Time-Conscious Network Verifier

Time-Conscious Network Verification

Network Properties

• Network topology
• Switch
  • Forwarding state
  • Queue architecture
  • Queue delay
• Link
  • Failure probability
  • Link delay

Bounded Reachability

Given network properties, compute the probability of a packet from node X reaching node Y in under T time unit

How To Run

• Download and extract UPPAAL (version 4.1.26-1)
• Edit uppaalRootPath in gradle.properties
• (Windows only?) Edit server path in app/src/main/java/tempus/App.java$121 to adjust with your OS
• Run ./gradlew run

Adjust the topology file in config/test.json accordingly (file name is hardcoded for now)

Notes

public enum LKind { name, init, urgent, committed, invariant, exponentialrate, comments };

public enum EKind { select, guard, synchronisation, assignment, comments, probability };
