routing in circuit-switching networks has traditionally involved a static routing strategy with the use of(71)paths to respond to increased load . modern routing strategies provide more adaptive and flexible approaches . the routing function of a packet-switching network attempts to find the least-cost route through the network , with cost based on the number of (72),expected delay , or other metrics in virtually all packet-switching networks , some sort f adaptive routing technique is used . adaptive routing algorithms typically rely on the(73)information about traffic conditions among nodes . in most cases , adaptive strategies depend n status information that is(74)at one place but used at another . there is a tradeoff here tween the quality of the information and the amount of(75). the exchanged information itself a load on the constituent networks , causing a performance degradation.(71)A.only B.single C.alternate D.series(72)A.hops B.sites C.members D.points(73)A.exchange B.transportationC.reception D.transmissio(74)A.rejected B.collected C.discarded D.transmitted(75)A.packets B.information C.data D.overhead
