The name " router " comes from the English word "route" - route, route. The first full-fledged router was developed in 1974, and by 1976 three routers based on 16-bit minicomputers formed the basis of an experimental prototype of the Internet. High-speed modern routers are, in fact, very specialized computers that perform, in addition to routing, specific security functions such as cryptographic conversion. Routers are connected to at least two communication networks - as a rule, these are two local area networks (LAN) or two wide area networks (WAN), or LAN and ISP (Internet Service Provider Networks). Routers are installed at gateways - the junction of two or more networks. To determine the best paths for transmitting information, routers use routing headers and tables, and to communicate with each other and configure the most optimal route between host servers, protocols such as ICMP. Router classification: Border routers are installed at the border of the network and provide its connection to external networks. These routers use the EBGP protocol. There are two types of border routers - subscriber, installed on the side of end users (enterprises), as well as label border routers used in high-performance telecommunication networks and transferring data from one network node to another using labels. Interprovider service border routers are designed to connect and exchange information between ISP networks. Core routers are communication devices between computers and the network backbone. This kind of router provides the fastest data link interfaces. To organize the work of home and small offices, wired and wireless routers are used, which provide routing and configuration of information in the routing table. They also filter incoming and outgoing traffic. Some wireless routers combine the functions of a network switch and a firewall.
