The unprecedented growth of the global Internet traffic, coupled with the large spatio-
temporal fluctuations that create, to some extent, predictable tidal traffic conditions, are …

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

Network function virtualization (NFV) is a promising technology to decouple the network
functions from dedicated hardware elements, leading to the significant cost reduction in …

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 …

Fog computing reduces the latency induced by distant clouds by enabling the deployment of
some application components at the edge of the network, on fog nodes, while keeping …

This paper studies the problem of service chain (SC) deployment. Specifically, we try to
place virtual network functions (vNFs) on network nodes and connect the vNFs in sequence …

It is known that by leveraging programmable data plane, in-band network telemetry (INT)
can be realized to provide a powerful and promising method to collect realtime network …

This work addresses the relatively long setup latency and complicated network control and
management caused by on-demand virtual network function service chain (vNF-SC) …

Network function virtualization (NFV) in elastic optical datacenter interconnections (EO-
DCIs) enables flexible and timely deployment of network services. However, as the service …

Value-added services (eg, overlaid video advertisements) have become an integral part of
today's content delivery networks (CDNs). To offer cost-efficient, scalable, and more agile …
