    We propose an approach for providing Quality-of-Service guarantees in a virtual channel Network-on-Chip. The approach is based on virtual channel reservation - routes with guaranteed lower throughput bound are reserved over the virtual channels. The performance of such an approach is limited by a number of factors: number of virtual channel in the network, number of requested routes, traffic locality etc. We test the performance of the proposed approach for variety of traffic conditions. We investigate the influence of three system parameters - routing algorithm, network topology and communication locality - on the performance limits of the approach. The results are derived by simulations using a streaming traffic model. The results show the approach is feasible for a network of size 10-by-10 with four virtual channels per physical channel. The traffic locality has strong influence on the performance limits of the approach and can also help in reducing the communication energy cost by 50% to 70%. The type of the routing algorithm does not practically influence the performance limits.
