Abstract
We present two preliminary formalizations of router networks, both
expressed in the logic of the ACL2 theorem prover. One formalization
focuses on connectivity requirements by formalizing validity,
visibility, and a trivial example routing policy, and demonstrates the
ability to execute specifications. The other formalization focuses on
network security properties, specifically information-flow and
non-interference, and includes theorems demonstrating these properties
for a simple formalization of a router network.
