Abstract:The problem of resource provisioning in multi-layer networks is an important issue. We discuss and analyze resource provisioning in terms of the visibility of optical resources for the virtual layer in a network. In this context, we propose the diversification of the optical spectrum in such a way that some resources are hidden for the virtual layer and used when needed. We introduce and investigate automatic hidden lightpaths to improve resource utilization in multi-layer networks. Our solution uses a softwar… Show more
