The method further includes first storing the incoming packet in the at least one first type of queue if the packet is from a first source, second storing the incoming packet in the at least one second type of queue if the packet is from a second source, and sending the incoming packet to a desired destination. Additionally, a method for avoiding out-of-ordering of frames in a network including the steps of receiving an incoming packet at a network switch, determining if the incoming packet is from a high speed source, first storing the incoming packet in a first type of queue, if the incoming packet is from said high speed source, and second storing the incoming packet in a second type of queue, if the incoming packet is from a lower speed source. Additionally, a step of sending the incoming packet stored in one of the first queue and the second queue using a first-in first-out operation.
