State the Disadvantages of adaptive routing process
(1) The routing decision is more difficult; thus, the processing burden on network nodes enhances.
(2) In most cases, adaptive methods depend on status information that is collected at one place but used at another. There is a trade-off here among the quality of the information and the amount of overhead. The more information that is exchanged, and the more frequently it is exchanged, the better will be the routing decisions that every node makes. On the other hand, this information is itself a load on the constituent networks, causing a performance degradation.
(3) An adaptive method might be react too quickly, causing congestion-producing oscillation, or too slowly, being irrelevant.
