Rethinking virtual network embedding
ACM SIGCOMM Computer Communication Review, 2008Network virtualization is a powerful way to run multiple architectures or experiments simultaneously on a shared infrastructure. However, making efficient use of the underlying resources requires effective techniques for virtual network embedding--mapping each virtual network to specific nodes and links in the substrate network.

SVNE: Survivable Virtual Network Embedding Algorithms for Network Virtualization
IEEE Transactions on Network and Service Management, 2013Network virtualization can offer more flexibility and better manageability for the future Internet by allowing multiple heterogeneous virtual networks (VN) to coexist on a shared infrastructure provider (InP) network. A major challenge in this respect is the VN embedding problem that deals with the efficient mapping of virtual resources on InP network ...

Resilient virtual network embedding
2013 IEEE International Conference on Communications (ICC), 2013Our focus, in this paper is on the embedding problem which consists on the mapping of Virtual Network (VN) resources onto physical infrastructure network. In relevant literature, number of works have been proposed to solve this challenging problem. However, few proposals have been dedicated to provide backup mapping mechanism for failing physical links.

Embedding parallelizable virtual networks
Computer Communications, 2017Network virtualization has been the focus of intense research interest for the last decade as it provides a promising approach to overcome the ossification of the Internet. An important problem in network virtualization is how to efficiently embed virtual networks with resource constraints into a substrate network (aka. virtual network embedding). Many

Virtual Network Embedding for Evolving Networks
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010Network virtualization has been proposed as a powerful vehicle for running multiple customized networks on a shared infrastructure. Virtual network embedding is a critical step for network virtualization that deals with efficient mapping of virtual nodes and virtual links onto the substrate network resources.

COVE: Co-operative Virtual Network Embedding for Network Virtualization
Journal of Network and Systems Management, 2017Network virtualization provides a promising solution for next-generation network management by allowing multiple isolated and heterogeneous virtual networks to coexist and run on a shared substrate network. A long-standing challenge in network virtualization is how to effectively and efficiently map these virtual nodes and links of heterogeneous ...

Connectivity-aware virtual network embedding
2016 IFIP Networking Conference (IFIP Networking) and Workshops, 2016The problem of ensuring virtual network (VN) connectivity in presence of multiple link failures in the substrate network (SN) is not well investigated in Network Virtualization (NV) literature. We name this problem as Connectivity-aware Virtual Network Embedding (CoViNE).

Policy-compliant virtual network embedding
2014 IFIP Networking Conference, 2014Virtual network embedding algorithms that opti- mize the mapping of virtual network (VN) topologies onto a substrate network usually do not comply with the policies of substrate providers which may prefer to identify and embed the most profitable subset of a VN request.
