Networks use different routing protocols to select the best routing path to reach other networks. A distance-vector routing uses a set of protocols (IPX, SPX, IP, or DECnet) and a distance calculation through an outgoing network interface to select the most efficient path to a network destination.
Link-state routing protocols track the connection status and type to each link that comes from a network. The criteria for selection are links with greater hops and faster mediums. Those are considered the most efficient links that will be used by the routing protocols.
In your opinion, are there other options that can perform the tasks of these protocols? What is the future for routing through these protocols? Explain.
