In layman's Hyper-V network virtualization (sequential)

. 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

1: N network device virtualization technology (MDC)

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

A simple discussion from the SDN originator Nicira to the VMware NSX Network virtualization Platform

Fully integrated network virtualization technology (1)

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

Four ways to improve security for network virtualization

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

When network virtualization is insufficient to solve the problem

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

Does virtualization require network management programs?

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
