5G and beyond need to meet stringent requirements of latency, reliability, and support for
heterogeneous devices. However, the existing wireless network architecture is limited to …

We propose an online heuristic algorithm for the problem of network slice placement
optimization. The solution is adapted to support placement on large scale networks and …

With the development of heterogeneous network structure, dynamic user requests as well as
complex service types and applications scenarios, current networks may not accommodate …

Network virtualization is envisioned to support flexible, cost effective and on-demand
deployment of multiple Virtual Networks (VNs) on a shared underlying infrastructure. A key …

Network Slicing has its roots in Network Function Virtualization (NFV) allowing high flexibility
in the delivery of end-to-end network services. To achieve Network Slicing promises on …

The rapid development of technologies such as photo-intensive social networks, on-demand
video streaming, online gaming, and the Internet of Things (IoT) is causing a tremendous …

Multi-domain federations support shared network services. Many orchestrators manage the
service's lifecycle. For the shared VNF Forwarding Graph (VNF-FG) reconfiguration …

Age of Information (AoI) is a newly emergent performance metric to quantify the freshness of
data from destinations' perspectives. In this paper, we investigate and analyze AoI in the …

Network function virtualization (NFV) technology is the key technology to solve the flexibility
problem of 5G network. Multiple service function chains (SFCs) that coexist on physical …

Network function virtualization (NFV) is an emerging paradigm that has revolutionized the
deployment and provisioning of telecommunication network services (NS). In NFV, a …
