Nowadays, telecom providers may benefit from the flexibility offered by Network Function Virtualization (NFV) paradigm that allows to decouple the service logic from the underlying …
The failure of a single network element composing a Service Function Chain (SFC) unavoidably leads to some degradation in terms of availability (ability of guaranteeing …
IP Multimedia Subsystem (IMS) represents a crucial element for the convergence of telecommunication systems heading towards 5G solutions. Actually, IMS offers a …
The Network Function Virtualization (NFV) paradigm is giving impetus to novel telecommunication infrastructures that readily benefit from virtualized environments. One of …
Service provisioning mechanisms implemented across 5G infrastructures take broadly into use the network service chain concept. Typically, it is coupled with Network Function …
Today, modern telco infrastructures are espousing softwarized paradigms (eg virtualization, containerization), which are necessary to implement the network slicing, and, consequently …
We advance a performability assessment of a multi-tenant containerized IP Multimedia Subsystem (cIMS), ie: one and the same infrastructure is shared among different providers …
The reputation of network providers strongly depends on their ability to guarantee high performance levels of virtualized infrastructures, and to maintain strict Quality-of-Service …
In modern telecommunication networks, services are provided through Service Function Chains (SFC), where network resources are implemented by leveraging virtualization and …
