What is a broadband router?

Broadband router is a new network product in recent years, it comes into being with the popularization of broadband. Broadband routers in a compact box integrated router, firewall, bandwidth control and management functions, with fast forwarding capabilities, broadband routers flexible network management and rich network status and so on. Most broadband routers are optimized for China's broadband applications, which can meet different network traffic environment, and have good adaptability and network compatibility. Most broadband routers use highly integrated design, integrated 10/100mbps Broadband Ethernet WAN interface, and built-in multiple-port 10/100mbps adaptive switch to facilitate multiple machines to connect the internal network and the Internet.

Broadband routers have high, medium and low grade points, high-grade enterprise-wide broadband router prices up to thousands of, and the current Low-cost broadband router has dropped to hundred yuan, its performance has been basically able to meet the needs of such as family, school dormitories, offices and other applications, become the current family, school dormitory users of the network of choice products. Can be widely used in families, schools, offices, Internet cafes, community access, government, enterprises and other occasions.

Broadband Router Function Introduction:

Mac Features

At present, the majority of broadband operators are the MAC address and user ID, IP address bundled together to authenticate users online. The broadband router with MAC address can write the MAC address on the network card, let the server authenticate the MAC address through the access, to obtain the broadband access authentication.

Network address Translation (NAT) features

Nat translates the IP addresses assigned to each computer in the LAN to the actual IP address of the legally registered Internet network, allowing each computer in the internal network to communicate directly with other hosts on the Internet.

Dynamic Host Configuration Protocol (DHCP) features

DHCP can automatically assign IP addresses to client workstations that are logged on to a TCP/IP network. It provides secure, reliable, and simple network settings to avoid address conflicts. This is very important for home users.

Firewall features

A firewall can scan the network data that flows through it, filtering out some of the attack information.
Firewalls can also turn off unused ports to prevent hackers from attacking. It also prevents specific ports from leaking information, and prevents access from special sites.

Virtual Private Network (VPN) features

VPN can use Internet public network to establish a proprietary private network, a secure VPN including tunneling, encryption, authentication, access control and audit technology. For enterprise users, this function is very important, not only can save money, but also to ensure enterprise information security.

DMZ features

The main role of the DMZ is to reduce the risk of providing services for untrusted customers. The DMZ separates public hosts and local network facilities. Most broadband routers can only choose a single PC to open the DMZ function, but also some full-featured broadband routers can set up multiple PCs to provide the DMZ function.

DDNS function

DDNS is a dynamic Domain Name service, can map the user's dynamic IP address to a fixed domain name resolution server, so that IP address and fixed domain name binding, complete domain name resolution task. DDNS can help you build a virtual host to publish information in your own domain.

Routing is the activity of moving information from a source location to a target location through interconnected networks. In general, information passes through at least one or more intermediate nodes during routing. Typically, people compare routes and exchanges, mainly because the functionality that is achieved by the average user is exactly the same. In fact, the main difference between routing and switching is that the exchange takes place in the second layer of the OSI Reference Model (the Data Link layer), and the routing occurs on the third layer, the network layer. This distinction determines that routing and switching need to use different control information in the process of moving information, so the two ways to achieve their respective functions are different.
