Model-based application-aware overlay networks over heterogeneous substrates

The main objective of this proposal is to introduce a next-generation overlay network that lies between the applications and the underlying heterogenous substrate networks. This overlay understands the performance requirements specific to each application, and optimizes them by managing and allocating various types of network resources. The overlay acts as the glue that holds the different substrate networks together and presents a transparent interface to the applications. It also functions as an intelligent optimizing network managing layer which takes specifications from applications and optimally delivers services to satisfy the differing requirements.
