Network Routers for use in data and telecommunication can be bought from eibabo in high-quality designs for residential and industrial applications. You will also find Ethernet hybrid adapters, and wireless LAN routers, among other things, also industrial routers and mobile industry routers, routers with SD card slot, and network routers with GSM / CSD / GPRS / EDGE module. Network routers are network devices with which you can forward data packets in networks between several computer networks. The data packets are between 64 and 1518 bytes long. The first six bytes encode the destination address, while the last four bytes contain a CRC checksum. The routed data packets then arrive either directly in the target network or at another router, which is also responsible for forwarding data packets. Network routers can, for example, be used for Internet connection, for safe coupling of several locations or for direct coupling of several local network segments. Routers can usually be configured for use in different network technologies (Ethernet, DSL, PPPoE, ISDN, ATM, etc.). When forwarding data packets, network routers make the routing decision based on information from network layer 3. Many routers are able to translate IP addresses (Network Address Translation, Port Address Translation, NAT / PAT) or to fulfill firewall functions.
