Abstract:
In a communication network, a method for minimizing delay associated with hops among a plurality of network nodes, the method comprising the steps of:receiving a data packet with a first priority by a first network node, remarking by the first network node a header of the data packet with a different priority from the first priority for processing by a second network node; queuing the data packet by the first network node; determining whether a queuing position of the data packet is below a threshold, if the queuing position of the data packet is greater than the threshold, then the step of remarking with a different priority includes a step of changing by the first network node the first priority included in the header to indicate a next higher priority queue; marking by the first network node the first priority in the header with a quality of service classification; and marking the first priority indicator with a differentiated services code point (DSCP) indication, if no quality of service classification is indicated.
