  • When Cloud Media Meet Network Function Virtualization: Challenges and Applications

    Recently, network operators around the world have encountered a paradox. On the one hand, they have made enormous investments to handle the tremendous growth of Internet media services triggered by the ubiquitous penetration of high-speed wireless networks and the increasing popularity of mobile devices. On the other hand, these investments have not delivered the expected revenue, leading to declining profitability. In response to this paradox, network function virtualization (NFV) has been proposed as a revolutionary technology to transform network architecture and operations. This emerging technology opens up significant opportunities to reduce the cost of operating media services. In this article, the authors present a survey on this emerging topic. Specifically, they analyze the forces driving the evolution of the network architecture, then describe a novel NFV-enabled media cloud system from two alternative perspectives: an end-to-end view and a layered view. They then illustrate the architectural changes' technical challenges, which range from optimal resource provision and request routing to automated optimization. Finally, they substantiate the NFV-enabled media cloud platform with proof-of- concept case studies. By demonstrating NFV's flexibility and effectiveness, they show that the cost of providing Internet media services by NFV-enabled systems could be substantially reduced in practice.

  • Orchestration of NFV virtual applications based on TOSCA data models

    With the significant increase in Topology and Orchestration Specification for cloud applications (TOSCA) orchestration services on the Network Functions Virtualization (NFV) cloud platforms. We apply the TOSCA metadata model to orchestrate NFV virtual applications and implement the orchestration system based on the Network Function Virtualization (NFV) Management And Orchestration (MANO) architecture to deploy these virtual applications to the virtual network function (VNF) as the part of cloud services. The proposed orchestration system uses TOSCA service templates to orchestrate virtual applications without complex schemes. And in the end we evaluate the performance for orchestrating and automating cloud services in our cloud environment.

  • Self-healing in multi-constrained multi-actor virtualization orchestration

    Multi-constrained multi-provider orchestration is alone challenging, which we complemented with an automated multi-layered failure recovery mechanism. Our proof of concept prototype demonstrates information models (both bottom-up and top-down), orchestration and recovery workflows with delegation, trial and error based backtracking among the chain of federated providers in an Industry 4.0 use-case for critical machine type communication (C-MTC). With a remote factory scenario, we show fault recovery from single to multi provider involvement. We provide insights into the responsibility split for failure handling between service agnostic resource orchestration and service specific lifecycle management components.

  • Application of hybrid computing technologies for high-performance distributed NFV systems

    Currently, the areas of transmission and distributed processing technology commonly used network functions virtualization (NFV). A key feature of these solutions is that they can use in the Cloud. Modern cloud infrastructure often has the GPGPU-coprocessors for acceleration purposes. There are a number of problems in which it is possible to use hybrid computing technology to speed up the NFV: encryption, pattern matching, media content processing (compression, audio/video processing, etc.). In this paper, we propose a new NFV-GPGPU architecture and provide the results of its study in case of AES network virtualized function acceleration.

  • Optimal execution of virtualized network functions in a multi-data-center cloud

    Provisioning services for applications in networks of large data-centers is carried out as service function chaining (SFC) by linking ordered list of functions. With the development of software defined network (SDN) and network function virtualization (NFV), SFC has gained more attention in the industry for deploying larger applications. Provisioning different virtualized functions (VFs) of an SFC in different data-centers in a multi data-center environment is a challenging task. Existing works on serving SFC select a service function path (SFC) along which the VFs are executed. However, none of the works provide the optimal solutions considering both the execution and data transfer delay along with optic electric optic (OEO) conversion delay. In this work, a global optimal solution for SFP selection has been developed considering queuing, processing, transmission and OEO conversion delay. The proposed dynamic solution can work in a heterogeneous environment. Performance evaluation of the proposed algorithm shows that, significant performance improvement in respect of total execution delay of an SFC can be achieved compared to state-of-the-art works.

  • VNF management method using VNF Group Table in Network Function Virtualization

    This paper proposes efficient VNF management method using VNF Group Table in NFV (NFV : Network Function Virtualization), which is gaining attention from many network operator. ETSI ISG NFV WG is researching NFV. It refers to concept of utilizing network function in server OS rather than the equipment. Currently, ETSI ISG WG are divided into six groups, is standardizing, but need to study on the basis of traffic classification aspects or performance metrics. Therefore, in this thesis, research is conducted to create and utilize the VNF Group Table at NFV MANO to propose efficient VNF management techniques in terms of traffic statistics from NFV management.

  • Enhanced LTE handover scheme using NFV for LTE handover delay reduction

    As the number of devices using LTE network increases, the demand for real-time applications such as mobile cloud access, augmented reality, and voice over IP (VoIP) is also on the increase. To support such real-time applications in mobile environments, a new handover technology for low latency is required. In 5G systems, network functions virtualization (NFV) can be implemented for low latency handover. In this paper, LTE handover procedure is analyzed based on the 3GPP standard and delay performance of LTE handover when adopting NFV is presented.

  • A flexible multi-pop infrastructure emulator for carrier-grade MANO systems

    Developing a virtualized network service does not only involve the implementation and configuration of the network functions it is composed of but also its integration and test with management solutions that will control the service in its production environment. These integration tasks require testbeds that offer the needed network function virtualization infrastructure (NFVI), like OpenStack, introducing a lot of management and maintenance overheads. Such testbed setups become even more complicated when the multi point-of-presence (PoP) case, with multiple infrastructure installations, is considered. In this demo, we showcase an emulation platform that executes containerized network services in user-defined multi-PoP topologies. The platform does not only allow network service developers to locally test their services but also to connect realworld management and orchestration solutions to the emulated PoPs. During our interactive demonstration we focus on the integration between the emulated infrastructure and state-of-theart orchestration solutions like SONATA or OSM.

  • The Reliability Mapping Monitoring Method of Network Function Virtualization

    The traditional reliability monitoring method of network function virtualization neglects the virtual subnet configuration module, which leads to the lack of integrity of the method. With the increase of network function complexity, the monitoring accuracy will decline obviously. A new reliability mapping monitoring method for network architecture is proposed. The function of the virtual network configuration information is obtained through the virtual subnet configuration module. The virtual transmission module is used to connect the functional modules in the network virtualization system, obtain an overall mapping, and send a request to create a virtual subnet mapping. Finally, the mapping reliability detection module is used to receive the request of creating virtual subnet sent by virtual network transmission module. The experiment proves that compared with the traditional network function virtualization reliability monitoring method, the designed new mapping reliability monitoring method can increase the monitoring coincidence degree by 17% under the fixed complex network structure, which can effectively improve the reliability monitoring accuracy.
