In this paper, in order to embed virtual networks by considering network security, we
propose a virtual network embedding based on security level with VNF placement. In this …

Network virtualization has been widely concerned as the new technology to remedy the
current ossification Internet architecture. Previous virtual network (VN) embedding …

Network virtualization promises to play a dominant role in shaping the future Internet by
overcoming the Internet ossification problem. However, due to the injecting of additional …

Network virtualization is a promising technology to enable multiple architectures to run on a
single network. However, virtualization also introduces additional security vulnerabilities that …

Against the new security threats brought by the network virtualization technology, the
concepts of trust relationship and trust degree were introduced into the virtual network …

Virtual network embedding has been gaining interest due to the diverse applications of
virtual networks. Especially building a cooperative testbed for future network design requires …

Software-defined networking (SDN) and network virtualization (NV) are key technologies for
future networks, which allow telecommunication service providers (TSPs) to share network …

Network virtualization is an effective manner to address the ossification issue of Internet
architecture. Virtual network embedding is one of the most critical techniques in network …

In this paper, we propose cost efficient VNF placement with optimization problem for
embedding security-aware virtual networks. In this method, some VNFs are placed in order …

Virtual network embedding (VNE) algorithm is always the key problem in network
