Dynamic and flexible optical networking enabled by NFV SDN are the key technology enablers for supporting dynamicity bandwidth requirements of emerging 5G network services. To achieve objective 5G, Network Services (NSes) must be often deployed transparently over multiple administrative technological domains. Such case presents security risks since a typical NS may comprise chain functions, each executed in different remote locations, tampering within infrastructure compromise their...
Extensive research is underway to meet the hyper-connectivity demands of 6G networks, driven by applications like XR/VR and holographic communications, which generate substantial data requiring network-based processing, transmission, analysis. However, adhering diverse privacy security policies in anticipated multi-domain, multi-tenancy scenarios presents a significant challenge. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Federated...
Network Function Virtualization (NFV) enables the implementation of Service Chains (SFCs), where a set ordered Virtual Functions (VNFs) support diverse network services over resources. However, deploying SFCs across multiple domains faces challenges due to resource limitations and confidentiality domain-specific data. Achieving lowlatency SFC placement, followed by deployed service performance guarantee, is under research. Maintaining low endto-end (E2E) latency delivery, while preserving...
Currently, telecommunication research communities are striving towards the adoption of Zero-touch network and Service Management (ZSM) in Network Function Virtualisation (NFV) orchestration. Contemporary efforts on adopting Machine Learning (ML) Artificial Intelligence (AI) have caused an upsurge ZSM application VNF space. While ML AI complement goals for building intelligent NFV orchestration, a deep knowledge about resource consumption by Services (NSs) its constituent Virtual Functions...
Leveraging the potential of Virtualised Network Functions (VNFs) requires a clear understanding link between resource consumption and performance.

Taking different approach, iOn-Profiler poses novel profiler optimising multi-resource type allocation performance objectives using adapted...
The increasing concerns of knowledge transfer and data privacy challenge the traditional gather-and-analyse paradigm in networks. Specifically, intelligent orchestration Virtual Network Functions (VNFs) requires understanding profiling resource consumption. However, all kinds VNFs is time-consuming. It important to consider transferring well-profiled VNF other lack-profiled types while keeping private. To this end, paper proposes a Federated Transfer Component Analysis (FTCA) method between...
