Routers Improve Communication Capabilities

Shenzhen Hongdian Corporation | Updated: Jul 28, 2017

Advantages of application Characteristics of routers

1, because the router has the ability to carry on the complex route choice computation, can reasonable, the intelligent choice best path, therefore, is suitable for joins more than 2 large scale and has the complex network topology structure network

2, the router can isolate broadcast storm information in the source network, Router thus reducing and suppressing the impact of the broadcast storm

3, Multi-Protocol routers can connect networks using different communication protocols, so it can be used as a network interconnection platform using different communication protocols.

4, the network of single protocol routers interconnection, can use the same or different protocol on 1-2 level; the same routable protocol is used on tier 3rd: The 4th tier requires the same or compatible protocol 5, the use of routers to isolate unwanted traffic, Router so that interconnected networks maintain their own independent management control and improve the security performance of the network. As a result, routers are often used as firewalls, restricting the internal network of intranet (Internet) and external networks to intranet access, Router which plays a role of network shielding.

6. Routers can also be used as network bridges to handle non-routable protocols

7, Router network segmentation function, can improve network performance, reduce the burden of host

8, able to provide reliable transmission, priority services, and do not need to communicate with each other network to maintain a permanent connection

The router has the function of judging the network address and choosing the IP path, it can establish the flexible connection in the Multi network interconnection environment, use the completely different data grouping and the media access method to connect various subnets, the router only accepts the information of the source station or other router, belonging to the network layer's interconnection equipment. Router It does not care about the hardware devices used by the subnets, but requires software that is consistent with the network layer protocols.

Routers are divided into local routers and remote routers, which are used to connect network transport media, such as optical fiber, coaxial cable, twisted pair; Remote routers are used to connect remote transmission media and require appropriate devices such as telephone lines to be equipped with modems, Router wireless receivers and transmitters.

Routers are the main node devices of the Internet. Routers determine the forwarding of data through routing. Forwarding policy is called routing selection (routing), Router which is also the origin of router names (router, forwards). As the hub of interconnection between different networks, the router system constitutes the main thread of Internet based on TCP/IP, and it can be said that routers form the backbone of Internet. Router Its processing speed is one of the main bottlenecks of network communication, and its reliability and stability directly affect the quality of network interconnection.

Therefore, in the campus intranet, regional intranet, and even the entire Internet research field, the router technology is always in the core position, its development course and the direction, becomes the entire Internet research epitome. In the current situation of network infrastructure and information construction in China, the paper probes into the role, status and development direction of routers in interconnection networks, Router and it is of great significance for the research of Domestic network technology, network construction and the definition of the specious concepts of routers and networks interconnection in the network market.

In recent years, the exchange of router products, in essence, it is not a new technology, but in order to improve communication ability, the principle of the switch to the router, so that the data transmission capacity faster and better.
