Video description

9+ Hours of Video Instruction

Large Scale Network Design LiveLessons takes you through the concepts behind stable, scalable, elegant network design, including modularity, resilience, layering, and security principles. This livelesson will focus on traditional distributed link state, distance vector, and path vector routing protocols, as well as the basic principles of centralized control planes (such as OpenFlow). A special point will be made of sorting out the relationship between policy and reachability, and where they can best be managed in a large scale network.

This video begins with an examination of basic network design principles, including an examination of modularization, hierarchy, summarization, aggregation, and resilience. More advanced foundational topics are then considered, such as an overview of network complexity, network models, and policy from within the context of the control plane. After this, the series will work through design using each of the distributed control planes, including OSPF, IS-IS, EIGRP, and BGP, on several network topologies to provide practical knowledge of actual deployment in real networks. The following section of this livelesson will consider the tradeoffs around programmable networks, including convergence, stability, and other factors. Finally, advanced topics, such as fast convergence, will be considered in detail, from principle to application in each protocol.
