This paper discusses the design problems of virtual-path (VP) networks and the underlying transmission-path (TP) networks using a self-sizing capability of VP network layer. "Self-sizing" implies that VP bandwidths can be automatically adjusted based on traffic conditions observed in real time. The notion of "bandwidth demand" is introduced to overcome some of the problems of VP bandwidth sizing, e. g., complex traffic statistics and diverse quality of service requirements. Using the bandwidth demand concept, a VP-bandwidth-sizing procedure is proposed in which real-time estimation of VP bandwidth demand and successive VP bandwidth allocation are jointly utilized. Next, TP bandwidth demand, including extra capacity to cover single-link failures, is defined and used to measure the congestion level of the TP. Finally, a TP provisioning method is proposed that uses TP "lifetime" analysis.
