Dhcp Problem

DHCP is the acronym for Dynamic Host revisit Kyoto, which is one of the TCP/IP protocol clusters that is used to assign dynamic IP addresses to network clients. These assigned IP addresses are reserved by the DHCP server as a set of addresses consisting of multiple addresses, and they are generally a contiguous address. Most enterprise networks now use a DHCP server to uniformly assign TCP/IP configuration information to clients. This approach not only reduces the day-to-day maintenance of network management staff workload, and the enterprise ...

The company recently expanded its Office business and established subsidiaries in many areas.

If you want to reduce the time available for desktop support and configuration for your users, you cannot use the local operating system. 0 clients emerged. Virtual Desktop Infrastructure (VDI) can deliver the operating system to end users in a better way, but it still needs to use terminal equipment. In this case, I usually choose thin clients, but they also need to use their own operating system. A series of local configurations are also required. If you can avoid using the operating system, you can reduce potential factors that can cause problems. VDI provides the operating system to the user, but 0 customers ...

The most obvious feature of the Cloud Age data center is the large number of applications of virtualization technology, which makes the objects of operation and maintenance management change. Previous equipment is real, location is relatively fixed, relatively intuitive management. The result of virtualization technology is to "pool" these resources, so that all management objects into virtual, flexible migration of the logic exists, the resources in the data center physical location visibility becomes difficult. Cloud Data center era, what kind of network operational problems? With cloud computing and large data entering the landing phase, the next generation of data centers to support cloud computing and large data development battle ...
