Network function virtualization is a new network architecture, where the dedicated hardware
network functions can be implemented in network function instances running on general …

In this paper, we propose to use static virtual topology for a scalable inter-domain optical
service provisioning, while addressing the resource efficiency issue by using multipath …

Nowadays, most service providers offer their services and support their applications through
federated sets of data centers which need to be interconnected using high-capacity optical …

Abstract Service Function Chaining (SFC) is the problem of deploying various network
service instances over geographically distributed data centers and providing inter …

The combination of software-defined networking (SDN) and optics, ie, a software-defined
optical network (SDON), offers combined benefits that include flexible SDN control and large …

Hierarchical network virtualization is demonstrated on a heterogeneous multi-domain
network testbed, based on SDN/Openflow and two-level Flowvisor. Differentiated services …

It is known that by incorporating network function virtualization (NFV) in inter-datacenter
(inter-DC) networks, service providers can use their network resources more efficiently and …

Vertical industries see 5G networks as an appealing context to enhance their offered
services, capabilities, and products. In the 5G context, such services are formed by a set of …

We propose an efficient procedure, namely disjoint pair procedure based cloud service
embedding procedure that first maps working and backup virtual nodes over physical nodes …

Creating datacenter federations allows balancing workloads accommodating spikes in cloud
demand while reducing the extensive energy consumption of datacenters. This allows …
