Generally, the failure of a vswitch is caused by the time used. As the Working Hours extend and network applications change, the chance of a problem increases greatly. A switch is an important device in a network. If a problem occurs, it will affect

As the main connection device of LAN, Ethernet switches have become one of the fastest network devices widely used in applications. At the same time, with this rapid development, the functions of switches are constantly enhanced, the upgrade of the

In order to adapt to the challenges brought by the deepening of network applications, the scale and speed of the network are rapidly developing. The speed of the LAN has increased from 10 Mbit/s to 100 Mbit/s, currently, Gigabit Ethernet technology

A hub is a connection device connected to multiple computers or other devices in a computer network. It is the smallest unit for centralized network management. A hub is a collection of branches, just like the trunk of a tree. Many types of networks

In-depth introduction to the specific testing solution of Huawei gigabit switches. The following describes the performance testing problems of Huawei gigabit switches. The purpose of this evaluation is to make an objective comparison of each

User-controlled switches are quite common. So I studied the types and functions of these switches and shared them here, hoping to be useful to you. A user-controlled switch is a dedicated switch for internal telephone exchanges between industrial

Virtualization is undoubtedly the biggest computing trend in the past decade. By separating the elements of different computing platforms, more and more enterprise users have moved to virtual machines in the "one application, one server" mode to

There are many things worth learning about data exchange technology. Here we mainly introduce various types of data exchange technology. Today, the concept of network is deeply rooted in the hearts of the people. In our daily life, everyone is

Currently, the mainstream Gigabit backbone switches have high forwarding capabilities and smaller sizes. They are suitable for common users. Among the six Ethernet switches we have tested, EDIMAX ES-5800R and LeaPComm6004 switch is not manageable

1. When to use the multi-route protocol? When two different routing protocols need to exchange routing information, they need to use multiple routing protocols. Of course, route redistribution can also exchange route information. Multi-route
