Routers
A host(node) with more than one interface to network
In layering terminology, a device which works at network layer
In the most basic form, a router takes packets sent to it on one interface(link), looks at its destination IP address and
sends it to destination if it’s directly accessible
sends it to another router if it believes that it can move the packet to the destination
drops the packet if no information about destination is available
Functions of a Router
Packet forwarding.
Sharing routing information, itself known as "routing“.
Packet filtering.
Network Address Translation (NAT)
Protocol translation/tunneling
Packet encryption/decryption
CLOUD Backup
