Area of Science:

  • Computer Science
  • Network Engineering
  • Network Verification

Background:

  • Manual configuration errors are the primary cause of network outages.
  • Network configuration verification is crucial for fault tolerance and reliability.
  • Existing routing table calculation tools are user-unfriendly, lack expressiveness, and are slow.

Purpose of the Study:

  • To present FastCAT, a novel framework for computing routing tables that addresses the limitations of existing tools.
  • To enable efficient and accurate network configuration verification through multi-protocol routing table computation.
  • To improve the speed and accuracy of generating routing tables for network simulation.

Main Methods:

  • FastCAT simulates the interaction of multiple routing protocols (OSPF, IS-IS, RIPv2, BGP).
  • It focuses on the stable states of OSPF and IS-IS, disregarding transient convergence states.
  • For RIPv2 and BGP, it computes routing tables based on the previous state, retaining only the latest information.

Main Results:

  • FastCAT significantly accelerates routing table generation compared to state-of-the-art tools.
  • The framework demonstrates higher accuracy in computing routing tables.
  • Experimental evaluations were conducted on networks with approximately 200 routers.

Conclusions:

  • FastCAT offers a user-friendly, expressive, and fast solution for network configuration verification.
  • The framework enhances fault tolerance by enabling accurate routing table generation.
  • FastCAT represents a significant advancement in network simulation and verification tools.
