This article proposes a primary and backup resource allocation model that provides a
probabilistic protection guarantee for virtual machines against multiple failures of physical …

Network function virtualization (NFV) is a promising technology that decouples network
functions from hardware. Connecting virtual network functions (VNFs) in series to form a …

A suitable virtual network function (VNF) placement considering a node availability schedule
extends service continuous serviceable time by suppressing service interruptions caused by …

This paper proposes a backup computing and transmission resource allocation model for
virtual networks with providing a probabilistic protection against multiple facility node …

Many internet applications in the emerging 5G/6G networks require ultra-reliable and low-
latency communications (URLLC) services. To deliver URLLC services flexibly and …

In network function virtualization (NFV), the client's service requests will go through multiple
service functions (SFs). The instances of the required SFs will be hosted on the …

Network function virtualization provides an efficient and flexible way to implement network
functions deployed in middleboxes as software running on commodity servers. However, it …

Network virtualization enables cloud service providers sharing various substrate resources
and serving end users with heterogeneous virtual network (VN) applications. As more and …

This paper proposes a multiple backup resource allocation model with a workload-
dependent failure probability to minimize the maximum expected unavailable time (MEUT) …

This paper proposes a robust optimization model for probabilistic protection with multiple
types of resources to minimize the required backup capacity for each type of resource …
