Energy-Aware Virtual Network Embedding Approach for Distributed Cloud
Network virtualization has caught the attention of many researchers in recent years. It facilitates the process of creating several virtual networks over a single physical network. Despite this advantage, however, network virtualization suffers from the problem of mapping virtual links and nodes to physical network in most efficient way. This problem is called virtual network embedding (“VNE”)....
متن کاملTowards security-aware virtual network embedding
Network virtualization is one of the fundamental building blocks of cloud computing, where computation, storage and networking resources are shared through virtualization technologies. However, the complexity of virtualization exposes additional security vulnerabilities, which can be taken advantage of by malicious users. While traditional network security technologies can help in virtualized e...
متن کاملMemetic Multi-Objective Particle Swarm Optimization-Based Energy-Aware Virtual Network Embedding
In cloud infrastructure, accommodating multiple virtual networks on a single physical network reduces power consumed by physical resources and minimizes cost of operating cloud data centers. However, mapping multiple virtual network resources to physical network components, called virtual network embedding (VNE), is known to be NP-hard. With considering energy efficiency, the problem becomes mo...
متن کاملTopology-aware Virtual Network Embedding Using Multiple Characteristics
Network virtualization provides a promising tool to allow multiple heterogeneous virtual networks to run on a shared substrate network simultaneously. A long-standing challenge in network virtualization is the Virtual Network Embedding (VNE) problem: how to embed virtual networks onto specific physical nodes and links in the substrate network effectively. Recent research presents several heuris...
متن کاملDistributed Virtual Network Embedding
The Internet in its current form is considered to be inflexible and difficult to change. Though a number of innovations and improvements (like DiffServ/IntServ, IPv6, ...) have been proposed, the actual architecture of the Internet has experienced a very slow adoption of new ideas. Network virtualization has been recognized as a tool to overcome this perceived ossification [1, 2]. Network virtu...
