The symbolic techniques developed for KATch could be extended to handle more expressive features in network specification languages by incorporating support for dynamic updates to the network topology and state-dependent forwarding behavior. This extension would involve enhancing the symbolic representations to capture the evolving nature of the network, where the topology can change dynamically based on various events or conditions. By introducing symbolic constructs that can represent these dynamic updates, KATch could analyze and verify properties in network models that involve real-time changes in configuration or routing decisions. Additionally, the verification algorithms would need to be adapted to handle the complexities introduced by these dynamic elements, ensuring that the symbolic verification remains efficient and scalable even in the presence of such features.
