Network Digital Twin for IGP Weight Optimization Demo

Current research on Network Digital Twins (NDT) focuses on building models that predict the behavior of the network on simulations rather than building a complete NDT that automatically monitors a physical network and optimizes it according to its current state and traffic flows. In this proposal, we demo a NDT for Interior Gateway Protocol (IGP) weight optimization on a physical network of 7 Cisco routers and an IXIA generator connected via Ethernet links. We will show how a link failure in this network results in a large packet loss, and how our NDT automatically optimizes the IGP weights of the network to reduce packet loss. Our demo presents a practical implementation of a NDT, where the audience can see a self-adapting network without human interference.
