An Enterprise network is a combination of different types of networks consisting of Ethernet, wireless, Voice over IP and several others. It is a fact that as the size of the organization increases so also the networks, as well as the number of computational requirements on its network, should be increased and optimized. Hence, effective management of these resources in a high-traffic environment in a reliable manner is challenging and requires a stable network flow. Fault-tolerance in an enterprise network for large organizations poses a big challenge for the network designers. In this Research work, two techniques are proposed to provide a fault tolerance system. The use of redundancy in the network infrastructure and the use of adaptive technology are proposed. Conducted simulations and research revealed that network robusity will be improved by employing these techniques. The redundancy technique is the provision of hot and cold functional capabilities that would allow system continuity and functionality in the case of component failure or capacity limitation. Redundant components that automatically take over operation when an equivalent functional component fails or seized. Riverbed Opnet Modeler Simulation tool is used to simulate the performance of the technique. As part of an increasing system, robusity and continuity in failure situations and faults, adaptive components such as H.264 codec and beyond (H.265) be employed for better performance
