Routing: We’re Moving Now!

Before a message can be passed to its target, it has to be formed; the message is enveloped inside a packet, which is formed by putting the address information of the target as a header of the actual message, so that the destination of the message and its size etc. can be read before the actual message is received. The actual message is then encoded in order to lessen transmittal time. This finalized packet is what gets "pushed out of the door". Now our message is ready to be routed to its destination node. Routing is the act of moving a message from a source node or other network entity to its destination. A routing technique is a way of handling the message as it passes through individual nodes. A routing algorithm is a rule set for determining where to send a message next. There are several routing techniques used by entities accessing the Internet lets explore some of these routing techniques and algorithms.
