Abstract
A method for managing data congestion and/or contention occurring at a point-of-traffic concentration. The method includes reading a time value associated with a data packet, the time value being representative of when the data packet entered the network. The time value is within the header of the data packet. The age of the data packet is determined from the time value. The data packet is discarded if the age of the data packet is above a threshold value. Alternatively, a first time value determined from a time reference is associated with a data packet at a first node. The data packet is transmitted to a second node and the first time value is compared to a second time value to provide a result. The second time value is also determined from the time reference. The data packet is discarded if the result exceeds a threshold value.
