Latest Patents

One of Reaz Ahmed's latest patents is titled "Multi-layer virtual network embedding." This invention provides effective mechanisms for provisioning virtual networks on communication networks. It focuses on embedding a virtual network into a multi-layered substrate network that utilizes different communication technologies at each layer. For instance, it allows for an IP network to be overlaid on an optical network, such as an OTN network. The invention jointly determines the assignment of virtual nodes and virtual links, leading to more optimal solutions than separate assignments. Additionally, it generates a collapsed graph that includes both the optical and IP networks in a single layer, optimizing the assignment of virtual nodes and links.

Another notable patent is the "System and method for joint embedding and backup provisioning in virtual networks." This invention addresses the Survivable Virtual Network Embedding (SVNE) problem, which involves mapping a virtual network on a substrate network while accounting for potential substrate failures. The solution optimizes spare backup capacity allocation and embedding a virtual network to ensure full bandwidth during a single substrate link failure. This can be formulated as a Quadratic Integer Program or a heuristic.
