Abstract:
The high-availability comprises a critical feature of any enterprise local area or data-center network. Because
of the importance of high-availability, network designers and administrators expect support from tools aiding
to deliver the correct configuration. Simulation is widely accepted approach for testing network design and
configuration helping to reveal possible issues in functionality and performance. OMNeT++ simulator
provides INET framework offering models of Internet devices, protocols and mechanisms. This paper
presents an extension of INET framework with two high-availability protocols, namely, HSRP and GLBP.
This extension enables to accurately simulate scenarios with default-gateway redundancy features, which was
not easily possible before. In the paper, we briefly overview the basic concepts of these protocols, describe
the design of simulation models and present verification and validation results.
