Abstract
The architecture of Multiprotocol Label Switching (MPLS) is successfully deployed in networks of many service providers, including telecommunication companies. The technology promises to provide Quality of Service (QoS) in IP networks and introduce a mechanism for effective traffic control. Because of the great complexity of analytical models, simulation is an effective technique for evaluating traffic engineering methods and new algorithms. In this paper, we present a model and the application msim, a C++-based simulator of MPLS networks. Its open structure allows for easy extension of new models and algorithms. Measurements results generated by the tool for networks of up to 100 nodes in size were presented at several international traffic engineering conferences. We present the logical structure of the program as well as example measurements scenarios and results, for packet and connection level simulations. We also describe shortly the Vims, a graphical extension to the msim simulator.
