from the perspective of filtering network traffic, the role of router is very similar to switch and bridge. However, different from the switches that work in the physical layer of the network and divide the network segments physically, routers use special software protocols to divide the whole network logically. For example, a router supporting IP protocol can divide the network into several sub network segments, and only the network traffic pointing to the special IP address can pass through the router
for each received packet, the router will recalculate its check value and write a new physical address. Therefore, the speed of forwarding and filtering data by router is often slower than that of the switch which only looks at the physical address of the packet. However, for those complex networks, the use of routers can improve the overall efficiency of the network. Another obvious advantage of router is that it can automatically filter network broadcast. Generally speaking, the whole installation process of adding routers to the network is much more complicated than plug and play switches
some routers only support a single protocol, but most routers can support multiple protocols, namely multi protocol routers. Because each protocol has its own rules, to complete multiple protocol algorithms in a router will inevitably rece the performance of the router. The main task of the router is to find an optimal transmission path for each data frame passing through the router, and effectively transmit the data to the destination site
It can be seen that the strategy of choosing the best path, that is, the routing algorithm, is the key to the routerin order to complete this work, the routing table, which is the relevant data of various transmission paths, is stored in the router for routing selection. The path table contains the information of subnet, the number of routers and the name of the next router. The path table can be fixed by the system administrator
static routing table:
the system administrator sets a fixed path table in advance, which is called static path table
dynamic routing table:
dynamic routing table is a routing table automatically adjusted by the router according to the operation of the network system P>
router is a multi port device, which can connect simultaneous interpreting of different transmission rates and operate in LAN and WAN of different environments, and can also adopt different protocols. Router belongs to the third layer of OSI model network layer
guides the data transmission from one network segment to another, and also guides the data transmission from one network to another
first, network interconnection:
routers support various LAN and WAN interfaces, which are mainly used to interconnect LAN and wan to realize communication between different networks
Second, data processing:provides functions such as packet filtering, packet forwarding, priority, multiplexing, encryption, compression and firewall
Third, network management:routers provide functions including router configuration management, performance management, fault tolerance management and flow control
the so-called "routing" refers to the behavior and action of transferring data from one place to another. Router is the machine that performs such behavior and action. Its English name is router, which is a network device connecting multiple networks or network segments. It can "translate" the data information between different networks or network segments, So that they can "read" each other's data, thus forming a larger network
in order to complete the "routing" work, the routing table, which is the relevant data of various transmission paths, is stored in the router for routing selection. The routing table contains the label information of the subnet, the number of routers on the network and the name of the next router. The routing table can be fixed by the system administrator, dynamically modified by the system, automatically adjusted by the router, or controlled by the host
in the router, there are two concepts of address names: static routing table and dynamic routing table. The fixed routing table is set by the system administrator in advance, which is called static routing table. Generally, it is set in advance according to the configuration of the network when the system is installed. It will not change with the change of the future network structure
