This paper describes flexible resource allocation and provision methods for bandwidth on demand and networks on demand in the new Japanese academic backbone network, called SINET3. SINET3 has provided a wide variety of network services such as IPv4/IPv6 dual stack, L3VPN, L2VPN/VPLS, and L1VPN services for the research and education community and started layer-1 bandwidth-on-demand services in February 2008. In SINET3 each service network is implemented as a logical service network on a single network platform by effectively combining latest technologies including logical router capabilities of IP/MPLS routers and flexible resource allocation capabilities of layer-1 switches. SINET3 can also easily create logically separated experimental network environments for new research projects. Evaluation results on some capabilities in experimental environments and demonstration results on bandwidth-on-demand capabilities in the real network are also shown in this paper.
