Explore a 21-minute conference talk from NSDI '20 that delves into the experiences of modeling network topologies at multiple levels of abstraction. Learn about MALT (Multi-Abstraction-Layer Topology representation), a comprehensive system designed to support all phases of network management, from design to analysis. Discover how MALT enables interoperability across network management software and ties low-level network elements to high-level design intent through abstraction. Gain insights into the software ecosystem supporting MALT's efficient use and the challenges faced in curating a comprehensive, evolving taxonomy for topology representation. Understand the importance of explicit topology representation in automated network management and how MALT's declarative style simplifies what-if analysis and testbed support. The talk covers various aspects including network lifecycle management, automation, standard representation, entity relationships, and the evolution of the entity relationship model. Read more
