Abstract:
1. An apparatus to forward packets with controlled delay, comprising: first logic to hold a packet in a first class for a quelling time of a predetermined controlled delay value; scheduling logic to delay transmission of the packet in the first class until the queuing time reaches the predetermined controlled delay value, and to determine whether to delay transmission of a packet in a second class to allow the transmission of the packet in the first class when the queuing time reaches the predetermined controlled delay value; and time-stamping logic to attach time-stamp information including a time value to the packet in the first class; wherein the scheduling logic delays transmission of the packet in the second class in response to determining that transmission of the packet in the second class would complete after the queuing time reaches the predetermined controlled delay value; wherein the first logic accesses the time-stamp information; wherein the queuing time starts at the time value and ends at the predetermined controlled delay value after the time value; and wherein the predetermined controlled delay value is independent of the time value.
