and hard to manage. • The control plane and the data plane are joined together in a network device. • During configuration - Each individual network device must be configured separately using Vendor-specific commands • Network environments have to endure the dynamics of faults and adapt to load changes • Slow progressions of improvement.

  4. Why use SDN? The separation of the control plane from data plane will give ways • Directly programmable • Simplification of network devices • Inexpensive • Flexibility • Scalability • Optimization of resources

  5. OpenFlow • OpenFlow is the first standard communications interface defined between the control and forwarding layers of an SDN architecture • This communication protocol that gives access to the forwarding plane of a network switch or router over the network. • OpenFlow enabled network controllers to determine the path of network packets across a network of switches. • Currently most vendor of commercial switches now include support of the OpenFlow application programming interface (API) • https://www.opennetworking.org/sdn-resources/openflow

  6. Layers of SDN

  7. SDN is the future of networking. • SDN was projected to grow into a $3.7 billion industry in 2016 • SDN is already servicing big companies like Google, Facebook, Yahoo, Verizon • Since vedor- locking will not be an issue with SDN, it will invite more research and innovation
