ABSTRACT:
An apparatus comprising a plurality of ingress ports coupled to a plurality of upstream nodes, the ingress ports having an incoming data rate; and a plurality of egress ports coupled to the ingress ports and an aggregated link comprising a plurality of links, the aggregated link having a bandwidth capacity, wherein at least some of the upstream nodes reduce their data transfer rates to a rate greater than zero when the incoming data rate is greater than or about equal to the aggregated link's bandwidth capacity. Also disclosed is a network component comprising a processor configured to implement a method comprising varying a plurality of transmission rates at a rate greater than zero, wherein the transmission rates correspond to a plurality of nodes that send data over an aggregated link.
