Is-Is protocol model suite: Simulation of implemented features and their configuration

Abstract

In recent times, the Intermediate System to Intermediate System (IS-IS) protocol gains more attention from network administrators and users alike. As many service providers engage in the active usage of this protocol, the IS-IS protocol has unfolded a new stream of research regarding its applicability in different scenarios. In contrast to existing distance vector protocols, the IS-IS In basic terms is a link state protocol (LSP) supporting extremely large networks. It is also known for its robustness and an easily adaptable protocol powering cutting edge technologies like the Multiprotocol Label Switching (MPLS), a system used for traffic engineering. A major reason in considering wide application of the IS-IS protocol is its ability to efficiently move large chunk of data within group of connected computers or within a network(area) and still achieving best route for data delivery. Because of the ability of the Optimized Network Engineering Tool (OPNET) to effectively study the internal operations of a simulated network, we conducted experiments using OPNET to demonstrate various implemented features of IS-IS and to explain their configuration.
