Advances in Software Defined Networking and SD-WAN – Cisco Blogs

Network agility is defined as the speed at which a network can adapt to change while maintaining its operational properties. Software Defined Networking (SDN) is the foundation for network agility and includes LAN, WAN, and Cloud. The following blog posts and paper discuss Cisco’s implementation of SDN as SD-Access, SD-WAN, and Cloud Native SD-WAN, as well as their advantages and the standardization efforts required for interoperability.

Bringing Cloud Native SD-WAN to the SD-WAN Standardization Process at MEF

The Cloud Native SD-WAN open-source initiative is playing an important role in the SD-WAN standardization happening at MEF, a global leading industry forum. Cloud Native SD-WAN in combination with the MEF 3.0 SD-WAN service standard provides a unique opportunity to streamline the consumption of SD-WAN services by Kubernetes applications. Cisco authors Alberto Rodriguez-Natal, Fabio Maino, and Charles Eckel get into details in this blog post, part of the MEF 3.0 Edge VIEW series.

SD-WAN and Kubernetes: Better Together

Learn about the Cloud Native SD-WAN project (aka CN-WAN), an open source initiative announced at KubeCon Europe 2020. With so many enterprises deploying SD-WAN and Kubernetes right now, a tighter integration between these two solutions can really optimize the end-to-end application experience. Check out the blog post at vmblog.com where Cisco employee Alberto Rodriguez-Natal describes how CN-WAN makes this possible.

Designing, Deploying, Operating and Evaluating Cisco Software-Defined Access

Enterprise networks, over the years, have become more and more complex trying to keep up with new requirements that challenge traditional solutions. Here are the results for two real-life experiences with deploying Cisco Software-Defined Access: an enterprise campus, and a large warehouse with mobile robots. This interesting paper published at CoNext 2020, the ACM International Conference on emerging Networking Experiments and Technologies, shows that Cisco SD-Access, when compared with traditional enterprise networks, can significantly reduce overall data plane forwarding state and reduce by an order of magnitude the handover delays in scenarios of massive mobility with respect to other approaches.

Read the paper on SD-Access: Practical Experiences, in which Cisco employees Jordi Paillisse, Marc Portoles, Alberto Rodriguez-Natal, Victor Moreno, Fabio Maino and Sanjay Hooda guide you through the use cases and discuss lessons learned while designing, deploying and operating Cisco SD-Access.
