The dependence of traditional network functions (NFs) on special hardware results in high
capital expenditures (CAPEX) and operating expenditures (OPEX). Network Function …

Estimation of end-to-end network traffic plays an important role in traffic engineering and
network planning. The direct measurement of a network's traffic matrix consumes large …

Network Function Virtualization (NFV) and service orchestration simplify the deployment and
management of network and telecommunication services. The deployment of these services …

Abstract Software Defined Networking (SDN) and Network Function Virtualization (NFV) are
the latest promising technologies introduced with the goal of making networks more flexible …

Generally, a service request must specify its required virtual network functions (VNFs) and
their specific order, which is known as the service function chain (SFC). When mapping …

Service function chains (SFCs) are an ordered set of virtual network functions (VNFs) which
can realize a specific network service. Enabled by virtualization technologies, these VNFs …

As a new way to design, deploy, and manage network services, network functions
virtualization (NFV) decouples the network functions, from one or more physical network …

Due to that Service Function Chain (SFC) permits the forwarding of flows along a
predetermined sequence chain of Virtual Network Functions (VNFs), it has become a …

Private and public networks sharing resources for Internet of Things (IoT) network through
network function virtualization (NFV) and software-defined networking (SDN) forms a …

Space-air-ground integrated networks (SAGINs) are envisioned to provide seamless
coverage and enhanced flexibility compared with traditional terrestrial mobile networks …
