Programmability and virtualization have both become the trends of next generation networks. ForCES (Forwarding and Control Element Seperation) is a new programmable framework for network element. We introduce virtualization into ForCES, propose a method of ForCES virtualization, design its framework, implement a prototype system named vForTER, and test its performance in different scenarios. Te...

Network functions virtualization (NFV) is an appealing vision that promises to dramatically reduce capital and operating expenses for cellular providers. However, existing efforts in this space leave open broad issues about how NFV deployments should be instantiated or how they should be provisioned. In this paper, we present an initial attempt at a framework that will help network operators sy...

In this paper, the potential security issues brought by the virtualization of a Software Defined Networks (SDN) would be analyzed. The virtualization of SDN is achieved by FlowVisor (FV). With FV, a physical network is divided into multiple isolated logical networks while the underlying resources are still shared by different slices (isolated logical networks). However, along with the benefits ...

Network virtualization promises to fulfill the demand for an agile Internet that is friendly to technological innovation. In the past, tremendous effort s have been dedicated to studying the fundamental problem in network virtualization, namely Virtual Network Embedding (VNE). However, until recently, very limited work has addressed the security issues and implications of VNE or network virtual...

Network Functions Virtualization (NFV) allows flexibility, scalability, agility, and easy manageability of networks by leveraging the features virtualization cloud computing technologies. However, softwarization network functions imposes many challenges. Reliability latency are major challenges in NFV-enabled 5G that can lead to customer dissatisfaction revenue loss. In general, redundancy is u...

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...

Parts I, II and III of this four paper series detailed how software-defined networking (SDN) and network functions virtualization (NFV) are enabling a more flexible networking architecture compared to traditional approaches that use fixed-function network elements. They also described high-level hardware and software requirements for the SDN architecture, relevant Intel reference designs, and o...

Many factors influence education nowadays. Educational institutions are faced with budget cuttings, outdated IT, data security management and the willingness to integrate remote learning at home. Virtualization technologies provide innovative solutions to the problems. The paper presents an original educational infrastructure using virtualization technologies implemented in a training process a...

Mobile virtual network operators (MVNOs) are mobile operators without their own infrastructure or government issued spectrum licenses. They purchase spectrum resources from primary mobile network operators (MNOs) to provide communication services under their own brands. MVNOs are expected to play an important role in mobile network markets, as this will increase the competition in retail market...

Network services which handle large-scale traffic require stability and security for the network. Traffic management for efficient traffic processing is also becoming an important issue. NFV (Network Function Virtualization) architecture has been developed to provide a flexible and effective framework to handle this issue and SFC (Service Function Chaining) technique which can configure a singl...
