Virtual network embedding arranges virtual network services onto substrate network
components. The performance of embedding algorithms determines the effectiveness and …

Network function virtualization (NFV) is a promising technology to decouple the network
functions from dedicated hardware elements, leading to the significant cost reduction in …

Network virtualization helps overcome shortcomings of the current Internet architecture. The
virtualized network architecture enables coexistence of multiple virtual networks (VNs) on an …

Network slicing allows mobile operators to offer, via proper abstractions, mobile
infrastructure (radio, networking, computing) to vertical sectors traditionally alien to the telco …

Network virtualization (NV) is pushed forward by its proponents as a crucial attribute of next
generation network, aiming at overcoming the gradual ossification of current networks …

This paper tries to solve the location-constrained virtual network embedding (LC-VNE)
problem efficiently. We first investigate the complexity of LC-VNE, and by leveraging the …

NFV is promising to lower the network operator's capital expenditure and operational
expenditure by replacing proprietary hardware-based network equipment with software …

It is known that by leveraging programmable data plane, in-band network telemetry (INT)
can be realized to provide a powerful and promising method to collect realtime network …

This work addresses the relatively long setup latency and complicated network control and
management caused by on-demand virtual network function service chain (vNF-SC) …

This paper proposes a self-taught anomaly detection framework for optical networks. The
proposed framework makes use of a hybrid unsupervised and supervised machine learning …
