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 …

In modern telecommunication networks, services are provided through Service Function
Chains (SFC), where network resources are implemented by leveraging virtualization and …

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 …

As a case study of a novel approach to characterize service chains in terms of performance
and availability, we consider a containerized IP Multimedia Subsystem (cIMS) infrastructure …

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 …

The Next Generation 5G Networks can greatly benefit from the synergy between
virtualization paradigms, such as the Network Function Virtualization (NFV), and service …

Nowadays, most telecommunication services adhere to the Service Function Chain (SFC)
paradigm, where network functions are implemented via software. In particular, container …

As of today, telecommunication providers are exploiting the possibilities offered by the cloud
paradigm to efficiently decouple physical network resources, like hardware equipment …

IP Multimedia Subsystem (IMS) represents a crucial element for the convergence of
