in this paper, we discuss the difficulties Reserved Bandwidth Mechanisms for networks-on-chip by MPLS packet-forwarding technologies. Then, we compare these mechanisms in Network-On-Chip that is based on applying the well-known MPLS technology of large-scale computer networks to the on-chip environment. The NS-2 network simulator is used to evaluate the concept for a typical communications scenario that must support several classes of traffic having a range of QoS requirements.
