Virtual Network Embedding Approximations: Leveraging Randomized Rounding [PDF]

open access: yes2018 IFIP Networking Conference (IFIP Networking) and Workshops, 2018
The Virtual Network Embedding Problem (VNEP) captures the essence of many resource allocation problems of today’s infrastructure providers, which offer their physical computation and networking resources to customers.

Network Virtualization and Programmability [PDF]

open access: yes, 2010
We present network virtualization (building virtual or logical networks over a physical infrastructure) and network programmability (allowing the network operator to at least control the network but more fundamentally to define its behavior) concepts.

Robust network function virtualization [PDF]

open access: yesNetworks, 2020
AbstractNetwork function virtualization (NFV) enables on‐demand network function (NF) deployment providing agile and dynamic network services. Through an evaluation metric that quantifies the minimal reliability among all NFs for all demands, service providers and operators may better facilitate flexible NF service recovery and migration, thus offering

On distributed virtual network embedding with guarantees [PDF]

open access: yes, 2014
To provide wide-area network services, resources from different infrastructure providers are needed. Leveraging the consensus-based resource allocation literature, we propose a general distributed auction mechanism for the (NP-hard) virtual network (VNET)
