Abstract: In network virtualization [Nak 10a], it is important to avoid resource interference, e.g., concerning communication bandwidth and delay, so that a single slice (virtual network) may not disrupt the whole infrastructure. To avoid this type of interference, a method for network-resource isolation (NRI) must be developed. Two types of traffic-control mechanisms, i.e., traffic shaping and traffic policing, can be used for NRI. To more effectively implement NRI using these mechanisms, two methods are proposed in this study: the “per-slice shaping” using weighted fair queuing (WFQ) and the “per-link policing” (per-virtual-link policing).
