Energy-Aware Virtual Network Embedding [PDF]
IEEE/ACM Transactions on Networking, 2014 Virtual network embedding, which means mapping virtual networks requested by users to a shared substrate network maintained by an Internet service provider, is a key function that network virtualization needs to provide. Prior work on virtual network embedding has primarily focused on maximizing the revenue of the Internet service provider and did not ...

Competitive and deterministic embeddings of virtual networks [PDF]
Theoretical Computer Science, 2012 Network virtualization is an important concept to overcome the ossification of today's Internet as it facilitates innovation also in the network core and as it promises a more efficient use of the given resources and infrastructure. Virtual networks (VNets) provide an abstraction of the physical network: multiple VNets may cohabit the same physical ...
