principle that 70% of network traffic flows inside a VLAN and 30% of the traffic flows between VLANs, VLAN logic can be divided by workflow, functional department, or geographical location. The division technology can be implemented based on switch ports, Nic MAC physical addresses, and layer-3 network protocol layer. In these three division technologies, in particular, the implementation method based on s

VLAN technology: VLANs have the following advantages: Broadcast storm of ① control network ② Ensure network security ③ simplifies network management 1, VLAN overview VLAN (virtual local area network) is a fictitious LAN, which is a new technology to realize virtual workgroup

The development of wireless local area network is more and more fierce, it has high access rate, flexible network, especially in the transmission of mobile data has a unique advantage. However, with the development of WLAN application field, the security problems are more and more important. In a wired network, you can

Ethernet switches are expanding their applications to the network core. This is mainly from two aspects: one is that Ethernet switches have the function of routers, not even, there are more than three layers of switches; the second is the maturity of the physical layer technology and the Exchange technology makes the Ethernet break through the area of the LAN, and can implement the

In many routing protocols, OSPF has many advantages, such as its adaptability to all sizes of the network (up to thousands of routers), no self loop, support zoning, can route classification. Let's focus on the division of the region, and before we start, let's take a look at some basic knowledge about zoning: 1, our network can be seen as the composition of a n

A storage area network (SAN) is a high-speed network or sub-network that provides data transmission between a computer and a storage system. A storage device is one or more disk devices used to store computer data. A San network consists of the communication structure of the

ObjectiveWith the decline in the price of computer hardware and machine, and the gradual simplification of the use method, more and more families now have more than two computers. Because the number of computers in a home area network is generally not large, there is no need to adopt a client/server approach. In the case of a large number of home computers, the computer is connected to form a small local

hardware, install the appropriate driver or protocol, and instruct the user to complete all configuration steps. This article describes two networking scenarios under the Windows XP operating system and describes the various features that Windows XP uses for the local area network. I. Objectives: Make up a home area netwo
