What are the common types of fiber access routers and switches, and what is the price?

Common devices are routers, switches, and firewalls. What are the common brands of optical fiber access equipment?

1. Huawei Huawei

Huawei's routers, switches, and firewall brands are relatively good in China. The quality is relatively good, and the quality is relatively moderate! Huawei is a well-known trademark in China, and in 1988, Huawei was the world's leading provider of telecommunications solutions.

2. H3C H3C communication technology, IP technology and product research, development, production, sales and service.

3. Cisco Cisco

Cisco Systems, a leading provider of Internet solutions, is one of the top 10 switch brands. But Cisco's switches are relatively expensive!

4. D-link Friendly News.

5. TP-LINK.

In 1996, it was one of several companies with completely independent R&D and manufacturing capabilities.

Fiber optic router refers to fiber optic backbone router? It is used with the best package on the network, and there are few ports, which are dedicated to network providers. Generally not used in the unit;

Optical fiber router also refers to the gateway type router with optical fiber interface in the network Bari, which is different from the backbone router, and the difference with the switch is: a small amount of IP may be done, so that more machines can access the Internet;

It is characterized by Internet access, and has the function of a layer 2 switch, which is about 1,000 yuan;

Optical fiber switch is a large switch with optical fiber interface, generally a three-layer switch (the small one at home is a two-layer), which can access the network client and is used to access a large local area network, can be used as a virtual network, and has the best function, the main feature is that the function of the local area network is strong, more expensive than the second type, ** in about 10,000 yuan;

Whether it's fiber or regular broadband, the speed at which you apply is constant, and the more computers you share, the greater the impact on each other; You want to use it to log in to the router, and the general combination has admin admin, admin none, guest guest and other combinations.

One has a WAN port and the other does not have a WAN port A router is more powerful than a switch, but more expensive than a switch (under the same conditions).

The functions in the network are basically the same, but the biggest difference is that each port of the switch enjoys a dedicated bandwidth and has the function of data exchange, so that the network transmission performance can be used to transmit a large amount of data at the same time; A hub, on the other hand, is a bandwidth shared by all ports.

Router: A device that connects to various local area networks and WANs on the Internet, and it will automatically select and set routes according to the situation of the channel, and send signals in the order of the best path. The English name of the router is router, and the router is the hub of the Internet"Traffic police"。

At present, routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet.

In your case, use a wireless router Now ** and the like are sold only about 100 There is a network cable interface on the wireless router and you can use a wireless router to connect My family is this method.

Wireless routers can not only set up a wireless LAN, but also allow the LAN to share broadband Internet access (connecting the LAN and the external network);

The switch can only be used to build a local area network, and cannot be used to connect the local area network and the external network.

The router can be used as a switch (the WAN port is not used empty), but the switch cannot be used as a router.

Almost all routers have built-in DHCP servers, and ordinary switches do not have DHCP servers (that is, the function of automatically assigning IP addresses);

Most routers have firewall functions, and ordinary switches almost do not have firewall functions.

What is a switch and how is it different from a router? Take you to an in-depth look at both.

Take the route first! Use method 2 on the line, method 1 light cat out of the device BC can not be on the network.

With way 2.

In option 1, there are often conflicting dials.

1. The functions are different.

The switch is equivalent to an additional network interface, just like a network of ten people, there is no enough interface, at this time you can plug in the switch, but if you want to surf the Internet, you must use a router at this time. In other words, the switch needs to dial separately for Internet access, and the router can share a broadband.

2. Different addressing methods.

The switch addresses based on the MAC address. Routers work at the network layer and are addressed based on IP addresses.

3. The number of connected networks is different.

The switch can be connected to multiple computers to form a local area network, and the switch does not have the function of automatic identification of data sending and arriving addresses by the router.

4. Firewall services are different.

The router is able to provide a firewall server, and the router can only send specific packets.
