TARVOS - an Event-Based Simulator for Performance Analysis, Supporting MPLS, RSVP-TE, and Fast Recovery

This paper presents a new discrete event-based network simulator named TARVOS - Computer Networks Simulator, being designed as part of the first Author's Masters research and will provide support to simulating MPLS architecture, several RSVP-TE protocol functionalities and fast recovery in case of link failure. The tool is used in a case study, where the impact of a link failure on a VoIP application, within an MPLS domain network, is analyzed. The paper displays a preliminary research of six already available simulators and reasons why they were not adopted as tools for the Masters research. Then, it follows to describe the basics of TARVOS implementation and exhibits the case study simulated by this new tool.
