Routing．protocols use different techniques for assigning【S1】to individual networks．Further，each routing protocol forms a metric aggregation in a different．way．Most routing protocolscan use muh．iple paths if the paths have an equal【S2】．Some routing protocols can evenuse multiple paths when paths have an unequal cost．In either ease，load【S3】can improveoverall allocation of network bandwidth．When mulliple paths are used.there are several ways to distribute the packets．The two most common mechanisms are per—packet load balancing and per—destination load balancing．Per—packet load balancing distributes the【S4】across the possi-ble routes in a manner proportional to the route metrics．Per-destination load balancing distributes packets across the possible routes based on【S5】．【S1】A．callsB．metricsC．1inksD．destinations
