LAN Server Setup

The so-called Local area network (Network,lan) is used to interconnect a limited range of computers, terminals and external devices in a confined area, such as a laboratory, an office building, or a campus.

Under normal circumstances:

Less than 10 people, smaller companies generally have less demand for network applications, because of the small number of people, there is no need to partition VLAN (virtual local area network), so the choice of a multi-port switch is sufficient.

10 people-100-person scale enterprise, need routing function and subnetting. It is generally more appropriate to configure the Router + switch. Routers provide the partitioning of intranet and extranet links and VLANs, as well as the configuration of various firewalls and routing functions. The switch is connected to the router as a subnet, and the other end is linked to each terminal in the subnet. Divide several subnets, then connect a few switches from the route.

Build structure such as: Now the more popular corporate LAN generally choose a tree topology structure (extension of the star topology). The tree topology has the following advantages: 1, easy fault diagnosis, 2, easy to upgrade the network.

　　

And for 100 to 500 people of enterprises, pay attention to the rate of intranet. The scenario of a three-layer switch + two-layer switch is generally used. The three-layer switch, as the core of the network, provides the configuration, partitioning, and data exchange between the various VLANs, each of which is formed by a layer two switch. Network backbone equipment selection, it is recommended that the network backbone equipment or core equipment to choose a 3rd-level switching function of the high-performance backbone switch. If you require high reliability and availability of the LAN backbone, you should also consider the redundancy of the core switch and the design of the hot backup scheme. The network device type of the aggregation layer or the access layer, usually select the ordinary switch, the performance and quantity of the switch is determined by the number of network computers and the topology structure.
