nfv network function virtualization

After completing this course, you will be able to: Describe the basic concepts of NFV Understand the development trend of NFV network technology Understanding the NFV Architecture Describe the relationship between NFV and SDN Understand the key capab

Use NFV and SDN to implement 5G network slicing and nfvsdn5 g Slicing Network Slicing Network slicing will play a key role in the implementation of 5g, which allows operators to run multiple virtual networks on a single physical infrastructure. With the 5g commercialization in 2020, many people are wondering to what e

RedHat announced its cooperation with NEC, a global leader in innovative IT, network and communication products and solutions, to jointly develop the NetworkFunctionsVirtualization and NFV functions, assists in providing the Red Hat Enterprise LinuxOpenStack platform solution with the NFV function of the Telecom grade.

I. Creating and managing virtual machines using Virt-manager 1. Use the VNC Viewer connection to enter the virtualization platform host 2. Open the terminal input Virt-manager command to start the Virt-manager Virtual Machine management interface #virt-manager 3. Install CentOS 6.6 virtual machines via Virt-manager Click on the icon to create a new virtual machine: Choose PXE boot, there is a system Automation deployment server in My

. If the network system is a function machine, the system and hardware are bundled together at the factory, then SDN is the Android system, can be installed on many smartphones, upgrade, but also to install more powerful mobile app (SDN Application Layer Deployment) "Because the firmware of a traditional network device (switch, router) is locked and controlled by

With the increasing demand for application integration, more and more users hope to improve resource utilization by integrating or sharing physical assets. The pooling of physical resources in the data center can not only increase by 50% ~ 60% utilization, and rapid deployment and re-deployment of resources, while also reducing physical equipment, cables, space, power, cooling, and other needs, it can meet the rapidly changing business development needs. The

the underlying physical network. NSX can be deployed on any IP network, including all traditional network models and the next generation architecture provided by any vendor, without the need to refactor the underlying network. It is easy to see that the core idea of VMware NSX is to migrate the server

first, identify all types of network equipment and network Connections Because network virtualization adds a lot of virtual network devices (including virtual NICs) to the physical machine, the situation becomes complex, so first we need to distinguish them. Of course, if y

SR-Iovbackground:The pass-through model allows virtual machines to use physical devices directly, which makes the network performance of the

system is deployed, the entire architecture is fixed. After server virtualization, one of the major advantages of deploying virtual machines is to increase the flexibility of service deployment and improve the reliability of services. Therefore, virtual opportunities are constantly migrated over the network. This requires that when the virtual machines are migrated to new servers, the corresponding

Virtualization has brought a lot of gifts to the IT department. It makes it impossible not only to become possible, to become more popular. From server consolidation to cloud computing, virtualization is currently the dominant computing platform in the world. In addition to expanding computing power, virtualization is also considered a way to increase

Reprinted from: http://mabofeng.blog.51cto.com/2661587/1020375The network is the foundation of VMware VSphere 5.1, and all virtual machines require a network for communication. If all virtual machines are considered to be physical machines, then on the network topology, different network connection devices and methods

Network virtualization-FlowVisor: Network Virtual Layer (medium) 1. Concepts understanding and review As mentioned in the previous blog, slice is defined as an instance of a virtual network, and a sliced stream can be considered as a sub-space of the whole geometric space consisting of headers of all possible data pac

shortly after using the virtualization framework. The details of the problem are not important, but they have a great impact. Before virtualization, the impact of such problems was limited, but the cascade failure of the Sharing Platform caused the interruption of many business units. This problem is difficult to fix. It requires several patches to ensure stable operation of the platform. However, the loss

configuration Note: macvtap has poor performance on Windows virtual machines and is not recommended. Comparison of vhost_net macvtap The macvlan function is to configure multiple MAC addresses for the same physical network card. This allows you to configure multiple Ethernet ports in the software vendor.Macvtap is used to replace the tun/TAP and bridge kernel modules. macvtap is based on the macvlan modul

unable to support environments with changing and unpredictable capacity requirements. In traditional networks, engineers struggle with layer-2 and layer-3 configurations, tedious access/distribution/core architecture, and management of traffic and ports of physical switches, routers, and firewalls; there are also various bandwidth problems for LAN and WAN. Even worse, the 802.1q standard only provides a maximum of 4094 VLANs, which is far from enough for cloud providers or large enterprises tha
