Network virtualization has been considered as an enabling technology for future network, through which multiple heterogeneous virtual networks can run on a shared infrastructure. In order to study and test the network management mechanism of future network, we develop and implement a network operation simulation platform of the network virtualization environment. The platform mainly simulates the...
Survivable virtual network embedding (SVNE) aims at embedding a virtual network (VN) in a way, that after being affected by substrate failures, the VN is still operating. Based on the single node failure assumption, that at any time there can be at most one failed substrate node, the existing studies for the SVNE against substrate node failures back up VNs with a maximum resource sharing. However,...
Network virtualization has been regarded as a core attribute of the Future Internet. In a Network Virtualization Environment (NVE), heterogeneous virtual networks can share the same physical infrastructure regardless of their different topologies, demands, protocols and so on. In this case, the Survivable Virtual Network Embedding (SVNE) problem becomes increasingly critical to overcome the failure...
Network virtualization has garnered great attention as a promising way to reform the current Internet. Multiple virtual networks (VNs) can be embedded onto the same substrate network through network virtualization. Recently the survivability of the VNs in the event of substrate failures has been attracting a broad attention. A good way to provide survivability is to use a hybrid strategy, which proactively...
Recently, network virtualization is an emerging trend to address the ossification of the Internet. The key idea of network virtualization is to run multiple architectures simultaneously on a shared substrate. A major challenge in network virtualization is how to assign substrate resources among multiple Virtual Networks (VN) requests efficiently. VN assignment with reconfiguration should be used to...
