The dynamic network state and the mobility of the terminals make the service function chain
(SFC) orchestration mechanisms based on static and deterministic assumptions hard to be …

Abstract Service Function Chaining (SFC) has become an integral part of every emerging
application to satisfy its specific demand. Due to the massive increase in such diverse …

In service function chaining (SFC), an ordered list of service functions (SFs) is specified for
network services, and those SFs should be placed in appropriate service nodes (SNs) to …

In this paper, we consider the problem of optimal dynamic service function (SF) placement
and flow routing in a SF chaining (SFC) enabled network. We formulate a multi-objective …

Emerging 5G technologies can significantly reduce end-to-end service latency for
applications requiring strict quality of service (QoS). With network function virtualization …

The adoption of virtualization technologies in networking is promoting a radical innovation in
the way network services are managed and delivered. Indeed, some network services may …

Traditionally, Network Function Virtualization uses Service Function Chaining (SFC) to place
service functions and chain them with corresponding flows allocation. With the advent of …

Service Function Chains (SFC) orchestration is necessary to optimize the use of computing
resources and improve the performance of the overall virtualized functions in terms of …

Abstract Network Function Virtualization (NFV) opens us great opportunities for network
processing with higher resource efficiency and flexibility. In this respect, there is an …

Modern services consist of modular, interconnected components, eg, microservices forming
a service mesh. To dynamically adjust to ever-changing service demands, service …
