Network virtualization is recognized as an enabling technology for the future Internet. It aims
to overcome the resistance of the current Internet to architectural change. Application of this …

In the upcoming 5G networks and following the emerging software-defined
networking/network function virtualization (SDN/NFV) paradigm, demanded services will be …

In this paper, we investigate the issue of how to map an application request upon a substrate
network in such a way that the selected hosting node and link sets can provide not only …

We describe QoSMap, an overlay construction mechanism which computes high quality
overlay networks for applications having stringent constraints on hop-degrading QoS metrics …

Overlay mapping provides a flexible and effective means of application deployment by
selecting a subset of nodes and links from the substrate-hosting network to meet, or even …

Network virtualization is a growing trend in the implementation of Internet infrastructures.
The Virtual Network Embedding problem is one of the challenges in the virtualization of …

Network services in 5G will be rolled out as pools of virtual network functions (VNFs)
exploiting the advantages of both software-defined networking and network function …

The problem of overlay mapping with enhanced resilience and QoS is NP-hard and
previous heuristics are oblivious to substrate topology information and thus cannot provide …

Message Oriented Middleware (MOM) is widely recognized as a promising solution for the
communications between heterogeneous distributed systems. Because the resilience and …
