?How is routing through a wide area network accomplished?

What will be an ideal response?


Consider the Internet as an example: It is a massive collection of networks, routers, and communications lines (various types of telephone lines). When a data packet enters a router, the router examines the IP address encapsulated in the network layer of the packet and determines where the packet should go next. When there are multiple routes through a network such as the Internet, how is any one particular route selected? Although routing on the Internet is fairly complex, it is possible to examine the basic routing techniques that all types of wide area networks employ. But keep in mind that a wide area network does not use only one form of routing. The routing algorithms used within the Internet, for example, are actually combinations of several types of basic routing techniques.?To begin to understand the often complex issue of routing, it is helpful to think of the sub-network as a graph consisting of nodes (computers, routers, or telephone switches) and edges (the communications links between the nodes).
